java.lang.SecurityManager
as the Default Security
ManagerThe Java SE JDK security architecture is policy-based, and allows for fine-grained access control. When code is loaded, it is assigned "permissions" based on the security policy currently in effect. Each permission specifies a permitted access to a particular resource, such as "read" and "write" access to a specified file or directory, or "connect" access to a given host and port. The policy, specifying which permissions are available for code from various signers/locations, can be initialized from an external configurable policy file. Unless a permission is explicitly granted to code, it cannot access the resource that is guarded by that permission. These new concepts of permission and policy enable the JDK to offer fine-grain, highly configurable, flexible, and extensible access control. Such access control can now not only be specified for applets, but also for all Java code, including applications, beans, and servlets.
For more information on the Java security architecture, please see the security documentaton.
The SecurityManager
class contains many methods
with names that begin with the word check
. Examples
are checkRead
and checkConnect
. Various
methods in the Java libraries call a check
method
before performing each potentially security-sensitive operation.
The security manager is thereby given an opportunity to prevent
completion of the operation by throwing an exception. A security
manager routine simply returns if the operation is permitted, but
throws a SecurityException if the operation is not permitted. The
only exception to this convention is
checkTopLevelWindow
, which returns a boolean
value.
The other main type of methods contained in the
SecurityManager
class are those related to class
loader existence and depth:
java.lang.SecurityManager
was an
abstract class. The default implementations of the security manager
check
methods threw exceptions. The class loader and
depth-related classes were appropriately implemented, often in
native code.
Any application (such as a browser) that wanted to install a
security manager had to write their own, providing appropriate
concrete implementations of the methods that threw exceptions by
default -- primarily the check
methods.
Security managers based on the JDK 1.1 applet security manager model typically based access control decisions on two things:
These types of decisions were made by calling the
SecurityManager
methods related to class loader
existence and depth. For example, a typical 1.1-style security
manager might have a checkExit
method like the
following:
public void checkExit(int status) { if (inClassLoader()) { throw new SecurityException(..); } }
Such a checkExit
method would not allow
Runtime.exit
to be called when any class defined with
a class loader (an applet) was on the stack. This is an example of
the first case, checking whether or not a class with a class loader
is on the stack. An example of the second case (class loader depth)
would be something like:
public void checkCreateClassLoader() { if (classLoaderDepth() == 2) { throw new SecurityException(); } }
This method is saying that the class loader depth can't be 2.
That is, the method that called the method that called
checkCreateClassLoader
must not be in a class defined
with a class loader. For example, the constructor for
java.lang.ClassLoader
calls
checkCreateClassLoader
, which means the method that
calls the constructor for java.lang.ClassLoader
must
not have a class loader. This means applets can't directly create
class loaders.
Note that there is a big difference between the two methods,
even though both attempt to prevent applets from performing
actions. In the first case, checkExit
will throw an
exception if an applet is anywhere on the stack. That means even
built-in JDK code can't exit the VM if it was called from an
applet. In the second case, JDK code is allowed to create a class
loader, even if it was called by an applet. That is because the
depth of a class with a class loader is used, and not the fact that
there is one.
java.lang.SecurityManager
had a
number of changes made to it in order to allow it to be used as the
default security manager for applications. In particular:
abstract
class, and can thus be
installed as-is.check
methods call a new
checkPermission
method, which by default calls the
method of the same name (checkPermission
) in the new
AccessController
class. Those methods that don't call
checkPermission
have reasonable defaults.java.security.AllPermission
.java.lang.SecurityManager
as the Default Security
ManagerSince java.lang.SecurityManager
is no longer
abstract, you can install and use it as the default security
manager. You can do this by setting a system property when
launching the VM:
java -Djava.security.manager YourAppAlternatively, your application can install it directly via the following line of code:
System.setSecurityManager(new SecurityManager());You can customize the behavior of the default security manager by modifying policy files. See the security guide on policy files for more information.
In the JDK, the SecurityManager
methods related to
class loaders and class loader depth are not called by any
of the check
methods, and they are deprecated. They
should not be used by any new security managers, and it is
recommended that their use be eliminated from existing security
managers as well. However, they are left in for backward
compatibility and they have been modified in an attempt to enable
old 1.1-style security managers to still work under the JDK,
without modification.
These methods are:
The class loader/depth related methods have all been modified in three ways:
ClassLoader.getSystemClassLoader
) or one of its
ancestors.
Since classes loaded by the system class loader include
application classes (loaded off of CLASSPATH
),
extension classes, and the built-in JDK classes, this modification
enables these methods to ignore such code.
Note that if you run an application that installs a custom
security manager, and that security manager is loaded off of
CLASSPATH
in the JDK, it will have a system class
loader associated with it. (Application classes did not have a
class loader in JDK 1.1.) If you were to call a method like
classLoaderDepth
from within the custom security
manager, and that method were not modified to ignore classes loaded
by a system class loader, it would always return 0, which would not
be very useful. Similarly, if class loader methods weren't changed
to skip system classes and a custom security manager was loaded off
of CLASSPATH
, then this might also open up security
holes in cases where the security manager is making decisions based
on, for example, disallowing an operation if "classLoaderDepth() ==
2". (It should really be "classLoaderDepth() <= 2".)
