Hello,

I think, I know the problem.

I have written an example like this:

---
FooTO foo = new FooTO();

JAXBContext context = 
JAXBContext.newInstance(foo.getClass().getPackage().getName());
// this context looks like the context from AbstractJAXBProvider:438 (both 
support the same types)
context.createMarshaller().marshal(foo, outputStream);
InputStream in = /* make inputstream from outputstream */

context.createUnmarshaller().unmarshal(in) // works
context.createUnmarshaller().unmarshal(new StreamSource(in), foo.getClass()) // 
fails because FooTO is not known to this context


CXF is using the second unmarshalling behavior.

Any ideas, how to get around this?



Best regards,
Marko

Subject: RE: JAXBElementProvider not able to deal with specific type of classes?

Hello Sergey,

I've updated from CXF 2.5.1 to 2.6.1.

We are using our own JAXBElementProvider, which extends from 
JAXBElementProvider in order to add a xml-stylesheet to the top of the returned 
XML.

I had to change the code from:

MyJAXBElementProvider extends JAXBElementProvider

To:

MyJAXBElementProvider extends JAXBElementProvider<Object>

Otherwise the code could not compile because of the overridden method 
setMarshallerProperties.

Maybe it has something to do with this? I doubt that.

I was performing a manual un-/marshalling of this kind of class and it worked. 
I have no idea what is wrong here. Both JAXBContext instances have the same 
output for toString().


Best regards,

I do not actually remember changing anything that may've affected the 
processing of classes like FooTO which extend JAXBElement.
When did it work last time ? May be it is to do with the JAXB impl versions ?

Thanks, Sergey
