Spring 2.0 introduces comprehensive support for using classes and objects that have been defined using a dynamic language (such as JRuby) with Spring. This support allows you to write any number of classes in a supported dynamic language, and have the Spring container transparently instantiate, configure and dependency inject the resulting objects.
The dynamic languages currently supported are:
JRuby 0.9 / 1.0
Groovy 1.0 / 1.5
BeanShell 2.0
Fully working examples of where this dynamic language support can be immediately useful are described in Section 26.4, “Scenarios”.
Note: Only the specific versions as listed above are supported in Spring 2.5. In particular, JRuby 1.1 (which introduced many incompatible API changes) is not supported at this point of time.
This bulk of this chapter is concerned with describing the dynamic language support in detail. Before diving into all of the ins and outs of the dynamic language support, let's look at a quick example of a bean defined in a dynamic language. The dynamic language for this first bean is Groovy (the basis of this example was taken from the Spring test suite, so if you want to see equivalent examples in any of the other supported languages, take a look at the source code).
Find below the Messenger
interface that the
Groovy bean is going to be implementing, and note that this interface is defined
in plain Java. Dependent objects that are injected with a reference to the
Messenger
won't know that the underlying
implementation is a Groovy script.
package org.springframework.scripting; public interface Messenger { String getMessage(); }
Here is the definition of a class that has a dependency on the
Messenger
interface.
package org.springframework.scripting; public class DefaultBookingService implements BookingService { private Messenger messenger; public void setMessenger(Messenger messenger) { this.messenger = messenger; } public void processBooking() { // use the injected Messenger object... } }
Here is an implementation of the Messenger
interface
in Groovy.
// from the file 'Messenger.groovy' package org.springframework.scripting.groovy; // import the Messenger interface (written in Java) that is to be implemented import org.springframework.scripting.Messenger // define the implementation in Groovy class GroovyMessenger implements Messenger { String message }
Finally, here are the bean definitions that will effect the injection of the
Groovy-defined Messenger
implementation into
an instance of the DefaultBookingService
class.

