Hi, everybody! I have an issue with Java and a web service developed using .NET (C#) (provided by a third-party vendor).
I tried to use axis for creating stub classes and using a Java client to access this web service. So having Eclipse 3.3 and JDK 1.6, I downloaded Axis 1.4 first and later Axis2 1.3, and I got all the code necessary for this Java client to communicate to the web service (using wsdl2java tool). But in all cases the exception I got was the same: A problem with a mustUnderstand header. The thing is the SOAP message for the request doesn't even have a header, as I could see with a handler class I wrote to process the messages.
To add details, I will show you the exception trace:
Exception in thread "main" AxisFault
faultCode: {http://www.w3.org/2003/05/soap-envelope}MustUnderstand

faultString: Did not understand "MustUnderstand" header(s):{http://www.w3.org/2005/08/addressing}Action

The SOAP messages for the request and the response:
Request
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

</s:Reason>
<s:Detail>
<a:ProblemHeaderQName>a:Action</a:ProblemHeaderQName>
</s:Detail>
</s:Fault>
</s:Body>
</s:Envelope>
The thing is that I'm somewhat newbie with using Web Services with Java. As I can see, this response must indicate a problem for the web service understanding the request, so the mustUnderstand header stuff, must refer to the request, but the request message has no header! Am I right? Also, almost all the code is generated, the only code I wrote is for calling the methods and the handler class, which only takes the message and prints it in the standard output.
I hope I have explained this clear enough for you to get the point. How could I solve it? Thanks in advance for your help!
