Hi,

I'm having a problem trying to build a client for my service with cxf. My service is up and running, but whenever I try and access it from a client I'm getting null pointer exceptions. The code to setup my client looks like this:

   // SNIP
   JaxWsProxyFactoryBean proxyFactory = new JaxWsProxyFactoryBean();

   proxyFactory.getInInterceptors().add(new LoggingInInterceptor());
   proxyFactory.getOutInterceptors().add(new LoggingOutInterceptor());

   proxyFactory.setServiceClass(FluxionService.class);
   proxyFactory.setAddress(serviceURL);
   proxyFactory.setDataBinding(new AegisDatabinding());

   FluxionService fs = (FluxionService)proxyFactory.create();
   // SNIP

Now, I should be able to do:
Set<URI> uris = fs.getDataSources();

to retrieve a set of URIs from this service. When I make this call, I get the following SOAP request and response:

Request:

 <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
   <soap:Body>
<ns1:getDataSources xmlns:ns1="http://service.fluxion.comparagrid.org/"; />
   </soap:Body>
 </soap:Envelope>

Response:

 <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
   <soap:Body>
<ns1:getDataSourcesResponse xmlns:ns1="http://service.fluxion.comparagrid.org/";>
       <return>
<ns2:anyURI xmlns:ns2="http://impl.service.fluxion.comparagrid.org/";>
           http://metagenome.ncl.ac.uk/cgdemo.owl
         </ns2:anyURI>
       </return>
     </ns1:getDataSourcesResponse>
   </soap:Body>
 </soap:Envelope>

That's exactly what I'd expect. However, the actual Set<URI> returned in my app is null, so I'm seeing NPEs whenever I try and iterate over this set. What's going on here? I'm relatively new to CXF as I've just ported over from XFire so I'm prepared to admit that I might be missing something fundamental but this looks pretty weird to me.

Any advice would be highly appreciated as this is driving me mad!

Thanks,

Tony
