Steve,
what do you mean by hang?, does the service wait forever?, what
happens on the server side, any log?
Maybe it won't fix your problem, but here are a couple of advices:
- the soap action usually starts with "urn:" and it's followed by the
operation name
- in the finally block you change the state of your sender object,
which may be null

All,
I am new to Axis and have been trying to update the NonBlockingDual
client to use Transport Asynchrony for a specific web service. The
example works OK if i do not use a separate listener but as soon as
I set options.setUseSeparateListener(true); and run the example it
simply hangs. I am using the default axis2.xml file supplied with
the userguide samples. I have included the source code at the end
of this e-mail.
Is there anything I am doing that is obviously wrong?
Thanks
Steve
