Major Description
If we have a wsdl with an operation like this (Where "tns:SimpleMessage" may be just a "xsd:string"):
<wsdl:portType name="SimplePortType">
<wsdl:operation name="SimpleOperation">
<wsdl:input message="tns:SimpleMessage"/>
</wsdl:operation>
</wsdl:portType>
WSDL2Java generates a Message Receiver that extends "AbstractInOutSyncMessageReceiver" instead of "AbstractInMessageReceiver":
public class SimplePortTypeMessageReceiver extends org.apache.axis2.receivers.AbstractInOutSyncMessageReceiver
{ ... }Also, in the Stub, operations are registered as "OutInAxisOperation", instead of "InOnlyAxisOperation":
_operations = new org.apache.axis2.description.OutInAxisOperation[1];
Any attept to use the stub to comunicate with the service will result in the following exception:
org.apache.axis2.AxisFault: org.apache.axis2.AxisFault: Raw Xml provider supports only the methods bearing the signature public OMElement <method-name>(OMElement) where the method name can be anything

If we add an output message to the operation, then everything works perfectly (but the operation isn't oneway any more):
<wsdl:portType name="SimplePortType">
<wsdl:operation name="SimpleOperation">
<wsdl:input message="tns:SimpleMessage"/>
<wsdl:output message="tns:SimpleMessage"/>
</wsdl:operation>
</wsdl:portType>
Trying to manually change Message Receiver generated, so it extends "AbstractInMessageReceiver" results in more exceptions difficult to solve.
