error in WSIF or WS? or both?

Hi,

 

I'm getting a NullPointerException during an exceptional condition when
I try to invoke an Axis service.

 

The error points to the line marked below with >>>>, in
WSIFOperation_ApacheAxis.java:

 

                Map faults = portTypeOperation.getFaults();

                Iterator iter = faults.values().iterator();

                while(iter.hasNext())

                {

                    javax.wsdl.Fault opFault =
(javax.wsdl.Fault)iter.next();

                    // Assuming that there is only one part, fetch it.

                    javax.wsdl.Message wsdlFaultMsg =
opFault.getMessage();

                    Map parts = wsdlFaultMsg.getParts();

                    Part wsdlFaultPart =
(Part)parts.values().iterator().next();

>>>>            if( wsdlFaultPart.getElementName().equals(faultQName) )


                    {

                        faultMsg.setName(
wsdlFaultMsg.getQName().getLocalPart() );

                        faultMsg.setObjectPart( wsdlFaultPart.getName(),
faultElement );

                        faultMsg.setMessageDefinition(wsdlFaultMsg);

                        break;

                    }

                }

 

The problem seems to be that the returned element name is null.

 

In the debugger, the parts field of the message is a HashMap with a null
entrySet. So I'm wondering if the iterator should be checked before
doing anything?

 

The fault in question is decribed as follows:

 

<complexType name="PMServiceException">

  <sequence>

  <element name="errorID" nillable="true" type="soapenc:string" /> 

  <element name="message" nillable="true" type="soapenc:string" /> 

  </sequence>

</complexType>

...

<wsdl:message name="PMServiceException">

  <wsdl:part name="fault" type="tns1:PMServiceException" /> 

</wsdl:message>

 

Did nillable throw something off here in WSIF, the WS or both? 

 

Any ideas on what could be wrong and how to fix it?

 

Thank you for your help!
