用java servlets 写两个网页 第一页要求输入姓名和电话 有一个save的button 按了botton后 第二页显示 你好

我用纯servlets写了一下，你可以看看：
第一个servlet,Index.java:

package test;

import java.io.IOException;
import java.io.PrintWriter;

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

public class Index extends HttpServlet {

public Index() {
super();
}
public void destroy() {
super.destroy();
}

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=gbk");
PrintWriter pw = response.getWriter();
pw.println("");
pw.println("");
pw.println("

");
pw.println("请输入您的姓名
");
pw.println("请输入您电话号码
");
pw.println("");
pw.println("

");
pw.println("");
pw.println("");

}

public void init() throws ServletException {
}

}
第二个Success.java：

package test;

import java.io.IOException;
import java.io.PrintWriter;

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

public class Success extends HttpServlet {

public Success() {
super();
}

public void destroy() {
super.destroy();
}

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("GBK");
String name = request.getParameter("name");
String phone = request.getParameter("phone");
response.setContentType("text/html;charset=gbk");
PrintWriter pw = response.getWriter();
pw.println("");
pw.println("");
pw.println("欢迎您"+name+"
");
pw.println("您的电话号码是"+phone+"
");
pw.println("");
pw.println("");
}

public void init() throws ServletException {

}

}
web.xml中的配置如下:


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_2_5.xsd">

This is the description of my J2EE component
This is the display name of my J2EE component
Index
test.Index

---希望对你有帮助。

final long serialVersionUID = 1L;
Image imgs[]=new Image[5];
repaint();
改后代码如下：
import java.awt.*;
import java.awt.event.*;
import java.applet.Applet;
public class PlayAudio extends Applet implements ActionListener {
private static final long serialVersionUID = 1L;
Image imgs[]=new Image[5];
Button b2;
public void init() {
setLayout(new FlowLayout()); // 使用布局管理器
imgs[0]=getImage(getCodeBase(),"1.jpg");
imgs[1]=getImage(getCodeBase(),"2.jpg");
imgs[2]=getImage(getCodeBase(),"3.jpg");
imgs[3]=getImage(getCodeBase(),"4.jpg");
imgs[4]=getImage(getCodeBase(),"5.jpg");
b2=new Button("下一张"); // 定义Play按钮
b2.addActionListener(this); // 给Play按钮添加一个监听事件
add(b2);
}
private static int count = 0;
public void actionPerformed(ActionEvent e)
{
//if(e.getSource() == b2)
//{
count=++count%5;
repaint();
//}
}
public void paint(Graphics g)
{

g.drawImage(imgs[count],0,40,this);
}
}
==============================
g.drawImage("m"+count,0,40,this);
这个地方需要传进image类型的对象:m"+count是字符串类型
