jsp 里的 getjsonobject 报错

[kelos]

2016-7-22 15:46:12 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet [jsp] in context with path [/IP_check] threw exception [An exception occurred processing JSP page /postjson_do.jsp at line 34

31: System.out.println(getjsons);
32:
33: JSONObject getjson = new JSONObject();
34: JSONObject newObj = getjson.getJSONObject(getjsons);
35:
36: System.out.print(newObj);
37: JSONObject jsa = newObj.getJSONObject("data");


以上代码一直报错， import 用的是：

<%@ page language="java" import="java.util.*" import="org.json.JSONObject" import="java.sql.*" pageEncoding="utf-8"%>

引用到的 json 包有 org.json.jar 和 json-lib-2.2.3-jdk15.jar

求助啊

解决了，直接 new JSONObject(String).