AllPermission
as if there is no class loader on the
stack.As an example of the use of the first two modifications, note
that there are now places in the JDK that open files, etc., after a
security manager has been installed. Some 1.1-style security
managers have a checkRead
method that looks like the
following:
public void checkRead(String file) { if (inClassLoader()) { throw new SecurityException(..); } }
Without JDK code modifications, such a check run in the JDK
would cause a security exception to be thrown when the JDK itself
tries to read a file and there is a class with a non-system class
loader on the stack. With the new security model, all such JDK code
that tries to perform an operation that its caller might not be
allowed to do has a doPrivileged
block around it.
Since inClassLoader
just examines the stack up to and
including the frame containing the "privileged" code, and the code
at the top of the stack is JDK code, which is loaded by the system
class loader or one of its ancestors, the
inClassLoader
method will return false
,
allowing the read to occur.
As noted previously, security managers based on the 1.1 applet
security manager based some of their access control decisions on
class loader depth. As an example, the
checkCreateClassLoader
method previously presented is
repeated here:
public void checkCreateClassLoader() { if (classLoaderDepth() == 2) { throw new SecurityException(); } }In the JDK we have attempted to maintain the stack depth as used in 1.1-style security managers. For example, the constructor for java.security.SecureClassLoader has an explicit call to
SecurityManager.checkCreateClassLoader
even though the
constructor for its super class (ClassLoader) also does. If the
check was not placed in the constructor for
SecureClassLoader
, then a 1.1-style security manager
would allow untrusted code to extend SecureClassLoader
and construct class loaders, as the class loader depth would always
be greater than 2.
First and foremost, we highly recommend analyzing all your custom security manager methods before running your security manager under the JDK. Failure to do so could result in a security hole or prevent the proper operation of the JDK. This is due to the fragile nature of 1.1-style security managers.
Where possible, you should just use the default implementation
of the 1.2 SecurityManager
. This helps give users and
administrators consistent behavior. If this is not possible, then
you should at least try to call super.checkXXX
in your
checkXXX
method before throwing a security exception.
Doing so will allow the access controller algorithm to be used, and
will allow the JDK itself to function correctly.
In the JDK, any existing code that used to call any of the
SecurityManager check
methods continues to do so. For
new code that requires a security check, calls are made to
SecurityManager.checkPermission
instead of adding a
new SecurityManager check
method. For example, the new
java.lang.System.setProperty
method calls
checkPermission
with a
java.util.PropertyPermission
permission.
When extending the SecurityManager class and overriding existing
methods, some care should be taken. For example, if you override
the checkRead(String file)
method so it always throws
a security exception, then the JDK itself may fail to operate
properly. That is, if some JDK code needs to open a file (to read a
properties file, load a JAR file, etc.) then throwing a security
exception for every read attempt would cause such opens to always
fail.
In general, you should only override the default methods if
you intend to loosen security, not to make it stronger. If
you want to tighten security, you should modify the default
policy files and/or install a custom
java.security.Policy
object. See the security
guide on policy files for more
information.
In general, when overriding security manager methods you should
place a call to the super.checkXXX
method at the point
where your overridden checkXXX
method would throw an
exception. For example:
public class MySecurityManager extends SecurityManager { public void checkRead(String file) { if (someCustomSecurityCheckFails()) { super.checkRead(file); } } }If your custom security check fails, then
super.checkRead
gets called. The default
implementation of checkRead
invokes
checkPermission
, which by default consults the
AccessController
. By invoking the
AccessController
, system code that has done an
AccessController.doPrivileged
before trying to read a
file will succeed in reading that file. All other code will be
subjected to the current policy in effect, and an access control
exception will be thrown if access to that file has not been
granted.
Note, there are some checkXXX
methods in which you
should not call super.checkXXX
methods when
overriding them. That is because the default implementation of
these methods may not be as strict as the policy you are
implementing in the overridden method. For example, the default
checkAccess(ThreadGroup g)
method only protects the
system thread group. If you intend to protect threads in distinct
thread groups from each other (for example applet thread groups),
then you would not want to call super.checkAccess
at
the point you would normally throw a security exception, as that
would defeat the purpose of your customized check. Instead, you
could place a call to super.checkAccess
as the first
statement in your overridden method.
For example:
public class AppletSecurityManager extends SecurityManager { public void checkAccess(ThreadGroup g) { // a call to super will throw an exception if someone // is trying to modify the system thread group super.checkAccess(g); ... // now perform checks based on which applet thread group // the current caller is in to see if they can modify thread group g. ... }
We describe how to override each method in the following section.
java.lang.SecurityManager
methods in the JDK and
provides suggestions regarding any overrides you may wish to make.
Please see the Java documentation for the
SecurityManager
class for more information on these
methods.
This field has been deprecated, and any uses of this field
within the JDK itself have been removed. Instead of using inCheck,
you should use checkPermission
along with
doPrivileged
.
This method has also been deprecated.
