Class SecurityContext

java.lang.Object
  extended by javax.resource.spi.work.SecurityContext
All Implemented Interfaces:
java.io.Serializable, WorkContext

public abstract class SecurityContext
extends java.lang.Object
implements WorkContext

A standard WorkContext that allows a Work instance to propagate security related context information from an EIS to an application server.

This allows an EIS/resource adapter to flow-in security context information and execute a Work instance, and call methods on a MessageEndpoint interface, to effect message inflow, within that Work instance, in the context of an established identity.

A resource adapter indicates to the WorkManager, that a Work instance needs to be run in a specified security execution context by submitting a Work instance that implements WorkContextProvider interface and ensuring that the List of WorkContexts for that Work instance contains an instance of its subclass of Securitytext.

It should be noted however that when a resource adapter flows-in an identity to be used by the application server, the propagated identity may or may not belong to the application server's security domain.

There are therefore, two scenarios while a resource adapter propagates a security identity from an EIS to the application server:

Method Detail

getDescription

public java.lang.String getDescription()
Get the brief description of the role played by the WorkContext and any other related debugging information. This could be used by the WorkManager and the resource adapter for debugging purposes.

Specified by:
getDescription in interface WorkContext
Returns:
the associated description of the WorkContext

getName

public java.lang.String getName()
Get the associated name of the WorkContext. This could be used by the WorkManager and the resource adapter for debugging purposes.

Specified by:
getName in interface WorkContext
Returns:
the associated name of the WorkContext

setupSecurityContext

public abstract void setupSecurityContext(javax.security.auth.callback.CallbackHandler handler,
                                          javax.security.auth.Subject executionSubject,
                                          javax.security.auth.Subject serviceSubject)
The container calls this method to set up the security Context for the Work instance.

The handler argument must not be null, and the argument handler and the CallbackHandler passed to this method must support the following Callbacks defined in JSR 196: Java Authentication SPI for Containers specification:

The following Callbacks may be supported by the container.

A resource adapter might use the CallerPrincipalCallback "to set the container's representation of the caller principal. The CallbackHandler must establish the argument Principal as the caller principal associated with the invocation being processed by the container. When the argument Principal is null, the handler will establish the container's representation of the unauthenticated caller principal."

A resource adapter might use the GroupPrincipalCallback "to establish the container's representation of the corresponding group principals within the Subject. When a null value is passed to the groups argument, the handler will establish the container's representation of no group principals within the Subject. Otherwise, the handler's processing of this callback is additive, yielding the union (without duplicates) of the principals existing within the Subject, and those created with the names occurring within the argument array. The CallbackHandler will define the type of the created principals."

A resource adapter might use the PasswordValidationCallback "to employ the password validation facilities of its containing runtime."

The executionSubject argument must be non-null and it must not be read-only. It is expected that this method will populate this executionSubject with principals and credentials that would be flown into the application server.

The serviceSubject argument must be non-null and it must not be read-only. It represents the application server and it may be used by the Work implementation to retrieve Principals and credentials necessary to establish a connection to the EIS (in the cause of mutual-auth like scenarios). If the Subject is not null, the Work implementation may collect the server credentials, as necessary, by using the callback handler passed to them .

When this method is called, the method implementation

Parameters:
handler - A CallbackHandler provided by the WorkManager that supports the Callbacks described above
executionSubject - A Subject that represents the security identity that needs to be established as the context for the Work instance. It is used by the method implementation to store Principals and credentials that needs to be used as the security context of the Work instance.
serviceSubject - A Subject that represents the application server It may be used by the method implementation as the source of Principals or credentials to be used to validate a connection to the EIS. If the Subject is not null, the method implementation may add additional Principals or credentials (pertaining to the recipient of the service request) to the Subject. *
