（2）使用myeclipse创建servlet步骤：继承HttpServlet开发servlet
myeclipse支持jsp/servlet/structs/hibernate/spring…..
步骤：
①使用IDE建立web工程：web server project
②在src中创建包
③在包中new —servlet 一般把URL改为类名
④配置Tomcat 注意要选enable
⑤发布（复制文件） 选择Project 然后选择服务器server
⑥启动Tomcat
需求：post方式提交，并将提交的信息在网页中显示
package com.jdj;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class myhttpServlet extends HttpServlet
{
//回忆<form action="提交给谁" method="post|get"/>默认是get
protected void doGet(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException,
java.io.IOException{
resp.getWriter().println("i am httpservlet doGet()");
}
protected void doPost(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException,
java.io.IOException{
resp.getWriter().println("i am httpservlet doPost()"+req.getParameter("username"));
}
}在WEB-INF平级目录中写login
<html>
<body>
<form action="/jdjweb/myhttpServlet" method="post">
用户名：<input type="text" name="username"/>
<input type="submit" value="登陆"/>
</body>
</html>
