以GenericServlet创建Servlet

1、在FirstServlet同目录下建立GServlet.java

package com.hunhun;import javax.servlet.*;import javax.servlet.http.*;import java.io.*;import java.util.*;public class GServlet extends GenericServlet{   public void service(ServletRequest req,             ServletResponse res)             throws ServletException,                    IOException{            res.getWriter().println("GenericServlet "+new Date().toLocaleString());          }}

2、web.xml

<?xml version="1.0" encoding="ISO-8859-1"?><web-app xmlns="http://java.sun.com/xml/ns/javaee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"  version="3.0"  metadata-complete="true">    <servlet>        <servlet-name>FirstServlet</servlet-name>        <servlet-class>com.hunhun.FirstServlet</servlet-class>    </servlet>    <servlet-mapping>        <servlet-name>FirstServlet</servlet-name>        <url-pattern>/FirstServlet</url-pattern>    </servlet-mapping>    <servlet>        <servlet-name>GServlet</servlet-name>        <servlet-class>com.hunhun.GServlet</servlet-class>    </servlet>    <servlet-mapping>        <servlet-name>GServlet</servlet-name>        <url-pattern>/GServlet</url-pattern>    </servlet-mapping></web-app>

3、编译文件，reload myweb项目，注意每次重新修改*Servlet.java文件,都需要重新编译，并重新加载 myweb项目或重启tomcat7

4、浏览器访问 http://localhost:8080/myweb/GServlet，可看到
