These tests will be junit, since they're testing MessageListenerServlet. =
 The trouble I've had in the past, and continue to have, is that I =
haven't been able to get the session cookie returned during my tests.

Here's a test I've worked on : http://pastie.org/1177995
Here's the output : http://pastie.org/1178030

This code shows 2 separate ways I've tried accessing the response =
headers.
1. Implementing ContentExchange.onResponseHeader.  My callback is never =
called, though my other onRequestComplete and onResponseComplete =
callbacks are.
2. Trying to use ContentExchange.getResponseFields().  The returned =
object is null.

I watched port 8080 in wireshark while my test was running, and I did =
see that the 'Set-Cookie' header was returned by the server.=20
http://skitch.com/alexdean/d2g2b/capturing-from-lo0-wireshark

I am able to send a POST to the servlet, and I do receive a response, =
but without the cookie I can't associate my later requests with the =
subscriptions I've created in the initial POST.

If anyone can see what I'm doing wrong, I'd really appreciate some tips =
or even a nudge in the right direction.  If I could get this working, I =
could write a test pretty easily to reproduce the issue we're currently =
seeing, and then verify the issue has been fixed.  I could also write =
tests for the previous patches I've submitted  for =
MessageListenerServlet.

thanks,
