10          JSONObject jsonObject = JSONObject.fromObject(jsonString);  
11          Object pojo = JSONObject.toBean(jsonObject, pojoCalss);  
12          return pojo;  
13      }

15      public static String getJsonStringFromObject(Object javaObj) {  
16          JSONObject json = JSONObject.fromObject(javaObj);  
17          return json.toString();  
18      }
