Description

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.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!
