TOMCAT6.0+JSP本地调试问题：急~~~~
本人是JSP菜鸟没什么基础就会照抄现在遇见这样的问题：
用CUTFTP把所有WEB文件从外网服务器下载到本地的c:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\ROOT的文件夹下
浏览器输入http://localhost:8080/html/index.htm和外网的效果一样
然后在这个文件夹下新建一个TEST.JSP内容为显示HELLO WORLD浏览器输入http://localhost:8080/test.jsp也能正常显示
但是我点击http://localhost:8080/html/index.htm上一个导航链接，链接到http://localhost:8080/html/zhengce/index.jsp就报错了错误内容为以下代码：（在文章最后）
然后我点击另外一个导航链接，链接到http://localhost:8080/html/zhuanjia/index.htm则能够正常显示
后来我发现只要是JSP文件都不能显示且报HTTP500错误，HTM文件都能显示，并且这些导航链接在外网服务器上点没有任何问题，为什么下到本地就不能显示JSP文件了呢？再说我的test.jsp都能显示啊，我承认我是菜鸟而且刚刚自学接触JSP，希望各位达人能解决我的问题，不胜感激！！！！
我的环境是JDK6.0+TOMCAT6.0
HTTP Status 500 -

[解决办法]
zhengce目录下有没有WEB-INF目录？
[解决办法]
zhengce下建个WEB-INF目录，重启Tomcat应该就好了
[解决办法]
顶楼上的,WEB-INF里有没有web.xml
[解决办法]
顶一下了
搞个配置文件 就好了