To use the custom dynamic language tags to define dynamic-language-backed beans,
you need to have the XML Schema preamble at the top of your Spring XML
configuration file. You also need to be using a Spring
For more information on schema-based configuration, see Appendix C, XML Schema-based configuration. |
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:lang="http://www.springframework.org/schema/lang" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.0.xsd"> <!-- this is the bean definition for the Groovy-backed Messenger implementation --> <lang:groovy id="messenger" script-source="classpath:Messenger.groovy"> <lang:property name="message" value="I Can Do The Frug" /> </lang:groovy> <!-- an otherwise normal bean that will be injected by the Groovy-backed Messenger --> <bean id="bookingService" class="x.y.DefaultBookingService"> <property name="messenger" ref="messenger" /> </bean> </beans>
The bookingService
bean (a
DefaultBookingService
) can now use its private
messenger
member variable as normal because the
Messenger
instance that was injected
into it is a Messenger
instance. There is nothing special going on here, just plain Java and
plain Groovy.
Hopefully the above XML snippet is self-explanatory, but don't worry unduly if it isn't. Keep reading for the in-depth detail on the whys and wherefores of the above configuration.
This section describes exactly how you define Spring managed beans in any of the supported dynamic languages.
Please note that this chapter does not attempt to explain the syntax and idioms of the supported dynamic languages. For example, if you want to use Groovy to write certain of the classes in your application, then the assumption is that you already know Groovy. If you need further details about the dynamic languages themselves, please consult Section 26.6, “Further Resources” at the end of this chapter.
The steps involved in using dynamic-language-backed beans are as follows:
Write the test for the dynamic language source code (naturally)
Then write the dynamic language source code itself :)
Define your dynamic-language-backed beans using the appropriate
<lang:language/>
element in the XML
configuration (you can of course define such beans programmatically
using the Spring API - although you will have to consult the source
code for directions on how to do this as this type of advanced
configuration is not covered in this chapter). Note this is an iterative
step. You will need at least one bean definition per dynamic
language source file (although the same dynamic language source
file can of course be referenced by multiple bean definitions).
The first two steps (testing and writing your dynamic language source files) are beyond the scope of this chapter. Refer to the language specification and / or reference manual for your chosen dynamic language and crack on with developing your dynamic language source files. You will first want to read the rest of this chapter though, as Spring's dynamic language support does make some (small) assumptions about the contents of your dynamic language source files.
The final step involves defining dynamic-language-backed bean definitions,
one for each bean that you want to configure (this is no different from
normal JavaBean configuration). However, instead of specifying the
fully qualified classname of the class that is to be instantiated and
configured by the container, you use the <lang:language/>
element to define the dynamic language-backed bean.
Each of the supported languages has a corresponding
<lang:language/>
element:
<lang:jruby/>
(JRuby)
<lang:groovy/>
(Groovy)
<lang:bsh/>
(BeanShell)
The exact attributes and child elements that are available for configuration depends on exactly which language the bean has been defined in (the language-specific sections below provide the full lowdown on this).
One of the (if not the) most compelling value adds of the dynamic language support in Spring is the 'refreshable bean' feature.
A refreshable bean is a dynamic-language-backed bean that with a small amount of configuration, a dynamic-language-backed bean can monitor changes in its underlying source file resource, and then reload itself when the dynamic language source file is changed (for example when a developer edits and saves changes to the file on the filesystem).
This allows a developer to deploy any number of dynamic language source files as part of an application, configure the Spring container to create beans backed by dynamic language source files (using the mechanisms described in this chapter), and then later, as requirements change or some other external factor comes into play, simply edit a dynamic language source file and have any change they make reflected in the bean that is backed by the changed dynamic language source file. There is no need to shut down a running application (or redeploy in the case of a web application). The dynamic-language-backed bean so amended will pick up the new state and logic from the changed dynamic language source file.
| Note | |
|---|---|
Please note that this feature is off by default. |
Let's take a look at an example to see just how easy it is to start using
refreshable beans. To turn on the refreshable beans
feature, you simply have to specify exactly one
additional attribute on the <lang:language/>
element
of your bean definition. So if we stick with
the example from earlier
in this chapter, here's what we would change in the Spring XML configuration
to effect refreshable beans:
<beans> <!-- this bean is now 'refreshable' due to the presence of the 'refresh-check-delay' attribute --> <lang:groovy id="messenger" refresh-check-delay="5000" <!-- switches refreshing on with 5 seconds between checks --> script-source="classpath:Messenger.groovy"> <lang:property name="message" value="I Can Do The Frug" /> </lang:groovy> <bean id="bookingService" class="x.y.DefaultBookingService"> <property name="messenger" ref="messenger" /> </bean> </beans>
That really is all you have to do. The 'refresh-check-delay'
attribute defined on the 'messenger'
bean definition
is the number of milliseconds after which the bean will be refreshed with
any changes made to the underlying dynamic language source file.
You can turn off the refresh behavior by assigning a negative value
to the 'refresh-check-delay'
attribute.
Remember that, by default, the refresh behavior is disabled. If you don't
want the refresh behavior, then simply don't define the attribute.
If we then run the following application we can exercise the refreshable feature;
please do excuse the 'jumping-through-hoops-to-pause-the-execution'
shenanigans in this next slice of code. The System.in.read()
call is only there so that the execution of the program pauses while I (the author)
go off and edit the underlying dynamic language source file so that the refresh will
trigger on the dynamic-language-backed bean when the program resumes execution.
import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.springframework.scripting.Messenger; public final class Boot { public static void main(final String[] args) throws Exception { ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml"); Messenger messenger = (Messenger) ctx.getBean("messenger"); System.out.println(messenger.getMessage()); // pause execution while I go off and make changes to the source file... System.in.read(); System.out.println(messenger.getMessage()); } }
Let's assume then, for the purposes of this example, that all
calls to the getMessage()
method of
Messenger
implementations have to be
changed such that the message is surrounded by quotes.
Below are the changes that I (the author) make to the
Messenger.groovy
source file when the execution of
the program is paused.
package org.springframework.scripting class GroovyMessenger implements Messenger { private String message = "Bingo" public String getMessage() { // change the implementation to surround the message in quotes return "'" + this.message + "'" } public void setMessage(String message) { this.message = message } }
When the program executes, the output before the input pause will be
I Can Do The Frug
. After the change
to the source file is made and saved, and the program resumes execution,
the result of calling the getMessage()
method on the
dynamic-language-backed Messenger
implementation
will be 'I Can Do The Frug'
(notice
the inclusion of the additional quotes).
It is important to understand that changes to a script will
not trigger a refresh if the changes occur
within the window of the 'refresh-check-delay'
value.
It is equally important to understand that changes to the script are
not actually 'picked up' until a method is called
on the dynamic-language-backed bean. It is only when a method is called on a
dynamic-language-backed bean that it checks to see if its underlying script
source has changed. Any exceptions relating to refreshing the script
(such as encountering a compilation error, or finding that the script
file has been deleted) will result in a fatal
exception being propagated to the calling code.
The refreshable bean behavior described above does
not apply to dynamic language source files
defined using the <lang:inline-script/>
element
notation (see Section <IP_ADDRESS>, “Inline dynamic language source files”).
Additionally, it only applies to beans where
changes to the underlying source file can actually be detected;
for example, by code that checks the last modified date of a
dynamic language source file that exists on the filesystem.
The dynamic language support can also cater for dynamic language
source files that are embedded directly in Spring bean definitions.
More specifically, the <lang:inline-script/>
element allows you to define dynamic language source immediately
inside a Spring configuration file. An example will perhaps make the
inline script feature crystal clear:
<lang:groovy id="messenger"> <lang:inline-script> package org.springframework.scripting.groovy; import org.springframework.scripting.Messenger class GroovyMessenger implements Messenger { String message } </lang:inline-script> <lang:property name="message" value="I Can Do The Frug" /> </lang:groovy>
If we put to one side the issues surrounding whether it is good practice
to define dynamic language source inside a Spring configuration file, the
<lang:inline-script/>
element can be useful in
some scenarios. For instance, we might want to quickly add a Spring
Validator
implementation to a Spring MVC
Controller
. This is but a moment's work
using inline source. (See Section 26.4.2, “Scripted Validators”
for such an example.)
Find below an example of defining the source for a JRuby-based bean
directly in a Spring XML configuration file using the
inline:
notation. (Notice the use of the <
characters to denote a '<'
character. In such a case
surrounding the inline source in a <![CDATA[]]>
region might be better.)
<lang:jruby id="messenger" script-interfaces="org.springframework.scripting.Messenger"> <lang:inline-script> require 'java' include_class 'org.springframework.scripting.Messenger' class RubyMessenger < Messenger def setMessage(message) @@message = message end def getMessage @@message end end </lang:inline-script> <lang:property name="message" value="Hello World!" /> </lang:jruby>
There is one very important thing to be aware of with regard to Spring's dynamic language support. Namely, it is not (currently) possible to supply constructor arguments to dynamic-language-backed beans (and hence constructor-injection is not available for dynamic-language-backed beans). In the interests of making this special handling of constructors and properties 100% clear, the following mixture of code and configuration will not work.
// from the file 'Messenger.groovy' package org.springframework.scripting.groovy; import org.springframework.scripting.Messenger class GroovyMessenger implements Messenger { GroovyMessenger() {} // this constructor is not available for Constructor Injection GroovyMessenger(String message) { this.message = message; } String message String anotherMessage }
<lang:groovy id="badMessenger" script-source="classpath:Messenger.groovy"> <!-- this next constructor argument will *not* be injected into the GroovyMessenger --> <!-- in fact, this isn't even allowed according to the schema --> <constructor-arg value="This will *not* work" /> <!-- only property values are injected into the dynamic-language-backed object --> <lang:property name="anotherMessage" value="Passed straight through to the dynamic-language-backed object" /> </lang>
In practice this limitation is not as significant as it first appears since setter injection is the injection style favored by the overwhelming majority of developers anyway (let's leave the discussion as to whether that is a good thing to another day).
From the JRuby homepage...
“ JRuby is an 100% pure-Java implementation of the Ruby programming language. ”In keeping with the Spring philosophy of offering choice, Spring's dynamic language support also supports beans defined in the JRuby language. The JRuby language is based on the quite intuitive Ruby language, and has support for inline regular expressions, blocks (closures), and a whole host of other features that do make solutions for some domain problems a whole lot easier to develop.
