我在用tomcat运行servlet时提示出现一下错误:

HTTP Status 500 -

--------------------------------------------------------------------------------

type Exception report

message

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

exception

javax.servlet.ServletException: Error allocating a servlet instance

烦请各位帮忙看一下到底是什么原因,我servlet放的位置也是对的,web.xml也配置了,环境变量也设置了,不知道为什么还是会出现这样的问题.希望各位指点一下,再次感谢您看我的帖子,更感谢您的回复!