The constructor has been modified to allow multiple
SecurityManagers to be created, assuming the caller has the
RuntimePermission("createSecurityManager")
permission.
No changes. This call can be used to emulate the 1.1 behavior of
the methods that have been changed in the JDK (
currentClassLoader
, currentLoadedClass
,
classLoaderDepth
, inClassLoader
).
The typical use of this method in JDK 1.1-style security
managers was to see if there was a class loader on the stack, and
if not, treat the code as "trusted" and allow it to do anything.
This method has been modified in the JDK to allow trusted JDK code
(actually any code granted
java.security.AllPermission
) that calls
doPrivileged
to be treated as trusted by 1.1-style
security managers. It has also been modified to skip system class
loaders. A system class loader is defined as being a class loader
that is equal to the system class loader (as returned by
ClassLoader.getSystemClassLoader) or one of its ancestors.
This method will return null
in the following three
cases:
java.security.AllPermission
does not result in
a SecurityException.This method has been deprecated. Use
checkPermission
instead.
This method has been modified in the same fashion as
currentClassLoader
, and will return null
if the current security context has been granted
AllPermission
or all the methods on the stack (up to
the first privileged caller, if any) are from classes defined using
the system class loader or one of its ancestors.
This method has been deprecated. Use
checkPermission
instead.
No changes in behavior. This method has been deprecated. Use
checkPermission
instead.
This method has been modified in the same fashion as
currentClassLoader
, and will return -1
if
the current security context has been granted
AllPermission
or all the methods on the stack (up to
the first privileged caller, if any) are from classes defined using
the system class loader or one of its ancestors.
This method has been deprecated. Use
checkPermission
instead.
No changes in behavior. This method has been deprecated. Use
checkPermission
instead.
This method returns true if currentClassLoader
returns a non-null class loader, so it follows the same semantics
that currentClassLoader
does.
This method has been deprecated. Use
checkPermission
instead.
This method returns a
java.security.AccessControlContext
object that is
created with a call to
java.security.AccessController.getContext
. In JDK1.1
it returned null
by default.
This method is new in the JDK. It calls
java.security.AccessController.checkPermission
with
the given permission. Internally, the JDK always calls
SecurityManager.checkPermission
instead of calling the
AccessController
directly. This allows people to
override this method to provide additional functionality such as
auditing and/or GUI dialogs.
This method is new in the JDK. If context
is an
instance of AccessControlContext
then the
AccessControlContext.checkPermission
method will be
invoked on the given context with the specified permission.
If context
is not an instance of
AccessControlContext
then a
SecurityException
is thrown.
This method has been modified to call
checkPermission
with the
RuntimePermission("createClassLoader")
permission.
If this method is overridden, then a call to
super.checkCreateClassLoader
should be made at the
point the overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkCreateClassLoader() { if (someCustomSecurityCheckFails()) { super.checkCreateClassLoader(); } } }
If the thread argument is a system thread (belongs to the thread
group with a null
parent) then this method calls
checkPermission
with the
RuntimePermission("modifyThread")
permission.
Applications that want a stricter policy should override this method.
If this method is overridden, then
super.checkAccess
should be called by the first
statement in the overridden method, or the equivalent security
check should be placed in the overridden method.
If this method is overridden, the method that overrides it
should additionally check to see if the calling thread has the
RuntimePermission("modifyThread")
permission, and if
so, return silently. This is to ensure that code granted that
permission (such as the JDK itself) is allowed to manipulate any
thread.
For example:
public class MySecurityManager extends SecurityManager { public void checkAccess(Thread t) { // a call to super will throw an exception if someone // is trying to modify a system thread super.checkAccess(t); ... if (someCustomSecurityCheckForOtherThreadsFails()) { // if the check fails, instead of throwing an exception, // call checkPermission, which will throw an exception // if need be checkPermission(new RuntimePermission("modifyThread")); } ... } }
If the thread group argument is the system thread group (has a
null
parent) then this method calls
checkPermission
with the
RuntimePermission("modifyThreadGroup")
permission.
Applications that want a stricter policy should override this method.
If this method is overridden, then
super.checkAccess
should be called by the first
statement in the overridden method, or the equivalent security
check should be placed in the overridden method.
If this method is overridden, the method that overrides it
should additionally check to see if the caller has the
RuntimePermission("modifyThreadGroup")
permission, and
if so, return silently. This is to ensure that code granted that
permission (such as the JDK itself) is allowed to manipulate any
thread group.
For example:
public class MySecurityManager extends SecurityManager { public void checkAccess(ThreadGroup g) { // a call to super will throw an exception if someone // is trying to modify the system thread group super.checkAccess(g); ... if (someCustomSecurityCheckForOtherThreadGroupsFails()) { // if the check fails, instead of throwing an exception, // call checkPermission, which will throw an exception // if need be checkPermission(new RuntimePermission("modifyThreadGroup")); } ... } }
This method has been modified to call
checkPermission
with the
RuntimePermission("exitVM")
permission.
