Richard,
yeah, I had some basic questions about sessions a couple weeks ago, and
they got answered pretty well. You can check the list archives for the
thread "how to implement sessions, persistent objects, etc. ?". The way
you're implementing sessions, I'd guess the thing you're missing is a line
in the deploy.wsdd file that Stan Jordan pointed out. Here's the relevant
section:
<service name="StatefulService" provider="java:RPC">
<parameter name="className" value="StatefulService"/>
<parameter name="allowedMethods" value="*"/>
<parameter name="scope" value="session"/>
</service>
note the parameter "scope", which sets this service to have "session scope"
(i.e. it remembers session information across requests).
As Steve Loughran pointed out, since this method relies on cookies, it ties
your service to HTTP and to clients that understand cookies (not part of
the SOAP spec). It looks like the only alternative to using cookies is to
write all the session maintenance code yourself and store session info in a
database or application-scoped objects. That's what I'm looking into, and
if I get anything working I'll post an example.
