Re: [Axis2] OMElement question
I have the same as Michele.
From my understanding, if I use signature ReplyObject fooMethod(RequestObject arg) then in the services.xml, I need to specify the message receiver as org.apache.axis2.rpc.receivers.RPCMessageReceiver
, and in the service implementation class, ReplyObject will be the generated classes from WSDL complexType ReplyObject.
If I use the signature OMElement fooMethod(OMElement arg), then I specify the message receiver in services.xml as org.apache.axis2.receivers.RawXMLINOutMessageReceiver.
Can any Axis2 guys tell me what else I need to do? Is there any other databinding issue inside?
Michele, we can also use write our own message receiver to control the data binding.

Xinjun