The implementation of the JRuby dynamic language support in Spring is
interesting in that what happens is this: Spring creates a JDK dynamic
proxy implementing all of the interfaces that are specified in the
'script-interfaces'
attribute value of the
<lang:ruby>
element (this is why
you must supply at least one interface in the value
of the attribute, and (accordingly) program to interfaces when using
JRuby-backed beans).
Let us look at a fully working example of using a JRuby-based bean. Here is
the JRuby implementation of the Messenger
interface that was defined earlier in this chapter (for your convenience it
is repeated below).
package org.springframework.scripting; public interface Messenger { String getMessage(); }
require 'java' class RubyMessenger include org.springframework.scripting.Messenger def setMessage(message) @@message = message end def getMessage @@message end end # this last line is not essential (but see below) RubyMessenger.new
And here is the Spring XML that defines an instance of the
RubyMessenger
JRuby bean.
<lang:jruby id="messageService" script-interfaces="org.springframework.scripting.Messenger" script-source="classpath:RubyMessenger.rb"> <lang:property name="message" value="Hello World!" /> </lang:jruby>
Take note of the last line of that JRuby source ('RubyMessenger.new'
).
When using JRuby in the context of Spring's dynamic language support, you are encouraged
to instantiate and return a new instance of the JRuby class that you want to use as a
dynamic-language-backed bean as the result of the execution of your JRuby source. You
can achieve this by simply instantiating a new instance of your JRuby class on the last
line of the source file like so:
require 'java' include_class 'org.springframework.scripting.Messenger' # class definition same as above... # instantiate and return a new instance of the RubyMessenger class RubyMessenger.new
If you forget to do this, it is not the end of the world; this will however result in
Spring having to trawl (reflectively) through the type representation of your JRuby class
looking for a class to instantiate. In the grand scheme of things this will be so fast
that you'll never notice it, but it is something that can be avoided by simply
having a line such as the one above as the last line of your JRuby script. If you don't
supply such a line, or if Spring cannot find a JRuby class in your script to instantiate
then an opaque ScriptCompilationException
will be thrown immediately after the source is executed by the JRuby
interpreter. The key text that identifies this as the root cause of an
exception can be found immediately below (so if your Spring container
throws the following exception when creating your dynamic-language-backed bean
and the following text is there in the corresponding stacktrace, this will hopefully
allow you to identify and then easily rectify the issue):
org.springframework.scripting.ScriptCompilationException: Compilation of JRuby script returned ''
To rectify this, simply instantiate a new instance of whichever class you want to expose as a JRuby-dynamic-language-backed bean (as shown above). Please also note that you can actually define as many classes and objects as you want in your JRuby script; what is important is that the source file as a whole must return an object (for Spring to configure).
See Section 26.4, “Scenarios” for some scenarios where you might want to use JRuby-based beans.
From the Groovy homepage...
“ Groovy is an agile dynamic language for the Java 2 Platform that has many of the features that people like so much in languages like Python, Ruby and Smalltalk, making them available to Java developers using a Java-like syntax. ”If you have read this chapter straight from the top, you will already have seen an example of a Groovy-dynamic-language-backed bean. Let's look at another example (again using an example from the Spring test suite).
package org.springframework.scripting; public interface Calculator { int add(int x, int y); }
Here is an implementation of the Calculator
interface in Groovy.
// from the file 'calculator.groovy'
package org.springframework.scripting.groovy
class GroovyCalculator implements Calculator {
int add(int x, int y) {
x + y
}
}
<-- from the file 'beans.xml' --> <beans> <lang:groovy id="calculator" script-source="classpath:calculator.groovy"/> </beans>
Lastly, here is a small application to exercise the above configuration.
package org.springframework.scripting; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Main { public static void Main(String[] args) { ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml"); Calculator calc = (Calculator) ctx.getBean("calculator"); System.out.println(calc.add(2, 8)); } }
The resulting output from running the above program will be
(unsurprisingly) 10
.
(Exciting example, huh? Remember that the intent is to illustrate the
concept. Please consult the dynamic language showcase project for a
more complex example, or indeed Section 26.4, “Scenarios”
later in this chapter).
It is important that you do not define more than one class per Groovy source file. While this is perfectly legal in Groovy, it is (arguably) a bad practice: in the interests of a consistent approach, you should (in the opinion of this author) respect the standard Java conventions of one (public) class per source file.
The GroovyObjectCustomizer
interface is a callback that allows you to hook additional
creation logic into the process of creating a Groovy-backed bean.
For example, implementations of this interface could invoke
any required initialization method(s), or set some default property
values, or specify a custom MetaClass
.
public interface GroovyObjectCustomizer { void customize(GroovyObject goo); }
The Spring Framework will instantiate an instance of your Groovy-backed
bean, and will then pass the created GroovyObject
to the specified GroovyObjectCustomizer
if one has been defined. You can do whatever you like with the supplied
GroovyObject
reference: it is expected
that the setting of a custom MetaClass
is what most
folks will want to do with this callback, and you can see an example
of doing that below.
public final class SimpleMethodTracingCustomizer implements GroovyObjectCustomizer { public void customize(GroovyObject goo) { DelegatingMetaClass metaClass = new DelegatingMetaClass(goo.getMetaClass()) { public Object invokeMethod(Object object, String methodName, Object[] arguments) { System.out.println("Invoking '" + methodName + "'."); return super.invokeMethod(object, methodName, arguments); } }; metaClass.initialize(); goo.setMetaClass(metaClass); } }
A full discussion of meta-programming in Groovy is beyond the scope of the
Spring reference manual. Consult the relevant section of the Groovy
reference manual, or do a search online: there are plenty of articles
concerning this topic.
Actually making use of a GroovyObjectCustomizer
is easy if you are using the Spring 2.0 namespace support.
<!-- define the GroovyObjectCustomizer just like any other bean --> <bean id="tracingCustomizer" class="example.SimpleMethodTracingCustomizer" /> <!-- ... and plug it into the desired Groovy bean via the 'customizer-ref' attribute --> <lang:groovy id="calculator" script-source="classpath:org/springframework/scripting/groovy/Calculator.groovy" customizer-ref="tracingCustomizer" />
If you are not using the Spring 2.0 namespace support, you can still
use the GroovyObjectCustomizer
functionality.
<bean id="calculator" class="org.springframework.scripting.groovy.GroovyScriptFactory"> <constructor-arg value="classpath:org/springframework/scripting/groovy/Calculator.groovy"/> <!-- define the GroovyObjectCustomizer (as an inner bean) --> <constructor-arg> <bean id="tracingCustomizer" class="example.SimpleMethodTracingCustomizer" /> </constructor-arg> </bean> <bean class="org.springframework.scripting.support.ScriptFactoryPostProcessor"/>
From the BeanShell homepage...
“ BeanShell is a small, free, embeddable Java source interpreter with dynamic language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript. ”
In contrast to Groovy, BeanShell-backed bean definitions require some (small)
additional configuration. The implementation of the BeanShell dynamic language
support in Spring is interesting in that what happens is this: Spring creates
a JDK dynamic proxy implementing all of the interfaces that are specified in the
'script-interfaces'
attribute value of the
<lang:bsh>
element (this is why
you must supply at least one interface in the value
of the attribute, and (accordingly) program to interfaces when using
BeanShell-backed beans).
Let's look at a fully working example of using a BeanShell-based bean
that implements the Messenger
interface
that was defined earlier in this chapter (repeated below for your
convenience).
package org.springframework.scripting; public interface Messenger { String getMessage(); }
Here is the BeanShell 'implementation' (the term is used loosely here) of the
Messenger
interface.
String message; String getMessage() { return message; } void setMessage(String aMessage) { message = aMessage; }
And here is the Spring XML that defines an 'instance' of the above 'class' (again, the term is used very loosely here).
<lang:bsh id="messageService" script-source="classpath:BshMessenger.bsh" script-interfaces="org.springframework.scripting.Messenger"> <lang:property name="message" value="Hello World!" /> </lang:bsh>
See Section 26.4, “Scenarios” for some scenarios where you might want to use BeanShell-based beans.
The possible scenarios where defining Spring managed beans in a scripting language would be beneficial are, of course, many and varied. This section describes two possible use cases for the dynamic language support in Spring.
One group of classes that may benefit from using dynamic-language-backed beans is that of Spring MVC controllers. In pure Spring MVC applications, the navigational flow through a web application is to a large extent determined by code encapsulated within your Spring MVC controllers. As the navigational flow and other presentation layer logic of a web application needs to be updated to respond to support issues or changing business requirements, it may well be easier to effect any such required changes by editing one or more dynamic language source files and seeing those changes being immediately reflected in the state of a running application.
Remember that in the lightweight architectural model espoused by projects such as Spring, you are typically aiming to have a really thin presentation layer, with all the meaty business logic of an application being contained in the domain and service layer classes. Developing Spring MVC controllers as dynamic-language-backed beans allows you to change presentation layer logic by simply editing and saving text files; any changes to such dynamic language source files will (depending on the configuration) automatically be reflected in the beans that are backed by dynamic language source files.
| Note | |
|---|---|
In order to effect this automatic 'pickup' of any changes to dynamic-language-backed beans, you will have had to enable the 'refreshable beans' functionality. See Section <IP_ADDRESS>, “Refreshable beans” for a full treatment of this feature. |
Find below an example of an
org.springframework.web.servlet.mvc.Controller
implemented using the Groovy dynamic language.
// from the file '/WEB-INF/groovy/FortuneController.groovy' package org.springframework.showcase.fortune.web import org.springframework.showcase.fortune.service.FortuneService import org.springframework.showcase.fortune.domain.Fortune import org.springframework.web.servlet.ModelAndView import org.springframework.web.servlet.mvc.Controller import javax.servlet.http.HttpServletRequest import javax.servlet.http.HttpServletResponse class FortuneController implements Controller { @Property FortuneService fortuneService ModelAndView handleRequest( HttpServletRequest request, HttpServletResponse httpServletResponse) { return new ModelAndView("tell", "fortune", this.fortuneService.tellFortune()) } }
<lang:groovy id="fortune" refresh-check-delay="3000" script-source="/WEB-INF/groovy/FortuneController.groovy"> <lang:property name="fortuneService" ref="fortuneService"/> </lang:groovy>
Another area of application development with Spring that may benefit from the flexibility afforded by dynamic-language-backed beans is that of validation. It may be easier to express complex validation logic using a loosely typed dynamic language (that may also have support for inline regular expressions) as opposed to regular Java.
Again, developing validators as dynamic-language-backed beans allows you to change validation logic by simply editing and saving a simple text file; any such changes will (depending on the configuration) automatically be reflected in the execution of a running application and would not require the restart of an application.

