I've set up web.xml as below. I also have an annotation-based controller, which takes in any URL pattern and then goes to the corresponding jsp (I've set that up in the -servlet.xml). However, If I go to a page that ends in .html (and whose jsp doesn't exist), I don't see the custom 404 page (and see the below error in the log). Any page that doesn't end in .html, I can see the custom 404 page.
How can I configure to have a custom 404 page for any page that goes through the DispatcherServlet?
Also want to add that if I set my error page to a static page (ie. error.htm) it works, but if I change it to a jsp (ie. error.jsp), I get the IllegalStateException. Any help would be appreciated.

One option is to map all your error pages through your dispatcher servlet.
Create a new HTTP error controller:
@Controller public class HTTPErrorController { @RequestMapping(value="/errors/404.html") public String handle404() { return "errorPageTemplate"; } @RequestMapping(value="/errors/403.html") ... }
Map the error pages in web.xml
<error-page> <error-code>404</error-code> <location>/errors/404.html</location> </error-page>
