Class SubjectSecurity

java.lang.Object
oracle.security.jps.runtime.SubjectSecurity

public abstract class SubjectSecurity

extends java.lang.Object

This class defines APIs to create ActionExecutor for asserted users and for authenticated subjects and to execute PrivilegedAction or PrivilegedExceptionAction with a user subject in the container security context and JDK AccessControlContext.

It provides a factory API to create platform-dependent SubjectSecurity instances based on the runtime platform type.

Some methods of this class are protected by code permission oracle.security.jps.JpsPermission with name "IdentityAssertion" and action "execute". Application code sources need to be granted the above permission when invoking these APIs.

Method Summary

abstract <T> T	executeAs(javax.security.auth.Subject subject, java.security.PrivilegedAction<T> action) Executes the PrivilegedAction as the specified subject in the platform security context and JDK AccessControlContext.
abstract <T> T	executeAs(javax.security.auth.Subject subject, java.security.PrivilegedExceptionAction<T> action) Executes the PrivilegedExceptionAction as the specified subject in the platform security context and JDK AccessControlContext.
abstract ActionExecutor	getActionExecutor(javax.security.auth.callback.CallbackHandler handler) Gets an ActionExecutor for the user specified by CallbackHandler.
abstract ActionExecutor	getActionExecutor(java.lang.String userName) Gets an ActionExecutor for the specified user name.
abstract ActionExecutor	getActionExecutor(javax.security.auth.Subject subject) Gets an ActionExecutor for the specified subject.
abstract ActionExecutor	getAnonymousActionExecutor() Gets an ActionExecutor with anonymous user security contexts.
static SubjectSecurity	getInstance() Gets an instance of SubjectSecurity based on the runtime platform type.

Method Detail

getInstance

public static SubjectSecurity getInstance()
                                   throws JpsException

Gets an instance of SubjectSecurity based on the runtime platform type.

A SubjectSecurity instance with JDK AccessControlContext will be returned if it's not running in any specific JEE containers, e.g. Weblogic, Websphere and etc.

Returns:

an instance of SubjectSecurity

Throws:

JpsException - if fails to create a platform dependent SubjectSecurity instance

getActionExecutor

public abstract ActionExecutor getActionExecutor(java.lang.String userName)
                                          throws AssertionException

Gets an ActionExecutor for the specified user name.

A SubjectSecurity implementation should first assert the specified user name against the identity store, and create an ActionExecutor for the asserted user.

This method is protected by code permission oracle.security.jps.JpsPermission with name "IdentityAssertion" and action "execute". The application code sources need to be granted the above permission when invoking this method.

It should raise AssertionException if the user name fails to be asserted.

Parameters:

userName - the user name to be asserted

Returns:

an ActionExecutor associated with the asserted user

Throws:

AssertionException - if the specified user name fails to be asserted

getActionExecutor

public abstract ActionExecutor getActionExecutor(javax.security.auth.callback.CallbackHandler handler)
                                          throws AssertionException

Gets an ActionExecutor for the user specified by CallbackHandler.

A SubjectSecurity implementation should first assert the specified user name against the identity store, and create an ActionExecutor for the asserted user.

This method is protected by code permission oracle.security.jps.JpsPermission with name "IdentityAssertion" and action "execute". The application code sources need to be granted the above permission when invoking this method.

It should raise AssertionException if the user name fails to be asserted.

Parameters:

handler - can handle IdentityCallback and TenantCallbak for the user to be asserted

Returns:

an ActionExecutor associated with the asserted user

Throws:

AssertionException - if the specified user name fails to be asserted

getActionExecutor

public abstract ActionExecutor getActionExecutor(javax.security.auth.Subject subject)

Gets an ActionExecutor for the specified subject.

The given subject must be a security platform specific subject.

Parameters:

subject - the security platform specific subject to be used for this executor

Returns:

an ActionExecutor associated with the specified subject

getAnonymousActionExecutor

public abstract ActionExecutor getAnonymousActionExecutor()
                                                   throws JpsException

Gets an ActionExecutor with anonymous user security contexts.

The default implementation of SubjectSecurity with JDK AccessControlContext will associate JDK AccessControlContext with JPS anonymous subject.

Returns:

an ActionExecutor with anonymous user security contexts

Throws:

JpsException - if anonymous security contexts fails to be created

executeAs

public abstract <T> T executeAs(javax.security.auth.Subject subject,
                                java.security.PrivilegedAction<T> action)

Executes the PrivilegedAction as the specified subject in the platform security context and JDK AccessControlContext.

The given subject must be a security platform specific subject.

Parameters:

subject - a security platform specific subject

action - an instance of PrivilegedAction

Returns:

the value returned by the PrivilegedAction.run method

executeAs

public abstract <T> T executeAs(javax.security.auth.Subject subject,
                                java.security.PrivilegedExceptionAction<T> action)
                     throws java.security.PrivilegedActionException

Executes the PrivilegedExceptionAction as the specified subject in the platform security context and JDK AccessControlContext.

The given subject must be a security platform specific subject.

Parameters:

subject - a security platform specific subject

action - an instance of PrivilegedExceptionAction

Returns:

the value returned by the PrivilegedExceptionAction.run method

Throws:

java.security.PrivilegedActionException - if the PrivilegedExceptionAction.run method throws a checked exception