Please note that in order to effect the automatic 'pickup' of any changes to dynamic-language-backed beans, you will have had to enable the 'refreshable beans' feature. See Section <IP_ADDRESS>, “Refreshable beans” for a full and detailed treatment of this feature. |
Find below an example of a Spring
org.springframework.validation.Validator
implemented using the Groovy dynamic language. (See Section 5.2, “Validation using Spring's Validator
interface”
for a discussion of the Validator
interface.)
import org.springframework.validation.Validator import org.springframework.validation.Errors import org.springframework.beans.TestBean class TestBeanValidator implements Validator { boolean supports(Class clazz) { return TestBean.class.isAssignableFrom(clazz) } void validate(Object bean, Errors errors) { if(bean.name?.trim()?.size() > 0) { return } errors.reject("whitespace", "Cannot be composed wholly of whitespace.") } }
This last section contains some bits and bobs related to the dynamic language support.
It is possible to use the Spring AOP framework to advise scripted beans. The Spring AOP framework actually is unaware that a bean that is being advised might be a scripted bean, so all of the AOP use cases and functionality that you may be using or aim to use will work with scripted beans. There is just one (small) thing that you need to be aware of when advising scripted beans... you cannot use class-based proxies, you must use interface-based proxies.
You are of course not just limited to advising scripted beans... you can also write aspects themselves in a supported dynamic language and use such beans to advise other Spring beans. This really would be an advanced use of the dynamic language support though.
In case it is not immediately obvious, scripted beans can of course be scoped
just like any other bean. The scope
attribute on the
various <lang:language/>
elements allows you to
control the scope of the underlying scripted bean, just as it does with a
regular bean. (The default scope is
singleton, just as it
is with 'regular' beans.)
Find below an example of using the scope
attribute
to define a Groovy bean scoped as a
prototype.
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:lang="http://www.springframework.org/schema/lang" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.0.xsd"> <lang:groovy id="messenger" script-source="classpath:Messenger.groovy" scope="prototype"> <lang:property name="message" value="I Can Do The RoboCop" /> </lang:groovy> <bean id="bookingService" class="x.y.DefaultBookingService"> <property name="messenger" ref="messenger" /> </bean> </beans>
See Section 3.5, “Bean scopes” in Chapter 3, The IoC container for a fuller discussion of the scoping support in the Spring Framework.
Find below links to further resources about the various dynamic languages described in this chapter.
Some of the more active members of the Spring community have also added support for a number of additional dynamic languages above and beyond the ones covered in this chapter. While it is possible that such third party contributions may be added to the list of languages supported by the main Spring distribution, your best bet for seeing if your favourite scripting language is supported is the Spring Modules project.