If this method is overridden, then a call to
super.checkExit
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkExit(int status) { if (someCustomSecurityCheckFails()) { super.checkExit(status); } } }
This method has been modified to call
checkPermission
with a FilePermission
. If
the cmd
is an absolute path (see
java.io.File.isAbsolute
) then it is passed as-is as
the target for the FilePermission
. If cmd
is not absolute, then the special target "<<ALL
FILES>>" is used. This target is used because it is difficult
to determine the actual path of the command that will be executed
on an individual platform due to things such as environment
variables, etc.
If this method is overridden, then a call to
super.checkExec
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkExec(String cmd) { if (someCustomSecurityCheckFails()) { super.checkExec(cmd); } } }
This method has been modified to call
checkPermission
with the
RuntimePermission("loadLibrary."+lib)
permission.
If this method is overridden, then a call to
super.checkLink
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkLink(String lib) { if (someCustomSecurityCheckFails()) { super.checkLink(lib); } } }
This method has been modified to call
checkPermission
with the
RuntimePermission("readFileDescriptor")
permission.
If this method is overridden, then a call to
super.checkRead
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkRead(FileDescriptor fd) { if (someCustomSecurityCheckFails()) { super.checkRead(fd); } } }
This method has been modified to call
checkPermission
with the
FilePermission(file,"read")
permission.
If this method is overridden, then a call to
super.checkRead
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkRead(String file) { if (someCustomSecurityCheckFails()) { super.checkRead(file); } } }
This method has been modified. If context
is an
instance of AccessControlContext
then the
AccessControlContext.checkPermission
method will be
invoked on the given context with the
FilePermission(file,"read")
permission.
If context
is not an instance of
AccessControlContext
then a
SecurityException
is thrown.
If this method is overridden, then a call to
super.checkRead
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkRead(String file, Object context) { if (someCustomSecurityCheckFails()) { super.checkRead(file, context); } } }
This method has been modified to call
checkPermission
with the
RuntimePermission("writeFileDescriptor")
permission.
If this method is overridden, then a call to
super.checkWrite
should be made at the point the
overridden method would normally throw an exception. For
Example:
public class MySecurityManager extends SecurityManager { public void checkWrite(FileDescriptor fd) { if (someCustomSecurityCheckFails()) { super.checkWrite(fd); } } }
This method has been modified to call
checkPermission
with the
FilePermission(file,"write")
permission.
If this method is overridden, then a call to
super.checkWrite
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkWrite(String file) { if (someCustomSecurityCheckFails()) { super.checkWrite(file); } } }
This method has been modified to call
checkPermission
with the
FilePermission(file,"delete")
permission.
If this method is overridden, then a call to
super.checkDelete
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkDelete(String file) { if (someCustomSecurityCheckFails()) { super.checkDelete(file); } } }
This method has been modified to call
checkPermission
with the
SocketPermission(host+":"+port,"connect")
permission
if the port is not equal to -1. If the port is equal to -1, then it
calls checkPermission
with the
SocketPermission(host,"resolve")
permission.
This behavior is consistent with JDK 1.1, where a port equal to -1 indicates that an IP address lookup is being performed.
If this method is overridden, then a call to
super.checkConnect
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkConnect(String host, int port) { if (someCustomSecurityCheckFails()) { super.checkConnect(host, port); } } }
This method has been modified. If context
is an
instance of AccessControlContext
then the
AccessControlContext.checkPermission
method will be
invoked on the given context with the
SocketPermission(host+":"+port,"connect")
permission
if the port is not equal to -1. If the port is equal to -1, then it
calls checkPermission
with the
SocketPermission(host,"resolve")
permission.
If context
is not an instance of
AccessControlContext
then a
SecurityException
is thrown.
If this method is overridden, then a call to
super.checkConnect
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkConnect(String host, int port, Object context) { if (someCustomSecurityCheckFails()) { super.checkConnect(host, port, context); } } }
This method has been modified. If port is not 0, it calls
checkPermission
with the
SocketPermission("localhost:"+port,"listen")
. If port
is zero, it calls checkPermission
with
SocketPermission("localhost:1024-","listen").
If this method is overridden, then a call to
super.checkListen
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkListen(int port) { if (someCustomSecurityCheckFails()) { super.checkListen(port); } } }
This method has been modified to call
checkPermission
with the
SocketPermission(host+":"+port,"accept")
permission.
If this method is overridden, then a call to
super.checkAccept
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkAccept(String host, int port) { if (someCustomSecurityCheckFails()) { super.checkAccept(host, port); } } }
This method has been modified to call
checkPermission
with the
SocketPermission(maddr.getHostAddress(),"accept,connect")
permission.
If this method is overridden, then a call to
super.checkMulticast
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkMultiCast(InetAddress maddr) { if (someCustomSecurityCheckFails()) { super.checkMultiCast(maddr); } } }
This method has been modified to call
checkPermission
with the
SocketPermission(maddr.getHostAddress(),"accept,connect")
permission.
If this method is overridden, then a call to
super.checkMulticast
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkMultiCast(InetAddress maddr, byte ttl) { if (someCustomSecurityCheckFails()) { super.checkMultiCast(maddr, ttl); } } }
This method has been modified to call
checkPermission
with the PropertyPermission("*",
"read,write")
permission.
