Method Detail

handleInvocation

void handleInvocation(EJBClientInvocationContext context)
                      throws Exception

Handle the invocation. Implementations may short-circuit the invocation by throwing an exception. This method should process any per-interceptor state and return.

Parameters:

context - the invocation context

Throws:

Exception - if an invocation error occurs

handleInvocationResult

Object handleInvocationResult(EJBClientInvocationContext context)
                              throws Exception

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

Parameters:

context - the invocation context

Returns:

the invocation result, if any

Throws:

Exception - if an invocation error occurred
