JsonObject map

Question

想试试jsonObject组成JSON数据，可是一直报错，这是为啥呢
[code="java"]
public static void main(String[] args) throws Exception {

Map map = new HashMap();

    map.put("name", "json");

    map.put("bool", "Boolean.TRUE");

    map.put("int", "new Integer(1)");


    map.put("func", "function(i){ return this.arr[i]; }");
    System.out.println(map);
    JSONObject json = JSONObject.fromObject(map);
    System.out.println(json);
}  

[/code]

[code="java"]
{int=new Integer(1), name=json, func=function(i){ return this.arr[i]; }, bool=Boolean.TRUE}

缺少jar包，使用Object不只依赖当前的存有JsonObject对象的包，还有些其他Jar包。
要使程序可以运行必须引入JSON-lib包，JSON-lib包同时依赖于以下的JAR包：
1.commons-lang.jar
2.commons-beanutils.jar
3.commons-collections.jar
4.commons-logging.jar
5.ezmorph.jar
6.json-lib-2.2.2-jdk15.jar
