都配置好了 但是制作测试JSP页的时候就出现错误
语法绝对没问题 出现如下提示
HTTP Status 500 -

message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.

高手指点！
jdk tomcat 都配置好了
测试成功
我简单的写了条测试下效果 代码如下<% @ page contentType="text/html;charset=gb2312" import="java.util.*"%>
<html>
<head>
<title>jsp test
</head>
<body>
<%out.println("测试页面)<br>";
date now = new date();
out.println(new date())
%></body>
</html>

org.apache.jasper.JasperException: Unable to compile class for JSP
你看到这个异常没有？这个异常一般是jsp文件编写错误，里面可能包含错误的代码。
当然，也有可能是你的jdk没有配置好。认真检查一下你的jdk配置。
还有，建议你装好之后用浏览器打开：http://localhost:8080
如果出现提示成功画面，那说明你一切安装完成，就是原来的JSP文件有问题。
一般要把jsp文件放在ROOT目录下才可以正常运行。
我想是你的jsp文件出现了错误了，，，
