[Resteasy-developers] Issue with Resteasy JAX-RS and interfaces

[Andreas H. <a...@ho...>]

Hello,

I have recently started testing Resteasy JAX-RS. I'm extremely happy so far,
but I have run into a few problems. I have a application that was working
with Jersey that is now deployed on Resteasy. The problem here is the
following:

I have a method in my root resource that returns an interface called Device
such as:

@Path("{id}")
Device getDevice(@PathParam("id") String id);

The device interface in turn has JAX-RS annotations on it:

interface Device {
       @GET
       Device getSelf();
}

The device implementation have several implementations that each one have
different JAX-RS resource. My problem is that it seems to be impossible reach
those resources as it seems that Resteasy always works against the interface
for lookups.

Is this the intended behavior? I don't remember what the JSR says about this,
but it worked fine with Jersey.

Also on a related note it seems that MessageBodyWriter.isWriteable(Class,
Type, Annotation[]) gets passed the declared type of the method instead of
the actual class of the return value. This caused problems with JAXBProvider
as my concrete implementations had a @XmlRootElement annotation but the
actual Device implementation did not.

Oh, both of these issues are tested against 1.0-beta-2, as I don't have time
right now to check against the trunk.