If this method is overridden, then a call to
super.checkPropertiesAccess
should be made at the
point the overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkPropertiesAccess() { if (someCustomSecurityCheckFails()) { super.checkPropertiesAccess(); } } }
This method has been modified to call
checkPermission
with the PropertyPermission(key,
"read")
permission.
If this method is overridden, then a call to
super.checkPropertyAccess
should be made at the point
the overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkPropertyAccess(String key) { if (someCustomSecurityCheckFails()) { super.checkPropertiesAccess(key); } } }
This method has been modified to call
checkPermission
with the
AWTPermission("showWindowWithoutWarningBanner")
permission, and returns true if an SecurityException is not thrown,
otherwise it returns false.
If this method is overridden, then a call to
super.checkTopLevelWindow
should be made at the point
the overridden method would normally return false, and the value of
super.checkTopLevelWindow
should be returned. For
example:
public class MySecurityManager extends SecurityManager { public void checkTopLevelWindow(Object window) { if (someCustomSecurityCheckFails()) { return super.checkTopLevelWindow(window); } else { return true; } } }
This method has been modified to call
checkPermission
with the
RuntimePermission("queuePrintJob")
permission.
If this method is overridden, then a call to
super.checkPrintJobAccess
should be made at the point
the overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkPrintJobAccess() { if (someCustomSecurityCheckFails()) { super.checkPrintJobAccess(); } } }
This method has been modified to call
checkPermission
with the
AWTPermission("accessClipboard")
permission.
If this method is overridden, then a call to
super.checkSystemClipboardAccess
should be made at the
point the overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkSystemClipboardAccess() { if (someCustomSecurityCheckFails()) { super.checkSystemClipboardAccess(); } } }
This method has been modified to call
checkPermission
with the
AWTPermission("accessEventQueue")
permission.
If this method is overridden, then a call to
super.checkAwtEventQueueAccess
should be made at the
point the overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkAwtEventQueueAccess() { if (someCustomSecurityCheckFails()) { super.checkAwtEventQueueAccess(); } } }
This method has been modified. It first gets a list of
restricted packages by obtaining a comma-separated list from a call
to
java.security.Security.getProperty("package.access")
,
and checks to see if pkg
starts with or equals any of
the restricted packages. If it does, then
checkPermission
gets called with the
RuntimePermission("accessClassInPackage."+pkg)
permission.
If this method is overridden, then
super.checkPackageAccess
should be called as the first
line in the overridden method. For example:
public class MySecurityManager extends SecurityManager { public void checkPackageAccess(String pkg) { super.checkPackageAccess(pkg); ... someCustomSecurityCheck(); ... } }
This method has been modified. It first gets a list of
restricted packages by obtaining a comma-separated list from a call
to
java.security.Security.getProperty("package.definition")
,
and checks to see if pkg
starts with or equals any of
the restricted packages. If it does, then
checkPermission
gets called with the
RuntimePermission("defineClassInPackage."+pkg)
permission.
If this method is overridden, then
super.checkPackageDefinition
should be called as the
first line in the overridden method. For example:
public class MySecurityManager extends SecurityManager { public void checkPackageDefinition(String pkg) { super.checkPackageDefinition(pkg); ... someCustomSecurityCheck(); ... } }
This method has been modified to call
checkPermission
with the
RuntimePermission("setFactory")
permission.
If this method is overridden, then a call to
super.checkSetFactory
should be made at the point the
overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkSetFactory() { if (someCustomSecurityCheckFails()) { super.checkSetFactory(); } } }
This method has been modified. The default policy is to allow
access to PUBLIC members, as well as access to classes that have
the same class loader as the caller. In all other cases call
checkPermission
with the
RuntimePermission("accessDeclaredMembers")
permission.
If this method is overridden, then a call to
super.checkMemberAccess
cannot be made, as the default
implementation of checkMemberAccess
relies on the code
being checked being at a stack depth of 4. For example:
someCaller[3] java.lang.Class.someReflectionAPI [2] java.lang.Class.checkMemberAccess [1] SecurityManager.checkMemberAccess [0]In order to emulate this behavior, you would need to call
getClassContext
, and examine the class loader of the
class at index 3, just as the default
checkMemberAccess
method does:
if (which != Member.PUBLIC) { Class stack[] = getClassContext(); /* * stack depth of 4 should be the caller of one of the * methods in java.lang.Class that invoke checkMember * access. The stack should look like: * * someCaller [3] * java.lang.Class.someReflectionAPI [2] * java.lang.Class.checkMemberAccess [1] * MySecurityManager.checkMemberAccess [0] * */ if ((stack.length<4) || (stack[3].getClassLoader() != clazz.getClassLoader())) { if (checkMemberAccessPermission == null) checkMemberAccessPermission = new RuntimePermission("accessDeclaredMembers"); checkPermission(checkMemberAccessPermission); } }
This is the only security manager method in the JDK that is still based on a caller's depth. This is to allow a caller to reflect on classes from the same class loader it came from.
This method has been modified to create a
SecurityPermission
object for the given permission
target name and calls checkPermission
with it.
