json有关xml问题

                        TestBean msg = new TestBean();

msg.setId("dist1");

msg.setName("peng1");

TestBean msg1 = webResource.accept(MediaType.APPLICATION_JSON_TYPE)
.post(new GenericType <TestBean>() {}, msg);

System.out.println(msg1.getId());

System.out.println(msg1.getName());
我用json客户端接受服务端传过来的对象时。结果是有了，但出现了下面的异常。不知道如何解决。
