一个奇怪的问题在wsad5.1的servlet不能用req.getParameter???

[zdnetchina]

根据例子
http://www-900.ibm.com/developerWorks/cn/wsdd/education/campaign/wes/wesdynweb5/tutorial/index.html

String username = req.getParameter("username"); 编辑器出错!

不可能，好好查查自己的问题！

代码如下：

package com.ibm.tutorials.wssd;

import java.io.IOException;

import java.util.*;

import javax.servlet.RequestDispatcher;
import javax.servlet.Servlet;
import javax.servlet.ServletException;

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

import org.omg.CORBA.Request;

/**

public class MessageCenterLoginServlet extends HttpServlet implements Servlet {

/**
* @see javax.servlet.http.HttpServlet#void (javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
*/
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {

this.doPost(req, resp);
}

/**
* @see javax.servlet.http.HttpServlet#void (javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
*/
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {

String username = request.getParameter("username");

User user = User.getUser(username);
if (user == null) {
req.setAttribute("errorMessage", "User not found");
RequestDispatcher disp = getServletContext().getRequestDispatcher("/login.jsp");
disp.forward(req, resp);
}

// Put the user object in the session object and forward to messageCenter JSP
HttpSession session = req.getSession(true);
session.setAttribute("user", user);
RequestDispatcher disp = getServletContext().getRequestDispatcher("/messageCenter.jsp");
disp.forward(req, resp);

}

}

超长问题，帮你up

[peercy]

把request 改成req
HttpServletRequest req
我这里还有一个User的类不能识别，那是你那边的问题了

其他没有看见别的问题啊！
