With the web xml configured they way you have in the question  in particular    lt servlet-mapping gt       lt servlet-name gt dispatcherServlet lt  servlet-name gt       lt url-pattern gt    lt  url-pattern gt   lt  servlet-mapping gt    ALL requests being made to your web app will be directed to the DispatcherServlet  This includes requests like  tasklist    tasklist some-thing html   tasklist WEB-INF views index jsp    Because of this  when your controller returns a view that points to a  jsp  instead of allowing your server container to service the request  the DispatcherServlet jumps in and starts looking for a controller that can service this request  it doesn t find any and hence the 404   The simplest way to solve is to have your servlet url mapping as follows    lt servlet-mapping gt       lt servlet-name gt dispatcherServlet lt  servlet-name gt       lt url-pattern gt   lt  url-pattern gt   lt  servlet-mapping gt    Notice the missing    This tells the container that any request that does not have a path info in it  urls without a  xxx at the end   should be sent to the DispatcherServlet  With this configuration  when a xxx jsp request is received  the DispatcherServlet is not consulted  and your servlet container s default servlet will service the request and present the jsp as expected   Hope this helps  I realize your earlier comments state that the problem has been resolved  but the solution CAN NOT be just adding method RequestMethod GET to the RequestMethod

Try passing the Model object in your index method and it will work-    RequestMapping       public String index org springframework ui Model model      return  index            Actually the spring container looks for a Model object in the mapping method  If it finds the same it will pass the returning String as view to the View resolver   Hope this helps
