不说废话 直接代码
jsp的代码
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

<url-pattern>/servlet/connServlet</url-pattern>
你看你的url，如果你的这个jsp文件是在servlet目录下的话，是没有问题的
如果是你的jsp页面是webroot的根路径下的话，你的>
<form name="loginForm" method="post" action="connServlet">
应该改成
><form name="loginForm" method="post" action="servlet/connServlet">
<servlet-class>connServlet</servlet-class> 改为<servlet-class>工程名/connServlet</servlet-class>
