Hi,
The instance returned by the resource method is the instance that is
marshaled by JAXB, essentially using the following:
http://java.sun.com/javase/6/docs/api/javax/xml/bind/Marshaller.html#marshal(java.lang.Object,%20java.io.OutputStream)
So you could do:
@GET
@Produces( { MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
@Path("/read/{id}")
public Object read(@PathParam("id") String id) {
return userFacade.read(new Long(id));
}
and the same behavior will occur.
Paul.
