Description

I'm seeing some client-side serialisation errors when I try to access
my Axis 1.2 rpc/encoded service using a VB .NET client. This same
combination worked in Axis 1.1, but fails with Axis 1.2. I have used
the Axis 1.2 beta from June 14th as well as July 15th separately.

Below is a complete trace of what I did and what the error is.
I've shown

• the signature of the Java service
• the java2wsdl Ant task used to generate the WSDL
• the wsdl2java Ant task used to generate deploy.wsdd
• the VB .NET client
• the SOAP request generated by the .NET client
• the SOAP response when the service was deployed under Axis 1.1
• the SOAP response when the service was deployed under Axis 1.2
  The items shown as ellipses have been elided because they're simply
  values irrelevant to the operation.

The only difference between the two scenarios (1.1 vs. 1.2) is that
I changed the Axis libraries (axis*.jar, commons*.jar, saaj.jar,
wsdl4j.jar, jaxrpc.jar) and re-ran the procedure right from compiling
the service and running java2wsdl and so on.

What has changed between Axis 1.1 and 1.2 in this respect?
