To all:
I am stressing about this exception I am getting. We have a web
service, deployed on JBoss 4.2.5 using Axis 1.4. We were using the
default style, but recently we gained a requirement to support .NET as a
consumer of this WS. The people writing the .NET code reported back to
me that they could not use their auto-generation tools to generate their
code from our WSDL. Through some digging, I uncovered that .NET does
not support RDP:SOAP style, and only supports Document:Literal. So, I
changed the style to "document" and everything seemed fine.
Now, the users of the service are saying they are getting errors when
they actually call the web service. I had written some test client code
that used stubs generated from WSDL2Java, and hadn't updated since
changing to Document:Literal style, so I decided to get it to work
again. Low and behold, if I call one of the no-argument methods, the
call works fine, but as soon as I call any of the methods that have >1
argument, the code explodes with the following:
