我的eclipse版本是3.0.1，tomcat版本是5.30 当
在地址栏中输入http://localhost:8888/Tomcat_test/Hello.jsp就运行正常，
但是如果输入 http://localhost:8888/Tomcat_test/formjsp1.jsp则出现如下出错信息

type Exception report

我的Hello.jsp和formjsp1.jsp位于相同的路径下
谁能帮帮我啊。

Posted by: lele Posted on: 2004-12-27 10:03 前几天碰到同样的报错,将tools.jar复制到tomcat的lib目录中也不行发现原因是用的jdk5.0,安装tomcat自动指向的jvm是jre5.0目录,重新安装,改为jdk5.0目录后运行正常
