JAXBElementProvider not able to deal with specific type of classes?
Hello,
(CXF v2.6.1)
We have, say, a JAX-RS interface like this one:
---
@Path("/foo")
public interface Foo {
@Path("/bar")
@POST
@Consumes(MediaType.TEXT_XML)
@Produces(MediaType.TEXT_XML)
JAXBElement<BarTypeTO> doSomething(FooTO);
}
---
FooTO is a class of the following structure (generated by JAXB-Maven-Plugin):
---
public class FooTO extends JAXBElement<ExampleTypeTO> {
protected final static Qname NAME = new Qname("namespace", "foo");
public FooTO(ExampleTypeTO value) {
super(NAME, ((Class) ExampleTypeTO.class), null, value);
}
public FooTO() {
super(NAME, ((Class) ExampleTypeTO.class), null, null);
}
}
---
ExampleTypeTO represents a schema complexType. Schema:
---
<xs:element name="foo" type="exampleType"/>
<xs:complexType name"exampleType">...</xs:complexType>
---
Now, when performing a request to the endpoint from above, I get the following exception:
JAXBException: FooTO is not known to this context.
I debugged JAXBElementProvider and the JAXBContext instance knows all classes from the package of FooTO except FooTO itself and of course the ObjectFactory, which may be correct but why is JAXB not able to unmarshal FooTO? This was working once.
Is there something wrong at line 173-175 in JAXBElementProvider?
Best regards,
Marko

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
