Spring MVC - HTTP-статус 500

Question

Я новичок в Spring MVC. (Я знаю Struts MVC, но мне нужно изучить Spring MVC.) Я пытаюсь получить первую страницу своего приложения (находящегося в /WEB-INF/jsp/Welcome.jsp), но я получаю следующее сообщение :

HTTP Status 500 - 

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

type Exception report 

message 

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

exception

Answer 1

Я считаю, что я решил проблему. Я работаю под Tomcat 7, но я думаю, что у меня были кувшины для Tomcat 6. Я заменил их в папке lib, и это сообщение об ошибке исчезло.
