想在Tomcat里运行JSP文件，就从没成功过，很是郁闷

我照的书的例子写了个有关session对象的JSP文件
放到Tomcat的Webapps文件夹下，
在IE里敲入：http://localhost:8080/page1.jsp
就出现了以下的错误：
=====================================================================================
type Exception report

message  

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Google了一下
把JDK里的Tool.jar文件复制到了Tomcat下，问题还是有
重新看了一下环境变量的设置，classpath没错，设置了tool.jar

请问高手问题出在哪？

在一个地方看到说jdk1.5.0和Tomcat5.0不兼容，有这回事吗？
