求救：jsp页面错误
麻烦帮忙看看是怎么回事，非常感谢！系统使用tomcat6，部署在linux下，不是用root用户启动tomcat， 访问jsp页面时页面报错，如下：

--------------------编程问答-------------------- Unable to compile class for JSP
编译jsp出错。看一下是不是jdk路径配置错误，还是程序没有权限该问jdk --------------------编程问答-------------------- jdk没错的，jdk如果配置错了，tomcat是没法启动的 --------------------编程问答--------------------
1. 检查发布包里 classes 文件夹下是否存在编译文件。
2. 查看第一个页面的 jsp 表头是否存在特殊的标签符。 --------------------编程问答-------------------- 你在eclipse里面从新把tomcat加载一下 从新试试 --------------------编程问答-------------------- sudo root改下权限试试。
补充：Java , Web 开发
