Kohsuke ,
Thanks for your advice.
I get msv.20040219.zip and replaces all the jars there in my classpath (6 of them in total), but it does not work. I still have the NullPointer exception.
And I get my SOAP message like this:
SOAPMessage response = con.call(request, endpoint); // con is SOAP connection in SAAJ implemention comes with JWSDP 1.3
And pass one of the SOAP Body Element to the unmarshaller, but I got a Null Pointer exception.
How can I turn on the namespace processing in SAAJ SOAP connection ?
Thanks in advance.