If this method is overridden, then a call to
super.checkSecurityAccess
should be made at the point
the overridden method would normally throw an exception. For
example:
public class MySecurityManager extends SecurityManager { public void checkSecurityAccess(String target) { if (someCustomSecurityCheckFails()) { super.checkSecurityAccess(target); } } }
This method has not been changed.

Clock Demo Plugin
The source code of this plugin is available here .
This example demonstrates how a plugin can add a custom ToolStrip to the toolbar.
UserControl in a ToolStrip
Using the designer in Visual Studio, we have created a
custom control,
a child of
UserControl,
that we want to appear on the toolbar. This control is just a panel with a few labels to display
the date, time, and the UTC/Local switch. The control is located in the
Clock.cs
unit.
The plugin implements only one interface,
IPlugin.
Implementation is similar to that described in
Creating Your First Plugin,
the only important difference is the ToolStrip
property: it is no longer null
, we initialize
it with an instance of the
ToolStrip
class
public ToolStrip ToolStrip { get; } = new ToolStrip();
and add our Clock
panel to it:
private readonly Clock clock = new Clock();
...
ToolStrip.Items.Add(new ToolStripControlHost(clock));
By default, the toolstrips are aligned to the left of the toolbar. If the user chooses
to align our clock to the right, we set the RightToLeft
property of the ToolStrip
to Yes
:
ToolStrip.RightToLeft = settings.DockToRight ? RightToLeft.Yes : RightToLeft.No;
Standard Controls in a ToolStrip
If we wanted to add one or more standard controls, such as buttons, to the toolstrip,
we would not have to use the designer, we could create that control in code instead.
Also, we could create the ToolStrip
in the constructor instead of using an initializer.
Here is how
it is done in the AGC plugin. The ToolStrip
property
has both a getter and a setter so that it can be assigned to:
public ToolStrip ToolStrip { get; private set; }
In the plugin constructor, a button is created, its properties are set, and finally a ToolStrip is created with the button in it:
button = new ToolStripButton()
{
AutoSize = false,
Size = new Size(30, 28),
ImageTransparentColor = Color.White,
Image = Properties.Resources.AgcImage,
CheckOnClick = true,
Checked = settings.Enabled
};
button.Click += Button_Click;
ToolStrip = new ToolStrip(button);

java.lang.Object org.smslib.smsserver.interfaces.Interface<T>
public class Interface<T>
The base class of all implemented SMSServer interfaces.
An SMSServer interface can be thought of as a message producer or a message consumer.
SMSServer comes with a couple of ready-made interfaces. If you wish to extend SMSServer with new interface functionality, create your own interface by implementing the current class.

Broadcast Plugin Readme
Overview
The broadcast plugin broadcasts messages to all users in the system or to specific groups. It's
primarily useful for sending announcements or notifications.
Installation
Copy broadcast.jar into the plugins directory of your Openfire installation. The
plugin will then be automatically deployed. To upgrade to a new version, copy the new
broadcast.jar file over the existing file.
Configuration
The broadcast plugin is configured via Openfire system properties. These can
be configured under Server/Server Manager/System Properties:
- plugin.broadcast.serviceName -- the name of the broadcast service. If no value
is set, the default is "broadcast".
- plugin.broadcast.disableGroupPermissions -- true to allow any user to
broadcast a message to a group. When false, only group members or administrators can
broadcast messages to a group. The default value is false.
- plugin.broadcast.groupMembersAllowed -- true to also allow group members
to send broadcast messages to groups they belong to. When false, only administrators can
send broadcast messages to a group. The default value is true. Note that the property value
of plugin.broadcast.disableGroupPermissions can effectively override this value
by letting anyone send broadcast messages to groups.
- plugin.broadcast.allowedUsers -- the comma-delimitted list of users allowed
to broadcast messages to all connected users at once. When this property isn't set,
anyone is allowed to broadcast messages to all users. Users should be specified by their
bare JID (e.g<EMAIL_ADDRESS>- plugin.broadcast.all2offline -- true to deliver broadcast messages sent
to<EMAIL_ADDRESS>to online and offline users. When false or not
set only online users get the messages as described below.
- plugin.broadcast.messagePrefix -- Add a prefix for all broadcast
messages. Set this to "(broadcast)" to prepend "(broadcast) ".
Using the Plugin
To send a broadcast message, send a message to<EMAIL_ADDRESS>or
<EMAIL_ADDRESS>For example, if your server is called foo and the
default service name is being used, a message to<EMAIL_ADDRESS>would be broadcast to
all users connected to the server. For the group staff, a message to<EMAIL_ADDRESS>would
be sent to all users in the group staff that are currently online or offline.
Note: for maximum compatability between group implementations, it's recommended that you use
lower-case group names in conjunction with the broadcast plugin.


--- layout: page weight: 0 title: CakePHP seo: title: Send Email with CakePHP & SendGrid description: View instructions on how to easily send email with CakePHP using SendGrid, by setting up your views and controller. navigation: show: true ---
CakePHP comes with an email library that already supports SMTP. For more information check out the CakePHP documentation page. This example shows how to send an email with both HTML and text bodies.