Font-size sets the overall scale of your text. You can use a lot of different units to set the font size. Some of these units you are probably familiar with if you have used text editors before such as pt size or you can use px size. However, these methods are not advised because they are static and will not adapt based on screen size.
This property sets the font face. There are a collection of Web safe fonts that generally each browser has agreed to support, but there is an infinite number of different fonts. The problem is they might not all look the way you want them to on different browsers.
That is why this property "font-family" allows a list of fonts in the order of your preference. This comma-separated list orders your font preference from left to right. In our above example, our first choice is Helvetica, if the browser doesn't support that it will move to the next on the list, Verdana, and if it still doesn't support that it will just pick any sans-serif font it does support. You should always end your font family with fonts that are likely to be supported by the browser, this way I am guaranteed to have control over the font-family.
Something to keep in mind: some fonts have names with multiple words like "Times New Roman" or "Century Gothic". When using these fonts you'll need to surround the entire name with quotes so the browser understands that is a single font name


Many applications will use Couch Potato exclusively within the context of their routing configurations, whether they use ngRoute, ui-router, or some other router (e.g. angular-detour or the inbuilt router in pre-2.0 versions of angular).
The reasoning is that you are trying to lazy-load and register components that are used in the context of something must happen when the user visits a certain route/state of the application. This page describes such usage in general. See Ad Hoc Lazy Loading for alternative usage.
When routes or states are invoked, an angular promise can resolved, and the $couchPotato service can invoke the $couchPotatoProvider to use RequireJS to download and register dependencies in the context of the promise.
Since each component registers itself, indirect dependencies specified in AMD form are downloaded and registered along with the directly stated dependencies of the route.
Couch Potato does not care which dependencies are resolved when the route is invoked. It is an application's responsibility to specify directly or indirectly all requirements.
For example, if a route depends on a Couch Potato component named "base-state-components", and that component depends on another component named "base-Services", then all base services will be registered when the state "base", which depends on the component "base-state-components" is activated.
The documented configurations for Couch Potato are:


