Please help me to solve this problem.
I might be mistaken, but the
DispatcherServletmapping is pointing elsewhere – it is in fact mapped to *.html, while you are requesting hello.jsp – this skips the dispatcher servlet and goes straight to the JSP page. In addition, your JstlView is configured to fetch JSPs from the WEB-INF folder.Try moving
hello.jspin theWEB-INFfolder and then invoking/hello.htmlinstead.
