关于struts+hibernate提交数据的问题
有段程序不太明白，每次我把加粗的部分，换成 "request.setAttribute("msg", "<font color=red>"+username+"</font>"+" 注册成功！");"的时候，数据的无法提交了，而且数据返回的页面也是一片空白，返回页面中使用了<bean:write name="msg" />不知道是为什么，请各位指教！！！

action.java:
package com.yourcompany.struts.action;

import java.io.Serializable;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.hibernate.Session;
import org.hibernate.Transaction;


import com.mine.hiber.Login;
import com.mine.hiber.SessionFactory;
import com.yourcompany.struts.form.LoginForm;

public class LoginAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;// TODO Auto-generated method stub
String username=loginForm.getUsername();
String password=loginForm.getSss();
Session session =SessionFactory.getSession();
Login user=new Login(username,password);
session.save(user);
Transaction tx=null;
  tx=session.beginTransaction();

tx.commit();
session.close();
HttpSession sessions = request.getSession();
sessions.setAttribute("msg", "<font color=red>"+username+"</font>"+" 注册成功！");
return mapping.findForward("su");
}
}

------解决方案--------------------
<action
attribute="loginForm"
input="/login.jsp"
name="loginForm"
path="/login"
scope="request"
type="com.yourcompany.struts.action.LoginAction" /> 
红色的改成 scope="session"试试。
