Hello,
I am using JMS Transport with the caller being a session EJB and I would
like to use extended transactions within the bean (i.e. if web service call
and other operations should all succeed or all should get rolled back). The
code that I'm using from the bean method is very similar to how the call is
made in the JMS sample (except that I don't have the listener since that is
the server side of the web service). I'm finding that using
XAQueueConnectionFactory that when the bean method gets called for the
second time, I get an error message which basically says connection with the
given ID already exists. I'm wondering if the connection is somehow
remaining open? As in the sample, I do call transport.shutdown() at the end
of the bean method. Is there some way I can explicitly close the
connection (if that is indeed the problem)? My bean method code and error
stack is at the bottom. Any help would be appreciated.
Regards,
Len Takeuchi
