Eric Deshayes commented on AXIS2-1964:
--------------------------------------
forget my last comment, it is partially true.
the problem is not about any inherited type.
it's more about the namespace of referenced schema
when i set a break point in the public final void receive(MessageContext
msgContext) throws AxisFault method of the
org.apache.axis2.receivers.AbstractInOutSyncMessageReceiver class, when the
message context is send back to the engine (engine.send(outMsgContext);), here
is the content of the envelope of that message:
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Header />
<soapenv:Body>
<ReportService_GetOlapServers_1_0_Response xmlns="http://reportservice.type";>
<status>
<returnCode xmlns="">
<returnCode>
0</returnCode>
</returnCode>
</status>
<olapServerId xmlns="http://type.ws.analyzer.jrisk.appl.net";>
jnp://192.168.111.66:1234</olapServerId>
</ReportService_GetOlapServers_1_0_Response>
</soapenv:Body>
</soapenv:Envelope>
I guess the problem comes from the namespace declared in the returnCode element
that is empty.

> We were actually looking for the fix of Bug 1856 in 1.1.1 as our IBM
> Webservice WSDL contains Abstract element, which is causing problems writing
> handlers on our service side on the SOAP Request after deserialization. But
> now the client stopped creating SOAP Request because of above NPE. I am not
> sure whether the Bug 1856 and above problem is related.
