struts2.0+easyUI实现dataGrid，纠结~！
先跟大家说一下我遇到的问题：我用的SSH框架，用的注解，就是想把获取到的list转换成easyUI的Json，然后发送到jsp页面，生成列表，目前我能把list转换成Json对象，而且格式符合easyUI的格式规范，就是不能把Json放到jsp的列表中去。运行jsp页面的时候只能显示一个列表框，没有任何信息！
下面是我的代码：
Action 类：
/**
* 获取角色列表
*
* @author chenj 2010-9-14
*/
@Action(value = "select", results = { @Result(name = "error", location = "/role/saveError.jsp", type = "redirect"),
@Result(name = "success", location = "/role/saveSuccess.jsp", type = "redirect") })
public String getAllUmRole() {
String result = "";
String Json = "";
HttpServletResponse response = ServletActionContext.getResponse();
try {
JSONArray a = new JSONArray();
PrintWriter out = response.getWriter();
List<UmRole> list = entityManager.getAll(UmRole.class);
for (UmRole obj : list) {
a.add(ModelHelper.getInstance().toJSON(obj, true));
}
Json = a.toJSON(false);
out.print(Json.toString());
System.out.println(Json.toString());
result = com.opensymphony.xwork2.Action.SUCCESS;
} catch (Exception e) {
e.printStackTrace();
result = com.opensymphony.xwork2.Action.ERROR;
}
return result;
}
备注：有些类跟方法是自己封装的
JSP页面代码：

运行页面后控制台打印出来的Json：
[{name:"13",des:"13",id:"402880d12b0f715d012b0f71b9d50001"},{name:"123",des:"123",id:"402880d12b0f75ad012b0f75df2c0001"},{name:"345",des:"345",id:"402880d12b0f75ad012b0f77ada30002"},{name:"123",des:"123",id:"402880d12b1db77a012b1db86d9d0001"}]
请教各位高手，如何才能把Json输出到JSP页面并显示出来
