Method Detail

handleInvocation

public void handleInvocation(EJBClientInvocationContext context)
                      throws Exception

Description copied from interface: EJBClientInterceptor

Handle the invocation. Implementations may short-circuit the invocation by throwing an exception. This method should process any per-interceptor state and call EJBClientInvocationContext.sendRequest().

Specified by:

handleInvocation in interface EJBClientInterceptor

Parameters:

context - the invocation context

Throws:

Exception - if an invocation error occurs

handleSessionCreation

public SessionID handleSessionCreation(EJBSessionCreationInvocationContext context)
                                throws Exception

Description copied from interface: EJBClientInterceptor

Optionally handle a session creation invocation. Explicit session creation is always a blocking operation. The default operation forwards to the next interceptor in the chain.

Specified by:

handleSessionCreation in interface EJBClientInterceptor

Parameters:

context - the session creation invocation context (not null)

Returns:

the stateful EJB locator (must not be null)

Throws:

Exception - if an invocation error occurred

handleInvocationResult

public Object handleInvocationResult(EJBClientInvocationContext context)
                              throws Exception

Description copied from interface: EJBClientInterceptor

Handle the invocation result. The implementation should generally call EJBClientInvocationContext.getResult() immediately and perform any post-invocation cleanup task in a finally block.

Specified by:

handleInvocationResult in interface EJBClientInterceptor

Parameters:

context - the invocation context

Returns:

the invocation result, if any

Throws:

Exception - if an invocation error occurred
