怪怪怪，Servlet能用， Jsp却不能用

[xxx353xxx]

各位高人：（WINDOWS2000系统）
　我自从安装Tomcat3.2＋Jdk1.3后，在IE中输入http://localhost:8080后Servlet程序可以运行，但 JSP程序总是显示如下错误：
Error: 500
Location: /examples/jsp/cal/cal1.jsp
Internal Servlet Error:

我在环境设置中进行了如下设置：
CLASSPATH=C:\jdk1.3\lib\tools.jar;c:\jdk1.3\lib\dt.jar
PATH=c:\jdk1.3\bin
JAVA_HOME=c:\jdk1.3
TOMCAT_HOME=c:\tomcat3.2
并将tomcat3.2\lib\下的所有".jar"复制到 c:\jdk1.3\lib\jre中

jdk大家都用4了，很多方法不支持，tomcat5都出好久了，但感觉4还是很好用，3不敢恭维，你应该升级环境，可以从我的ftp下所有的工具，包括linux和windows的

呵呵,你的和我的正相反啊

[windgoogle]

CLASSPATH=.;C:\jdk1.3\lib\tools.jar;c:\jdk1.3\lib\dt.jar

[以梦为马]

既然servlet能用，就说明你环境没问题，问题可能出在你JSP文件是否放对了位置，或者说你在浏览器中输入的地址是否正确。

CLASSPAHT=.;%JAVA_HOME%\lib

不用说明是哪个jar吧?
