There was some discussion last

There was some discussion last night regarding the use of JMS behind altRMI to

make asynchronous calls. Taking the idea further, I wondered if it might be

possible to implement asynchronous callbacks using temporary queues. So

requests that take a long time, but need to return a response to the user could

present a ‘please wait…’ message, or pop up an alert when the response has

arrived, without the client having to poll the server.

Some sample code I found here

looked a bit like this:

Queue tempQueue = qSession.createTemporaryQueue();

TextMessage request = qSession.createTextMessage();


QueueReceiver qReceiver = qSession.createReceiver(tmpQueue);

qReceiver.setMessageListener(new MyMessageListener(. . .));

Could be interesting, perhaps.
