I've tried almost every Spring MVC HTTP error 500 solution out there. But they are not solving the error I'm getting. What is causing the error, and how can I solve it?

回答by Tanvir Hossain Khan
I guess the problem is with the notices-servlet.xmlfile. Check the "WEB-INF" folder for the ServletContext resource. Try again running the project after putting the notices-servlet.xml in the "WEB-INF" folder. Hope that will do!
我猜问题出在notices-servlet.xml文件上。检查 ServletContext 资源的“WEB-INF”文件夹。将 notices-servlet.xml 放入“WEB-INF”文件夹后，再次尝试运行该项目。希望能做到！
