Hi Everybody,
I would like to modify the code generated by wsdl2java in order to have
a dual blocking client because the web service operation that I'm
calling is particularly time consuming. I had a look at the
EchoBlockingDualClient.java example and have come up with the following
code. But I get a null pointer exception.
Can someone please tell what I'm doing wrong?
Thanks very much!
Diego
