Subject emulate synchronous response, need suggestion
Date Sun, 08 Jan 2012 13:03:39 GMT

I emulate synchronous HTTP communication(that is requirement):

1. I send http request to the Servlet from a browser.

2. Servlet opens connection to the remote queue/server and send the message

At the same time new Temporary queue opened to accept reply messages for
each new HttpSession.
(such a way 1 client with 1 session has 1 queue for all replies to him)

3. Server(the side, that keeps remote queue) returns reply to the temporary
queue of the client.

4. Here is the problem:
I can put each request thread in 1 sec. loop for say 10 seconds , trying to
filter replies from the TEMP queue and if correlation ID, sent in response
matches, consider, that I have the response and so stop looping and send the
response to the browser.

But this is not efficient, if simultaneously 300 clients send me requests, I
should keep 300 threads busy in accepting replies, while most of the work is
in unproductive looping.

How can I release the request thread and in the same time keep user in wait
without response?
Is there some way to achieve that?

Thanks a lot.
