OK ... I have not enough information to debug this ...

• do you have a writer associated with this media type? ... XML by default has no associated writer
• do you have a Response implementation associated ?
• can the User object be deserialized ... ?

For instance ... create a XmlWriter ...

public class MyXmlWriter implements HttpResponseWriter<User> {

	@Override
	public void write(User result, HttpServerRequest request, HttpServerResponse response) {

		response.end("<u name=\"" + result.name  + "\" />");
	}
}

Associate the writer with your mime type ... method
RestRouter.getWriters().register(MediaType.APPLICATION_XML_TYPE, MyXmlWriter.class);

or
RestRouter.getWriters().register(User.class, MyXmlWriter.class);

or

@GET
@Path("/h1")
@Produces({MediaType.APPLICATION_XML})
@ResponseWriter(MyXmlWriter.class)
public Response h1() {
	User u = new User("test");
	return Response.ok(u).build();
}
