Thank you for the hint! Returning a GenericEntity wrapped collection also
works, as you suggested.
@GET
@Path("/jobs.xml")
@Produces(MediaType.APPLICATION_XML)
public Response getJobs() {
GenericEntity<List<JobImpl>> entity = new
GenericEntity<List<JobImpl>>(getJobs()) {};
return Response.ok(entity).build();
}
Thanks,
Josh
