JSP子目录问题--无法编译jsp
我创建了一个网站并托管在 windows 和 tomcat 6 上。
当我们从子目录访问JSP文件时，应用程序无法检测到WEB-INF->classes文件夹中的类文件。
我创建了一个 jsp 文件来访问类文件。当我从根文件夹访问 JSP 时，它工作正常。如果我将相同的 jsp 文件放入子目录中，则会抛出错误：
HTTP 状态 500 -

中工作，谢谢 亚历克斯
I have created a website and hosted on windows and tomcat 6 .
The application could not detect the class files in WEB-INF->classes folder when we access the JSP file from the subdirectory.
I created a jsp file to just access a class file. The JSP is working fine when I access it from root folder. If i put the same jsp file in the subdirectory, it is throwing errors saying

虽然我不知道为什么它在放置在子目录中时不起作用，但如果它在根目录中工作正常，但在行中，为什么不尝试呢？
Although I don't have answer why it is not working when placed in sub directory, if it was working fine in root directory, but in line , why don't you try .
