Subject: Null Pointer Exception on call.invoke(new Object[]{"test"})

Hi
I'm using Tomcat 5.5, Axis 1.4 and JDK 1.5.0_08.
I have used the Axis WSDL2Java to generate stubs for my service and produced a client that uses these.  The service produces a correct WSDL when i browse to http://localhost:8080/axis/services/Adder?wsdl.
The client however, produces a Null Pointer Error and a debug has shown this to be happening within the Axis code on the Call invoke.
The stack trace is as below.
Does anyone have any suggestions?
Thanks
Caroline
