Question

I am new to web service. i am trying to implement a sample wsdl web service through Axis2 engine.

 Versions: Axis2 - > axis2-1.1.1, Ant - > apache-ant-1.8.2

Please help me.

Answer 1

Did you use wsdl2java to generate Java classes from your WSDL? wsdl2java generates a skeleton service class for you, and it generates a services.xml file which says to use the skeleton class as the service class. The automatically-generated skeleton throws an AxisFault with that message for any web service call that it handles. It appears that Axis2 is using this skeleton class as the service class, instead of your service class.

Normally, you will write a service class which extends the skeleton class (or else implements the skeleton interface). When you package the service, you should alter the services.xml file so that it specifies your class as the service class, instead of the automatically generated skeleton class.
