[jira] Created: (CXF-2626) xmlbean databinding nullpointer
xmlbean databinding nullpointer
-------------------------------
Key: CXF-2626
URL: https://issues.apache.org/jira/browse/CXF-2626
Project: CXF
Issue Type: Bug
Components: OtherDatabindings
Affects Versions: 2.2.5
Reporter: Daniel Berg
Priority: Minor
I ran into this little code in the xmlbeans data binding, that always seems to end up in a NullpointerException.
I have a simple webservice(as simple as they get) using previously generated xmlbean from a schema.
The write method gets called with my xmlbean and a valid writer, calls write with MessagePartInfo as null , and a nullpointer exception occurs.
{code:title=org.apache.cxf.xmlbeans.DataWriterImpl.java}
public void write(Object obj, XMLStreamWriter output) {
write(obj, null, output);
}
public void write(Object obj, MessagePartInfo part, XMLStreamWriter output) {
try {
Class<?> typeClass = part.getTypeClass();
.. snip
{code}
{code:title=stack}
DataWriterImpl.write(Object, Object) line: 56

----------------------------------
Using org.apache.cxf.jaxrs.provider.XMLBeansElementProvider as a jaxrs:provider works like a charm, thanks :)
I'll try to make a test case/simpler service reproducing the bug above, but that will not be for a week or two.

---------------------------------------
Can you please try to register
org.apache.cxf.jaxrs.provider.XMLBeansElementProvider as a jaxrs:provider, instead of using jaxrs:dataBinding ?
and I will look into this issue... If you could post a sample service I can test then it can help...
cheers, Sergey

Hi Daniel : can you please post a very simple example which will help me to reproduce the issue. I just need a JAXRS resource with a single method which returns/accepts an XMLBeans bean (simplified as needed)
thanks, Sergey

Excellent, thanks for confirming it. Please test XMLBeansElementProvider, it was contributed awhile back, we can add some more properties to it if needed. Example, the schema you register above will be ignored by XMLBeansElementProvider, so may be we can update it to do the XMLBeans schema validation. Can XMLBeans validate the data ? If you know how then I can update the provider.
> I'll try to make a test case/simpler service reproducing the bug above, but that will not be for a week or two.
ok, no probs, given that XMLBeansElementProvider works, it is not that critical then...
cheers, Sergey

---------------------------------------
I tried to quickly check what might be happening here but I have to admit that without a simplified test case I won't be able to fix it before 2.2.6 gets released.
Can you please simply post :
Service class with a single method only, the response type of this method is an important detail I need to know to do a basic test. If this response type has been generated from a schema then please also attach a sample schema (with the actual schema types/namespaces changed if needed)
thanks, Sergey
