jsp+servlet的问题
我用的是eclipse3.0.1+tomcat5+lomboz3.0,我写了一个index.jsp和一个servlet：
我在jsp中使submit提交到servlet上去，可是我的页面刚打开就打不开。
不知道是不是配置有问题，代码如下：
jsp如下：

<body background="#FFFFF">
<form name="form" method="get" action="http://localhost:8080/servlet/FormGetExample1">
<table width="261" height="30">

<p align="center">
<input type="submit" name="submit" value="确定">
<input type="submit" name="submit" value="重来">

servlet如下：

import javax.servlet.*;
import javax.servlet.http.*;
public class FormGetExample1 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out .println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
out.println("<HTML>");
out.println(" <HEAD><TITLE>Servlet Get Example</TITLE></HEAD>");
out.println(" <BODY>");
out.print("<p> </p>");
out.print("<p><font size='+4'>"+"Servlet Get Example"+"</font></p>");
Enumeration Enumeration = request.getParameterNames();
while(Enumeration.hasMoreElements())
{
String key = (String)Enumeration.nextElement();
String value = request.getParameter(key);
out.print("<P>");
out.print(key+"="+value);
out.print("</P>");
}
out.println(" </BODY>");
out.println("</HTML>");
out.flush();
out.close();
}
}
