I am trying to learn WebServices (Axis2)
I am using Jboss EAP 7.0, eclipse_mars with JDK 8, and the latest Axis2 (axis2-1.7.4).
When running the client code,
package com.durgasoft.service;
public class Test {
public static void main(String[] args) throws Exception{
CalServiceStub stub = new CalServiceStub();
//Code to invoke add()
CalServiceStub.Add params =
new CalServiceStub.Add();
params.setI(13);
params.setJ(10);
CalServiceStub.AddResponse
res = stub.add(params);
int result = res.get_return();
System.out.println(result);
}
}
The error that I get is:
Exception in thread "main" org.apache.axis2.AxisFault: The ServiceClass object does not implement the required method in the following form: OMElement add(OMElement e)

I have looked into the below posts on StackOverFlow:
-
tried updating http://www.w3.org/2004/08/wsdl/in-only to http://www.w3.org/ns/wsdl/in-only and http://www.w3.org/2004/08/wsdl/in-out to http://www.w3.org/ns/wsdl/in-out
Tried adding operation tag in the service.xml as described in the Simple axis2.xml for Axis2 embedded in webapp
Also I have even ensured that the messageReceivers described in Axis2.xml and the one mentioned in service.xml are the same. I have completely run out of idea. Kindly help me if you know how to resolve this issue.
I have created the services,
package com.durgaSoft.service;
public class CalService {
public int add(int i, int j){
return i+j;
}
}
I have used eclipse wsdl generation tool to generate WSDL. and the generated WSDL file is as shown below.
This XML file does not appear to have any style information associated with it. The document tree is shown below.
