Using a web service to return HashMap. The Java Axis web services consumer app then works perfectly. However, when I try to register the web service in a .NET C# app, I am getting an error of "Object reference not set to an instance of an object". This actually worked when using a Hashtable in the webservice as the return type but doesn't when using the HashMap. Whereas Axis client had problem with the Hashtable return object.
Any ideas? Chris Peake
