Identify the Clients from Server in Pull Callback Jboss remo

[vasanth_java]

In Pull Callback method in JBoss Remoting, I am having one Server that will generate the callbacks automatically through a Thread without differentiating the clients. When trying to access by multiple clients simultaneously, all the clients getting the same callbacks. I came through the articles saying that to identify a client in JBoss Remoting, the session id of the invoking client is used. I got the session id by:

At the client side by

Client remotingClient = new Client(uriLocator, metadata);
String sessionId = RemotingClient.getSessionId();

At the server side by

public Object invoke(InvocationRequest invocation) throws Throwable
{
String sessionId = invocation.getSessionId();
}

Usually we pass the callbackhandler object of the client through addListener() method to server. But how I can link this session id with the corresponding callbackhandler of the client. I require this for giving back the callback to the handler. So I need a map between the sessionId and callbackhandler.
i.e how to identify/differentiate the clients from server in pull callback?

If I understand you correctly, you want to be able to identify the callback handler on the client from within the invocation handler on the server side. If this is what you are asking, then yes, this can be done. However, it requires a casting of the InvokerCallbackHandler added within the ServerInvocationHandler to ServerInvokerCallbackHandler, on which you can call getClientSessionId() to get the client id.

I have added a test case that demonstrates using two clients with a distinct callback handler each. The classes are:

org.jboss.test.remoting.callback.pull.CallbackTestServer
org.jboss.test.remoting.callback.pull.CallbackInvocationHandler
org.jboss.test.remoting.callback.pull.CallbackInvocationHandler

Will have to either checkout the remoting project or can browse the source at http://viewcvs.labs.jboss.com/cgi-bin/viewcvs.cgi/JBossRemoting/src/tests/org/jboss/test/remoting/callback/pull/
