Map type and .NET interoperability

[Cun Yong Tan]

Hello,

I have an Axis service that have a single method that returns a Map:

public class ss
{
  public Map echoMap()
  {
    HashMap mapOut = new HashMap();
    mapOut.put("key", "value");
    return mapOut;
  }
}

.NET's wsdl.exe tool is not able to generate a client proxy from
the WSDL for this service. The WSDL (show below) was generated by
   http://localhost:8080/axis/services/ss?wsdl.

Has anyone else have interoperability problems with using Java Map as
parameter and/or return value ?  Is the Map type an Axis only thing ?

Thanks for any help or workarounds.
