I'm not even sure you can do that with JAXB, that is, have a Generic as a @XmlRootElement that has an attribute that returns an arbitrary JAXB annotated object. I would try implementing what you're doing with manual JAXB to see if it actually works. The eating of the error is a problem though. (I thought I had cleaned that all up :( ) BTW: Here's the test case for GenericEntity: http://resteasy.svn.sourceforge.net/viewvc/resteasy/tags/RESTEASY_JAXRS_1_0_BETA_8/resteasy-jaxrs/src/test/java/org/jboss/resteasy/test/finegrain/resource/GenericEntityTest.java?revision=347&view=markup Bill Mike Chack (mchack) wrote: > Thanks for the response.
