Zarar Siddiqi updated CXF-896:
------------------------------
Attachment: AegisWebFaultFixWithoutChangingWebFaultOutInterceptor.patch
Dan, I'm a little confused. Are we talking about readers or writers? In your
latest comment you're referring to NodeDataReader and XMLStreamReader when the
problem is with *writing* the exception to the stream.
I don't see how we can use classes like W3CDOMStreamWriter in AegisBinding
because they actually need the Element that's being written which isn't
available in AegisDatabinding. Either way, I've attached another patch which
doesn't change WebFaultOutInterceptor and checks for Node.class in AegisBinding
and then returns an ElementDataWriter (new class) which happens to be awfully
similar to XMLStreamDataWriter.
Thoughts? Corrections?

> I'm getting an UnsupportedOperationException using Aegis binding and JAX-WS
> frontend. Here's my setup starting with the Spring beans:
> <bean id="aegisBean"
> class="org.apache.cxf.aegis.databinding.AegisDatabinding"/>
> <jaxws:endpoint
> id="sportsServiceEndpoint"
> implementor="#sportsService"
> address="/SportsService">

> <list>
> <bean
> class="org.apache.cxf.jaxws.support.JaxWsServiceConfiguration"/>
> <bean

> <bean
> class="org.apache.cxf.service.factory.DefaultServiceConfiguration"/>
> </list>
> </property>

> Here's the exception class:
> @WebFault(name="WebServiceException")
> public class WebServiceException extends RuntimeException {
> // constructors hidden for brevity
> public Object getFaultInfo() { .... }
> }
> Here's the stacktrace:
> java.lang.UnsupportedOperationException

> I can actually see this exception coming. In
> WebFaultOutInterceptor.handleMessage() the line
> DataWriter writer = service.getDataBinding().createWriter(Node.class) ;
> invokes AegisDatabinding.createWriter() where Node.class isn't being looked
> for:
> public <T> DataWriter<T> createWriter(Class<T> cls) {
> if (cls.equals(XMLStreamWriter.class)) {
> return (DataWriter<T>)new XMLStreamDataWriter(this);
> } else {
> throw new UnsupportedOperationException();
> }

> Any ideas how to avoid this exception? I think my configuration is correct
> and this might be a bug.
