Hi James. Not sure what you are asking for? The InvocationRequest.getSessionId() comes from when a remoting Client is created and set on the InvocationRequest when making an invocation (although user could set their own session id via the Client's setter method). As for a session id being associated with the InvokerCallbackHandler, there really isn't one, so this is throwing me. Are you saying you want one so know from which client the callback handler originally came from? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021487#...
