[jboss-user] [JBossWS] - .NET client failed to invoke web service on JBoss

[csupercowboy]

Hi,

I created a Hello World web service and deployed it on JBoss 4.0.1sp1. This web service only has one method which prints a Hello world message. I created Java clients and they succeeded to consume this service. But when I use a .NET client to try to invoke the method, it always failed. The Java client, .NET client and the JBoss server are on the same machine. The service was created following the JBoss AS documentation Chapter 12. 

When my .NET client tries to invoke the method, I always got a 500 error saying "The server encountered an internal error () that prevented it from fulfilling this request. "

The exception stack starts with
java.lang.NullPointerException
org.apache.axis.encoding.DeserializationContextImpl.getTypeMapping.....
org.apache.axis.encoding.DeserializationContextImpl.getDeserializer.....
.....

Any help would be greatly appreciated. Thanks.

Arthur
