We have an Axis2 JAXWS service which is consumed by JAXWS clients as well as Axis1.x clients(JAXRPC).
The parameter names generated by our web service have arg0 etc. But when the Axis1.x clients use the same WSDL and send a message, we do not get parameters as arg0 but instead we get them as the request object name.
The request message in the service implementation class is fine in case of JAXWS client but it is Null in case of Axis1.x client.
The same web service used to work fine on Websphere 6. But recently we migrated to Websphere 8 and it started failing. We cannot ask clients to modify.
