Android resteasy-mobile示例客戶端

Question

我是Android編程新手，需要實現Android resteasy-mobile客戶端。我需要連接遠程JAX-RS Web服務。我搜索了一下，我找不到一個簡單的示例客戶端。 你能告訴我如何製作Android resteasy-mobile客戶端嗎？

預先感謝您。

最後，我決定實現一個安卓json（傑克遜）客戶端與澤西服務器。 這裏是我的代碼，如果有人需要知道是怎麼回事：

SERVER：

package com.sl; 

import javax.ws.rs.Consumes; 
import javax.ws.rs.GET; 
import javax.ws.rs.POST; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 

import com.sl.model.pojo.UserLocation; 

@Path("/json/service") 
public class JSONService { 

    @GET 
    @Path("/get") 
    @Produces(MediaType.APPLICATION_JSON) 
    public UserLocation getTrackInJSON() { 

     UserLocation ul = new UserLocation(); 
     ul.setCodigo("1"); 
     ul.setLatitud(Float.valueOf("1.1")); 
     ul.setLongitud(Float.valueOf("1.2")); 

     return ul; 

    } 

    @POST 
    @Path("/post") 
    @Consumes(MediaType.APPLICATION_JSON) 
    public Response createTrackInJSON(UserLocation userLocation) { 

     String result = "Record saved."; 
     return Response.status(201).entity(result).build(); 

    } 

} 

的web.xml