IN DREAMS Reviewed by Jamie Peck
Things start out strong enough, with cinematographer Darius Khondji's stunning camera work guiding viewers into the bowels of a underwater ghost town during a creepy prologue that establishes a notably grim tone right off the bat. This eerie opulence remains a dazzling display of showmanship throughout the entire film - there's even something macabre about the way Khondji photographs a rustic, seemingly innocent New England autumn - but if there ever was a film that didn't deserve so good a polish, it's this one. Don't knock the look, but say what you will about the foolish plot, underdeveloped characters and flat dialogue.
Annette Bening, another asset "In Dreams" shouldn't be so lucky to boast, gives an increasingly effective performance in a role that doesn't do much for her in return. She plays Claire Cooper, a Massachusetts children's book illustrator who's plagued by terrifying nightmares involving kidnaped children. She thinks these visions are a warning knell for horrible, soon-to-be-committed crimes, but neither her ho-hum husband (Aidan Quinn) nor the ho-hummer police can muster up the sense to take her seriously. This being a thriller, we know that she is, in fact, on the money, and it's a credit to Bening's acting that she delves equally into Claire's madness and compassion.
But as soon as a body turns up and Claire has given the authorities reason enough to believe her claims, "In Dreams" trades in its nifty supernatural chills for a long series of allegedly spooky jolts that simply refuse to make sense.  Subplots appear and disappear. When Claire finally comes face-to-face with our evil murderer (Robert Downey Jr.), it turns out his name is Vivian, he's clairvoyant and he's got some major issues with mama, a la Norman Bates. "In Dreams" reaches its absurdist zenith here, and the climax drags with mumbled revelations and laughable twists.
 Are the drawings on the wall blood or paint? Who cranked up the Andrews Sisters on the CD player and caused the swing to move on its own? What about the computer? Does Vivian possess the gift of telekinesis in addition to his other powers? Why would he continually endanger Claire if she was necessary for his ultimate plan? Is the woman in Australia integral to anything? And the aforementioned flooded city - what function does that _really_ serve? Sigh. At least in my own dreams, I can imagine a better movie where certain talent didn't go to waste.

SnapHunt is a mobile application for android devices. SnapHunt aims to change the way people interact with their cities, and gives business new tools to promote their products and services. It uses Google Maps to display interesting geopoints on a map given by users locations where they would go to and take a picture. The picture has to be something related to a theme given by the app, and the objective is for users to guess what the application wants them to take a picture of. Then, the SnapHunt would use Clarifai API to recognize the picture taken by the user, and tell him if he is correct or not by using image recognition. Our backend on PHP was used to allow people go online and compete, and see other people in the map as they are also snapping and hunting objects. A MySQL database was used to store our data. SnapHunt was developed during ConUHacks, Concordia University Hackathon in Montreal, Quebec. Below you may find information about its tech stack and APIs used to make this possible.

CodeFemme is one of the 'girls only repositories' in Opencode'19 here, at IIIT Allahabad. This website is created for the girls and by girls with the whole-soul aim to promote the contribution of female developers in the world of opensource. Empowering women and giving them a chance to showcase their creativity and skill in ths vast domain of web development is the ultimate goal that we aspire to achieve.
This portal contains the efforts of all the contributors as shown in the section below and also highlights the achievements of females in different technical competitions and events.
It was a great experience for me. I enjoyed a lot doing different things for the competition like opening issues, solving them, claiming issues opened by the organizers, creating pull requests. It gave me real happiness whenever my PR was merged. It was a great event and I am thankful to all the mentors to guide and motivate me throughout the event.


Class bridge (server)
Class defined in:core/server/bridge.js:1
The Bridge is responsible for communication between the client and server during app delivery. The bridge flushes payloads and instructions to the client delivery engine, which downloads the payload dependencies before inserting the payload into the page.
The bridge can be used by the Server Controller to load dependencies or make explicit calls into client side JS modules.
call
( module_name, function_name, args
)
core/server/bridge.js:49
Invokes a function in a client JS module.
Parameters:-
module_name
<String>the module name to load. This should be a full path from the app root (app/client/some_module, f.e.)
-
function_name
<String>function name to call. This should be exposed in the module.exports of the module being loaded.
-
args
<Mixed> (*..n)the arguments to pass the invoked function. Any Components passed in will be properly marshalled to the client and instantiated before calling this function.
controller
( controller_name, function_name, args
)
core/server/bridge.js:82
Invokes a function on a controller. This is useful for passing state to the client controller during the initial page delivery.
Parameters:-
controller_name
<String>the controller name (as just the module_name, not a complete path) to invoke the function on.
-
function_name
<String>the function to call on the controller.
-
args
<Mixed> (*..n)any arguments to use when invoking the controller. Any Components used will be automatically marshalled before invoking this function on the client.
raw
( javascript_code
)
core/server/bridge.js:70
Injects raw JS into the page. Generally, this is used internally and not for external consumption.
Parameters:-
javascript_code
<String>the javacsript code to insert into this page.
render
(
) /* private method */
core/server/bridge.js:165
Renders any queued up bridge invocations as a string to deliver to the client. This is used by core/server/page when generating the page
The raw HTML for the bridge invocations to be run on the client.

