Vilnis Termanis commented on AXIS2-4408:
----------------------------------------

Reproduced with Axis 1.6.1

1) Create POJO service with non-returning function which throws a custom exception, e.g.:
public class ExampleService { public void update(String something) throws Fault {} }
(Fault is very simply, just extends Exception.)

2) Include RPCInOnlyMessageReceiver & RPCMessageReceiver in <messageReceivers> tag.

3) Try to call function from client.

RESULT:

org.apache.axiom.om.OMException: localname can not be null or empty

    at java.lang.Thread.run(Thread.java:662)

Currently the only two ways to make it work are:

1) Make the function return something, e.g.:
public boolean update(String something) throws Fault { }

2) Explicitly define update() as "InOnly" in services.xml:
<operation name="update"><messageReceiver class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" /></operation>

> <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!
