服务端java处理:
ArrayList list = new ArrayList();
SimpleInfo info = new SimpleInfo();
info.setAge("19");
info.setName("Joe");
info.setSex("male");
SimpleInfo info2 = new SimpleInfo();
info2.setAge("18");
info2.setName("youe");
info2.setSex("female");

list.add(info);
list.add(info2);

response.setContentType("text/xml;charset=utf-8");
net.sf.json.JSONArray jsonArray = net.sf.json.JSONArray.fromObject(list);
System.out.println(jsonArray);
response.getWriter().print("{}" + jsonArray);



前台无法读取服务端传回来的数据?请高人指教?

请各位指教!!!.
