------解决方案--------------------
先要转换成javascript能够识别的数据类型
才能够遍历

------解决方案--------------------
List<BaseUser> list = this.userMng.findUserList(orgId);
JSONArray arr = new JSONArray();
JSONObject o;
for(BaseUser user : list){
	o = new JSONObject();
	o.put("id", user.getId());
	o.put("name", user.getUsername());
	arr.put(o);
}

将arr.toString()通过response返回到页面：
response.setContentType(contentType);
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
try {
	response.getWriter().write(text);
} catch (IOException e) {
	e.printStackTrace();
}

页面遍历json:
$.getJSON("../group/group_loadUser.do?orgId="+orgId, function(json){
	for(var i=0;i<json.length;i++){
              alert("id:" + json[i].id + "  name:" + json[i].name);
       }	
});  




------解决方案--------------------
response.setContentType(contentType);
改为:
response.setContentType("text/xml;charset=UTF-8");

response.getWriter().write(text);
改为：
response.getWriter().write(arr.toString());
