Re: Interoperability Axis with .NET (C#)

When I used Axis 1.0 with .NET I ran into problems with the namespace in the Axis generated WSDL.  There is a bug report on this and that may be fixed in 1.1.

I worked around this by fixing the C# code that was generated and added the proper name space string to the class definitions.

RE: Interoperability Axis with .NET (C#)
Using the Axis1.0 samples for encoding using custom serralizer/deserializer, I wish to pass an array of complex data types to .Net(C# Web Reference).  In addition, I am using Java2Wsdl. 
The C# .Net side Web Refernce auto-generated code catches System.InvalidOperationException: There is an error in XML document (5, 5). ---> System.InvalidOperationException: Namespace prefix 'null' is not defined.
 
Below is the relevant Java code:
 
<!--server-config.wsdd data service entry -->
<service name="ElementService" provider="java:RPC">
        <parameter name="className" value="com.bah.tia.portal.service.elementService.ElementService"/>

      languageSpecificType="java:com.bah.tia.portal.domain.Data"
                     serializer="com.bah.tia.portal.util.customSerialization.DataSerFactory"