In app/views/layouts/ you need to define the layout of your text and HTML emails:
{% codeblock %}
email/
html/
default.ctp
text/
default.ctp
{% endcodeblock %}
In app/views/layouts/email/text/default.ctp add:
{% codeblock lang:php %}
{% endcodeblock %}
and in app/views/layouts/email/html/default.ctp add:
{% codeblock lang:php %}
{% endcodeblock %}
Then create the template for your emails. In this example we created templates for a registration email with the following structure:
{% codeblock %}
app/
views/
elements/
email/
text/
registration.ctp
html/
registration.ctp
{% endcodeblock %}
In app/views/elements/email/text/registration.ctp add:
{% codeblock lang:php %}
Dear ,
Thank you for registering. Please go to http://domain.com to finish your registration.
{% endcodeblock %}
and in app/views/layouts/email/html/default.ctp add:
{% codeblock lang:php %}
Dear ,
Thank you for registering. Please go to here to finish your registration.
{% endcodeblock %}
In your controller enable the email component:
{% codeblock lang:php %}
{% endcodeblock %}
Then anywhere in your controller you can do something like the following to send an email:
{% codeblock lang:php %}
Email->smtpOptions = array(
'port'=>'587',
'timeout'=>'30',
'host' => 'smtp.sendgrid.net',
'username'=>'sendgrid_username',
'password'=>'sendgrid_password',
'client' => 'yourdomain.com'
);
$this->Email->delivery = 'smtp';
$this->Email->from = 'Your Name ';
$this->Email->to = 'Recipient Name ';
$this->set('name', 'Recipient Name');
$this->Email->subject = 'This is a subject';
$this->Email->template = 'registration';
$this->Email->sendAs = 'both';
$this->Email->send();
?>
{% endcodeblock %}

If you have time, enjoy this essay by the science-fiction author Neal Stephenson.
Editing file is most of the job, so please also consider using a descent editor. The author uses and recommends GNU Emacs, because it simply rocks!
1 Getting Help
man <command>
Quit by pressing q
.
man ls man cd man mkdir
2 The TAB
key
Whenever entering (long) paths or file names, the TAB
key comes in
very handy, because it autocompletes the end or proposes how to
complete. Autocompletion is so handy…
Imagine you want to enter in this fictional directory, by typing all these components:
cd /data/home/alturi/project/long-filename.ext
Prone error !! Instead, the TAB
key is magic, try:
cd /d[TAB]ata/h[TAB]ome/al[TAB]turi/pro[TAB]ject/lo[TAB]ng-filename.ext
When you type ambiguous character (e.g., pro
should point to your
fictional folder project/
or product/
), the completion does not
work. In that case, hit TAB
twice to view all the possible matches and
then type a few more characters.
3 History of the command line
Just use ARROW UP
and DOWN
to navigate through the history.
List all the recent history:
history
4 Where I am
pwd
Show the absolute path.
5 Create new directory
mkdir <name>
You can also create the directory and couple of subfolders:
mkdir -p my-project/this/that
6 Change directory
cd <directory>
For example, go to the previous created folder, and verify you are in:
cd my-project/this/that pwd
Go at one level up (parent directory) and verify again:
cd .. pwd
Go to the folder that/
then go at two levels up:
cd that/ pwd cd ../.. pwd
Note that:
cd
go to the $HOME
folder.
7 List the content of a directory
ls <directory>
and without any <directory>
name, list the current folder.
List all the files, even the hidden ones:
ls -a
List the files and sort them by reverse order of modified time:
ls -rt1
List the files with some useful information (permissions, owner, size etc.)
ls -l
List recursively through the subfolders:
ls -R
8 Read the content of a file
less <filename>
Quit with :q
.
9 Display the first N
lines (last N
lines)
head -nN <filename> tail -nN <filename>
For example, display the first 5 commands:
head -n5 ~/.bash_history
10 Clear the terminal window (just cosmetic)
clear
Nothing is erased, it is pure cosmetic by refreshing.
11 Copy file / directory
cp <source> <target>
For example, copy the history of the command lines and list the folder:
cp ~/.bash_history ~/my-history ls -rt1
After creating a new folder, copy the file into it:
cp my-history my-project/this/that ls my[TAB]-project/[TAB]this/[TAB]that/
Copy folders:
cp -R my-project my-project2 ls -R my-project2
12 Rename file / directory
mv <source> <target>
13 Remove file / directory
rm <filename> rm -fr <filename>
The option -f
means force. Be careful !!
14 Search files
find <dir> -name "<filename>" -type f
For example, list all the files with the extensions .fastq.gz
in the
current folder:
find . -name "*.fastq.gz" -type f -print
Find all Pearl files .pl
containing the occurence xls and print the line:
find . -type f -name "*.pl" -print | xargs grep -nH xls
15 Copy files / directory through the network
rsync -av --progress <source> <target>
For example, push local folder to server
toto.tata.univ-paris-diderot.fr
:
rsync -av --progress my-project username@toto.tata.univ-paris-diderot.fr:~/
Pull remote folder:
rsync -av --progress username@toto.tata.univ-paris-diderot.fr:~/my-project my-project2
Be careful with the trailing slash /
. Explanations later !