Trizbort.io is a browser-based tool that lets you easily map adventure games. Drag rooms into your map and link them up using connections in all compass directions. Add a list of objects present in each room. Finally, export your map straight to your adventure game toolkit of choice: TADS, Inform, Quest or Alan.
Trizbort.io lets you edit the properties of your rooms using a quick and intuitive editor. Set room name and description, then add room colors, room borders and elliptical or octagonal room shapes.
Add named objects with descriptions to your rooms, and even create containment relationships - which will be included in your code generation later.
Trizbort.io can export your map to various adventure game development systems. It supports TADS, Inform, Quest and Alan, among others. You can also export to YAML if that fits in your development pipeline. Code is generated for your rooms, connections and objects, and you can feed it straight into your compiler.

LJBook is a service that can convert your LiveJournal entries into a PDF document. Its quite nice. I plan to use this service every year. You can get my journal entries in book form here:
LiveJournal2004Public.pdf.
Why you would want it, is something you will have to answer for yourself. I want it for posterity sake. These journal entries are a time capsule of me, and my view of the world at a particular point in time.. *sigh*
The only thing I don't like about it is that I have to supply my LiveJournal username and password, unencrypted even. This should be a premium service that LiveJournal provides, in my opinion.
Anyway, you can try LJBook for yourself:

Here, we will discuss whatever this page is about. You're trash at explaining things, but whatevs.
Remember to keep new sentences on a new line (not <br>, though) so you can read them in the editor window.
Add a picture too:
If vector a goes 3 up and 2 over, and b goes 1 up and 3 over, then vector a + b goes up 4 (3 + 1 up) and 5 over (2 + 3 over).
It's worth noting that vectors or matrices that are not of the same size cannot be added together!
This means you cannot add a 4x2 matrix to a 5x3 matrix. This also applies to vectors.
Steps:
Add the first element in both matrices, then the second, third, and so on...
Remember that this only works since we are trying to add two matrices that have the same size!
This is different in matrix multiplication, where you might multiply a 3x2 matrix by a 2x3 matrix.
3) Let's try another one, but this time with different dimensions:

Inevitably your workflow will be interrupted by problems. This tutorial will show you how to deal with the ones you will most likely come across: * merge conflicts * commits to be undone * changes to be stashed
A merge conflict
arises when you try to merge
two branches with contradictory lines, which may arise when two collaborators edit the same line. This can be avoided if your team is clear on what lines each member is working on, but Sourcetree allows you to fix them before completing the merge.
As an example, let’s make one edit: change one line to a line, and commit that (in a fix-xme
branch)
Checkout development
branch, refresh the repository status and pull the latest changes (1 has been flagged).
Now attempt to merge the fix-xme
branch into `development branch.
Sourcetree has detected a conflict, and has flagged them in the files. You can follow the window’s advice to resolve them with Sourcetree, but you can also do it in the text editor.
Let’s resolve them in the text editor. Open the file with the detected conflicts and search for the text “<<<<<<< HEAD”. Each conflict will have this as an opening tag (HEAD
refers to the remote version; i.e. the version that your collaborator(s) created). The closing tag will be labelled with the branch: the version that you created and are trying to merge with.
Confer with your collaborators on how you want to resolve the conflict, delete the tags and move on to the next conflict. When you have finished resolving the conflicts, save the file(s) and commit to the branch you are merging into (i.e. development
).
??? You may run into some weird files in your File Status
tab: leave these unstaged, and make sure the file you want to stage has the yellow square icon. Keep an eye on the diff to make sure that you are committing the correct changes.
Now you can commit (you can leave the commit message as is).
Congratulations! You have successfully merged your branches! It is now ahead of the remote
branch by 2 commits(?), and you may now push
it.
You can now check to see that your commit has made it on the Git web user interface.
There are several ways you can undo a commit.

You can also undo specific ‘hunks’, by selecting Reverse hunk
on a specific change. This will initiate a new process of staging
and committing
.
Alternatively, you can do a “hard reset” of the branch. Select the commit
you want to revert to, right click, and select Reset current branch to this commit
.  You may reset your branch to a remote commit, but this will not affect the commits on the remote repository.
Stashing
your changes is an alternative “saving” method of committing
: you stow away the changes you have made without contributing them to the branch
. This is necessary when you’re switching between branches but don’t want to commit
something incomplete.
Select Stash
on your uncommitted changes.
Give your stash a name and confirm.

Later, when you return to working on your changes, you may choose to Apply
them back to your branch (returning them to where you last left them), or simply Delete
them from your branch altogether.


What To Know Before Starting A Beauty Business In 2020
Starting a beauty business is not easy but if you follow some of our advice then you can create something really special.
What To Know Before Starting A Beauty Business In 2020
Many people dream of becoming a beautician and starting their own beauty business but this industry can be extremely competitive. Of course, for those who do succeed, it can be very lucrative as so many people are invested in improving their appearance in 2019.
For those of you who are interested in starting a beauty business in 2020, we have put together some things that you should know. Keep reading to find out what made our list.
You’ll Need Insurance
The first thing on your to-do list might not be to get some insurance but this can be extremely important. Depending on the level of risk involved in your industry, and particular field, you could be putting yourself in danger without the right insurance for beauticians. Some of the common practices covered by companies like Hiscox include lash tinting and UV tanning which can be dangerous. Make sure to find the right policy before opening your salon.
If you are thinking about starting a beauty business then you should know that it is extremely competitive. So many people are seeing the perks of starting a beauty business this year and so the industry is becoming quite cluttered. If you want to stand out and reach customers then you need to offer something different. Think about offering special treatments and getting some extra training.
Social Media Is Key
The next thing that you need to know before you start a beauty business in 2020 is that social media is key. Many beauty brands both big and small are using social media to reach their target audience and it is working. If you are starting a local business then ask your friends and family to share your posts, get them to model for you and this will really increase your reach. If you have the budget for it, consider using Facebook ads because they can also work quite well.
You Don’t Need A Salon
Finally, you should know that you don’t need to own a salon to start a successful beauty business in 2020. Many people are opting for mobile beauticians now as it is more convenient and this could work in your favour. A salon only brings overheads and it can reduce your profit. Consider getting a van that you can use to get around and come to your clients and this might give you the edge.
Final Verdict
If you really want to start your own beauty business in 2020 then you should make sure to take on board our advice. Think about the insurance that you will need to protect your new business and make sure that you understand how social media works. This way, you can be sure that your new beauty business is going to be a success and you can stand out from the crowd. Soon, you’ll have a great business and you’ll be ready to take on 2020.

