[Axis 2] NullPointerException in RPCMessageReceiver.invokeBusinessLogic

[Emmanuel GUITON <Em...@intrinsec.com>]

Hello all,

I implemented a web-service and I am running into trouble with a custom soap fault message.
Each time I throw the corresponding Java exception, I get the following soap fault :
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring>java.lang.NullPointerException</faultstring>
<detail />
</soapenv:Fault>

Which is not my own exception. In fact, the NullPointerException comes from the invokeBusinessLogic method in org.apache.axis2.rpc.receivers. RPCMessageReceiver
java.lang.NullPointerException
                at org.apache.axis2.rpc.receivers.RPCMessageReceiver.invokeBusinessLogic(RPCMessageReceiver.java:179)
                at org.apache.axis2.receivers.AbstractInOutMessageReceiver.invokeBusinessLogic(AbstractInOutMessageReceiver.java:40)

Indeed, inMessage.getAxisService().getTypeTable() returns NULL in the following code :
177                    String partQName = inMessage.getAxisService().getName() + getSimpleClassName(exceptionType);
178                    TypeTable typeTable = inMessage.getAxisService().getTypeTable();
179                    QName elementQName = typeTable.getQNamefortheType(partQName);

I am stuck with this error. Does anyone has an idea about what I could do wrong ?

I am using jaxws-maven-plugin to generate the bindings, Axis2 1.6.1 webapp in a tomcat 7 server to deploy the generated AAR file.
And here is the definition of my own fault message :

<wsdl:message name="faultResponse">
                <wsdl:part element="lbp:faultResponse" name="content" />
</wsdl:message>

<complexType name="FaultType">
                <sequence>
                               <element minOccurs="0" name="reason" type="string" />
                </sequence>
</complexType>

Thanks for any help,

-          emmanuel