16 Check what is going on
htop
17 Kill active process
CONTROL c
Or you can find the process number with:
ps -fe | less
and identify the guilty.

Re: Not able to upload data to emoncms, please help
I am waiting for somebody reply please ..
Re: Not able to upload data to emoncms, please help
I can immediately see two things that are wrong.
1. You have <......> around your APIkey (and I have obscured it, because with it ANYONE can send data to your account.
2. The json format is wrong - a '}' in the wrong place. Look at Input API Help in emoncms, the correct format is:
json={power:200}
What you are sending is: ...?apikey=<6834396c9feb5********7d973b2d74f>&json={power}:200}
What you should be sending is
... ?apikey=6834396c9feb5********7d973b2d74f&json={power:200}
There might be other problems too that I have not seen.
Re: Not able to upload data to emoncms, please help
Dear Robert thankyou for your reply i have checked and correct it ..still not working .my arduino is getting DHCP ip from Router very well, can you suggest me what other problem might be.
client.print("GET/http://emoncms.org/input/post.json?json={power:200}&apikey=xxxxxx6c9feb5718e21637d973bxxxxx");
thankyou

Re: Not able to upload data to emoncms, please help
Please have some patience. You are not the only person on this website, and we cannot answer your questions immediately. And please READ the notice at the top right of your screen that says "Read this before posting".
Re: Not able to upload data to emoncms, please help
Have you searched the forums for a similar problem, or for someone who is successfully using a sketch derived from the same place as yours?
You could compare yours with this one: http://openenergymonitor.org/emon/node/11499 The problem there was a simple copy-and-paste error that affected the content that was sent. How the data was being sent was correct, so it is a good one to look at.
Re: Not able to upload data to emoncms, please help
HI Robert
Good morning.
actually i haven't seen my post at forum .that's why i try again and again that's why post get double .hope you understand.
thankyou for the web link i will compare mine sketch with this ,let's hope this time i get sucuess.
thankyou

This will create an instance of the requested physics simulation. Phaser.Physics.Arcade is running by default, but all others need activating directly.
You can start the following physics systems:
Phaser.Physics.P2JS - A full-body advanced physics system by Stefan Hedman. Phaser.Physics.NINJA - A port of Metanet Softwares N+ physics system. Phaser.Physics.BOX2D - A commercial Phaser Plugin (see http://phaser.io)
Both Ninja Physics and Box2D require their respective plugins to be loaded before you can start them. They are not bundled into the core Phaser library.
If the physics world has already been created (i.e. in another state in your game) then calling startSystem will reset the physics world, not re-create it. If you need to start them again from their constructors then set Phaser.Physics.p2 (or whichever system you want to recreate) to null
before calling startSystem

React Components
Vlad the ImpalerComponents are the smallest, yet most fundamental part of React. They’re similar, in concepts, to things like widgets and modules. React defines itself as a library for building user interfaces. As such, when you think of a user interface you want to build (with React), you need to think of it in terms of the smallest possible components that you can define. These components include code which defines how DOM elements are created and how users can interact with them. Components can be defined purely in JavaScript or they can be defined in a superset (or extended variation) of JavaScript called JSX. If you decide to use JSX for your component definitions, you may also need a compiler application, but we’ll get to that in a minute.
We’re going to be referring to pure JavaScript as JS and the React version of JavaScript as JSX.
You can find the accompanying source-code, for this tutorial, at: https://github.com/formativ/tutorial-react-components.
Please post any errors you find, or questions you have as comments on this article or as issues on GitHub.
Thanks to Pete Hunt for helping to improve this!Embedded HTML
If you’ve been developing websites for a while, you may have flinched when I spoke about using HTML within your JavaScript. For the longest time, a development paradigm has existed which says that you should split HTML and JavaScript. Words like unobtrusive have been repurposed to express this kind of separation. That is exactly how I felt, until I started working with React. The reason this paradigm exists is to decrease coupling (how much things depend on each other) and increase cohesion (how well different things work together). So we have created an environment in which we try our best to make HTML (and templates) as free of logic as possible. We then need to attach behaviour to this in the form of external scripts. There are trade-offs with this approach to doing things. For starters, it takes more effort trying to keep these two things separate. There are many template engines and languages. There are also many template parsers to handle them all. And yet these languages (with the exception of HTML) still seem to include a modicum of logical operations… Additionally, when we need to modify the contents of a web page, via JavaScript, we have to know about HTML and/or templates. How else can we know what to display and where to display it? We could load external templates, via additional HTTP requests, but how would we know where to put it without some knowledge of the DOM? We could load templates embedded within special script tags, but we would first need to fetch the contents of those script tags. This brings us to the biggest problem with the separation of HTML and JavaScript: The only way we can get elements to attach behaviour to, and read data from, is by knowing about HTML elements in the document. Libraries like jQuery are built around the idea that HTML elements are only a CSS selector away from JavaScript.