Iran's Minister Says Only Way to Counter US Sanctions Is to Boost Defence Power
Iran's defence minister Brigadier-General Amir Hatami said on Saturday that the sanctions of the US "will not fade away and the only way to counter them is improving the power in every vital field", especially in the military field.
The Defence Minister made the remarks on Saturday at the Meeting on Countering Defence Sanctions.
“The enemy has targeted Iran's existence. They don’t want to hurt Iran; they intend to delete it,” said Hatami, cited by IRNA, adding that Iran’s enemies are trying to penetrate the infrastructure as well as the cultural, political, and economic programs of Iran.
Some countries are actors, some are playmakers and some are pure followers, Hatami added, saying that today, Iran has become a regional playmaker in the region through resistance, reliance on internal capabilities and the development of defence power.
“The power of Iran has been a result of nothing, but relying on domestic capacities,” he added.

A cause I am very passionate about is Autism Speaks, a non-profit organization dedicated to funding global biomedical research into the causes, prevention, treatments and a possible cure for autism.
Autism Speaks is the national philanthropy for my sorority, Alpha Xi Delta, and I have had the opportunity to organize four major philanthropy events over the past two years.


WAYNE'S WORLD A film review by Mark Santora Copyright 1992 Mark Santora
Tonight I got a chance to see an advance screening of WAYNE'S WORLD. Based on the sometimes comical skit on SATURDAY NIGHT LIVE, I had mixed feelings going into this film.  This film is really funny.
Quick Summary: Wayne has a public access television show he runs from his basement. Garth is is best friend and sidekick on the show. The show is really popular in their small town. A big time producer (Rob Lowe) sees the show. He decides to buy the show and make it more commercial. By the way, Rob Lowe is the "bad" guy in this film, but you knew that already I'm sure.
Both Wayne and Garth address the camera directly. They do it really well too. Fortunately they don't overuse this and allow a small story to develop around the characters. They also take time out to poke fun at everyone. Reebok, Pizza Hut, Nuprin, ... nobody is too far away to attack. But they do it smartly and do not insult the audience's intelligence.
Along the way, Wayne falls in love with a female rock singer. Rob Lowe attempts to steal her away. This leads to a scene with Alice Cooper as they sir around and discuss the philosophy of the town of Milwaukee. And while in Milwaukee, they don't forget to pay tribute to the two most famous people in Milwaukee, Laverene and Shirley. These scenes are really great. There is also a great scene where Wayne, Garth, and their three crew members are driving down the street singing "Bohemian Rhapsody." It is really good.
I don't want to give anything away, which is why I am being so vague. What I will say is that you should look for cameos by Ione Sky, Robert Patrick (grin), Ed O'Neil, and Chris Farley. They all play interesting roles.
How would I rate this movie? It is really funny. It is just the type of mindless humor that is what makes films fun. Don't expect to see any Oscar nominations, even though they even poke fun at that, just expect a good time.

The base class of all tokenizers. It sets up the scanner and manages the looping until all tokens have been extracted. It also provides convenience methods to make sure adjacent tokens of identical groups are returned as a single token.
| EOL | = | /(?=\r\n?|\n|$)/ |
| [R] | chunk | The current chunk of text being accumulated |
| [R] | group | The current group being processed by the tokenizer |

I recently bought an MSI Wind U200 notebook, which has RALink wireless firmware. The problem was that the kernel provided with my Linux distribution of choice - Frugalware - apparently didn't include the file required to get the wireless working. Output of "dmesg" reported that it was looking for a firmware file "rt3090.bin". I quickly confirmed that the file wasn't included in the ralink-firmware package, so I went to the RALink web site and downloaded the firmware package quoted for the 3090 chipset, which I guessed was what I needed. The problem was that even this didn't contain a "3090.bin" file. A little Internet searching later and I saw several people saying that simply creating a symlink named "rt3090.bin" to "/lib/firmware/rt2860.bin" would solve my problem. So I simply created that symlink and wireless has been working well ever since.
Problem solved!

[gecode-users] optimising with 'constrain'
Andrea Rendl
andrea.rendl at gmail.com
Thu Sep 4 17:36:55 CEST 2008
Hello everybody,
I'm trying to minimise a variable in my problem instance by adding the
following method (as member of my problem class that inherits from
Example):
void
constrain(Space* s) {
rel(this, variable, IRT_LE, static_cast<ProblemModel*>(s)->variable.val());
}
However, it has no effect: whenever I run the instance it gives me all
possible solutions, ignoring the minimisation constraint. I compared
my instance to some of the optimisation problems in the examples/
directory and could not see any difference. Do you have any idea what
I could have done wrong? When and where is 'constrain' called? I could
not find a description in the documentation...
Thanks for your help,
Andrea
