Hi,
I'm trying to call a .Net WCF Service from an Axis2 java client on Windows.
Simple calls to the service are working, but I have problems with
a stream returned by one of the methods (see "Exception" below).
The client stub was created with Axis' wsdl2java tool.
I hope somebody can tell me what the problem is and how to fix it...
TIA
Andreas
