Is it working for you now? I just added a system test testGetCDsJSON() in http://svn.apache.org/viewvc/incubator/cxf/trunk/systests/src/test/java/org/apache/cxf/systest/jaxrs/JAXRSClientServerBookTest.java?view=log. In this test, a CDs object is returned to the client side in JSON format. The CDs object contains a list of CD object. It works, not sure if this is similar to what you want to achieve.
