the problem of In-only method with throw exception
--------------------------------------------------

                 Key: AXIS2-4408
                 URL: https://issues.apache.org/jira/browse/AXIS2-4408
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: wsdl
    Affects Versions: 1.4.1
         Environment: jdk1.4
            Reporter: qilin
            Priority: Blocker


1.The Service Code:
public class PrintService {

	public void print(String aMessage) throws Exception{
		System.out.println(aMessage);
	}
}

2.The Service.xml:
<service name="PrintService" scope ="application" >
	<Description>
		Please Type your service description here
	</Description>
	<messageReceivers>
		<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"
/>
		<messageReceiver  mep="http://www.w3.org/2004/08/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
	</messageReceivers>
	
	<parameter name="ServiceClass" locked="false">soap.test.PrintService</parameter>
	
	 <!-- 
	<operation name="print">
        <messageReceiver 
		class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>
    </operation>
   
    -->
</service>

3. generate clent code by wsdl2java and run test
    I get the exception
   java.lang.UnsupportedOperationException: An access occurred that is not valid.

4. remove the service.xml comment,the  'An access occurred that is not valid.' not Occurred

5. get the new wdsl from web site,then generate clent code by wsdl2java and run same test
    I get Exception
    The input stream for an incoming message is null.
org.apache.axis2.AxisFault: The input stream for an incoming message is null.
	at org.apache.axis2.transport.TransportUtils.createSOAPMessage(TransportUtils.java:72)
	at org.apache.axis2.description.OutInAxisOperationClient.handleResponse(OutInAxisOperation.java:353)
	at org.apache.axis2.description.OutInAxisOperationClient.send(OutInAxisOperation.java:416)
	at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:228)
	at org.apache.axis2.client.OperationClient.execute(OperationClient.java:163)

  if I do not re generate clent code ,the exception will not Occurred.

 Finally , I fount that wsdl  is different when I remove the comment, 

<wsdl:input message="ns:printRequest" wsaw:Action="urn:print"/>
<wsdl:fault message="ns:Exception" name="Exception" wsaw:Action="urn:printException"/>
--->
<wsdl:input message="ns:printRequest" wsaw:Action="urn:print"/>
<wsdl:output message="ns:printResponse" wsaw:Action="urn:printResponse"/>
<wsdl:fault message="ns:Exception" name="Exception" wsaw:Action="urn:printException"/>

Then generate client code is changed :
__operation = new org.apache.axis2.description.RobustOutOnlyAxisOperation();    //right!
--->
__operation = new org.apache.axis2.description.OutInAxisOperation();                     //error!

By the way, if 
public void print(String aMessage) throws Exception ---> public void print(String aMessage)

will have no problem!
