I dug in the source and noticed that the response headers are not
"automatically reflected back into the stub list". This seems
to be a change. How would I get the response headers then?
Why was this changed from RC1?

Subject: RE: Do server side handlers really work?
Thank I found the responseFlow mapping last night, now it gets called on both the
request and response. However, I do Not see the SOAP header on the client side.
In the code below I should see the header set on ther server side in "h".?
CountServiceLocator locator = new CountServiceLocator();
Count count = locator.getCount(new
URL("http://localhost:8080/axis/services/Count";));
org.apache.axis.client.Stub stub = (Stub) count;
stub.setTimeout(45000); //in milliseconds
stub.setMaintainSession(true); // Invoke Service
count.add(1);
SOAPHeaderElement[] h = stub.getHeaders();

Subject: Re: So server side handlers really work?
Ross - the documentation states that SimpleSessionHandler needs to be mapped into both
the request and response flows on the server. Because you haven't mapped the handler
into the response flow, the doServer code for when context.getPastPivot() == false
will never be executed which is critical for the proper operation of the handler.
Additionally, you need to map a corresponding SimpleSession handler in the client.
\test\session\TestSimpleSession demonstrates and example client and server deployment.
here's the information provided in SimpleSessionHandler.java:
* <p>Essentially, you install it on both the request and response chains of
* your service, on both the client and the server side.</p>
*
* <p>ON THE SERVER:</p>
* <ul>
* <li>The REQUEST is checked for a session ID header. If present, we
* look up the correct SimpleSession. If not, we create a new session.
* In either case, we install the session into the MessageContext, and
* put its ID in the SESSION_ID property.
* <li>The RESPONSE gets a session ID header tacked on, assuming we found a
* SESSION_ID property in the MessageContext.
* </ul>
* <p>ON THE CLIENT:</p>
* <ul>
* <li>The RESPONSE messages are checked for session ID headers. If present,
* we pull the ID out and insert it into an option in the AxisClient.
* This works because a given Call object is associated with a single
* AxisClient. However, we might want to find a way to put it into the
* Call object itself, which would make a little more sense. This would
* mean being able to get to the Call from the MC, i.e. adding a getCall()
* API (which would only work on the client side)....
* <li>When REQUESTS are generated, we look to see if an ID option is present
* in the AxisClient associated with the MessageContext. If so, we
* insert a session ID header with the appropriate ID.
* </ul>
