如何使我的Netbeans Java Rest Client访问Post方法？

我有使用以下几种方法的netbean Rest Web服务项目：

@Path("restws")

公共类RestWs {

@Context
private UriInfo context;

public RestWs() {
}


@GET
@Produces("application/json")
public String getJson() {
    return ("{\"pesan\":\"hello\"}");
}


@PUT
@Produces("text/plain")
@Consumes("application/json")
public String putJson(String content) {
    return("Content yang didapat : "+content);
}

@Path("/mahasiswaData/{id}")
@GET
@Produces("application/json")
public String getMahasiswaByID(@PathParam("id")String nim)
{
    JSONObject jo = new JSONObject();
    jo.put("id", nim);
    jo.put("nama", "Budi");
    return(jo.toJSONString());
}

@Path("/mahasiswaData/{id}")
@POST
@Consumes("text/plain")
@Produces("application/json")
public String postMahasiswaByID(@PathParam("id")String nim, String data)
{
    JSONObject jo = new JSONObject();
    jo.put("id", nim);
    jo.put("nama", "Budi");
    jo.put("message", data);
    return(jo.toJSONString());
}

@Path("/mahasiswaQuery")
@GET
@Produces("application/json")
public String getMahasiswaQuery(@QueryParam("nim")String nim, @QueryParam("nama") String nama)
{
    JSONObject jo = new JSONObject();
    jo.put("nim", nim);
    jo.put("nama", nama);
    jo.put("method", "GET");
    return(jo.toJSONString());
}

@Path("/mahasiswaQuery")
@POST
@Produces("application/json")
public String postMahasiswaQuery(@QueryParam("nim")String nim, @QueryParam("nama") String nama)
{
    JSONObject jo = new JSONObject();
    jo.put("nim", nim);
    jo.put("nama", nama);
    jo.put("method", "Post");
    return(jo.toJSONString());
}

}

然后我做一个新的项目，并添加其余的Web服务客户端。netbeans自动使​​我成为一个新的班级：

public class NewJerseyClient {
private WebTarget webTarget;
private Client client;
private static final String BASE_URI = "http://localhost:8080/PTIRestServer/webresources";

public NewJerseyClient() {
    client = javax.ws.rs.client.ClientBuilder.newClient();
    webTarget = client.target(BASE_URI).path("restws");
}

public String putJson(Object requestEntity) throws ClientErrorException {
    return webTarget.request(javax.ws.rs.core.MediaType.APPLICATION_JSON).put(javax.ws.rs.client.Entity.entity(requestEntity, javax.ws.rs.core.MediaType.APPLICATION_JSON), String.class);
}

public String getMahasiswaByID(String id) throws ClientErrorException {
    WebTarget resource = webTarget;
    resource = resource.path(java.text.MessageFormat.format("mahasiswaData/{0}", new Object[]{id}));
    return resource.request(javax.ws.rs.core.MediaType.APPLICATION_JSON).get(String.class);
}

public String postMahasiswaQuery() throws ClientErrorException {
    return webTarget.path("mahasiswaQuery").request().post(null, String.class);
}

public String getMahasiswaQuery(String nim, String nama) throws ClientErrorException {
    WebTarget resource = webTarget;
    if (nim != null) {
        resource = resource.queryParam("nim", nim);
    }
    if (nama != null) {
        resource = resource.queryParam("nama", nama);
    }
    resource = resource.path("mahasiswaQuery");
    return resource.request(javax.ws.rs.core.MediaType.APPLICATION_JSON).get(String.class);
}

public String postMahasiswaByID(Object requestEntity, String id) throws ClientErrorException {
    return webTarget.path(java.text.MessageFormat.format("mahasiswaData/{0}", new Object[]{id})).request(javax.ws.rs.core.MediaType.TEXT_PLAIN).post(javax.ws.rs.client.Entity.entity(requestEntity, javax.ws.rs.core.MediaType.TEXT_PLAIN), String.class);
}

public String getJson() throws ClientErrorException {
    WebTarget resource = webTarget;
    return resource.request(javax.ws.rs.core.MediaType.APPLICATION_JSON).get(String.class);
}

public void close() {
    client.close();
}

}

我可以通过使用类似以下内容轻松访问所有的get方法：

public static void main(String[] args) {
    System.out.println(new NewJerseyClient().getMahasiswaQuery("23", "John"));
}

但是当我尝试使用此代码访问发布/发布方法时：

 public static void main(String[] args) {
    NewJerseyClient c = new NewJerseyClient();
    System.out.println(c.putJson("{\"name\":\"john\"}"));
    System.out.println(c.postMahasiswaQuery());
    System.out.println(c.postMahasiswaByID("plain text", "1"));
}

所有的方法调用都给我一个例外：

Exception in thread "main" javax.ws.rs.NotAcceptableException: HTTP 406 Not Acceptable
at org.glassfish.jersey.client.JerseyInvocation.convertToException(JerseyInvocation.java:898)
at org.glassfish.jersey.client.JerseyInvocation.translate(JerseyInvocation.java:749)

at client.NewJerseyClient.postMahasiswaByID(NewJerseyClient.java:68)
at client.NewJerseyClient.main(NewJerseyClient.java:84)

谁能帮我？如何访问方法放置/发布？还是有人有示例代码如何访问这些方法？

谢谢
