代码应该没问题,换了两个tomcat服务器,jsp文件就是说不能编译.下面是访问最简单的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 'MyJsp.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">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
This is my JSP page. <br>
</body>
</html>

答案：An error occurred at line: 23 in the generated java file
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
==》编译错误在这里。
你是不是向工程的lib中添加了很多包，可能是工程中包版本要比tomcat6中的低，造成上面的异常。建议工程中如catalina.jar、jsp-api.jar、servlet-api.jar,javax.servlet.jar 、javax.servlet.jsp等这样包，把它们从工程中删了就应该行了。不是什么包都可以一股脑往工程里加。
其他：不懂，没遇到这个问题。你如果解决了告诉我下什么问题
上一个：哪位帮我看看用JSP写的代码是哪出错了
下一个：谁有猜数字小游戏的JSP代码啊
