This is probably an easy one, but I’m missing something I guess. The problem comes down to this: I am trying to use a HelloController to display “/WEB-INF/hello.jsp”. Unfortunately, I get a 404 when trying to access http://example.com/app/hello

Here is the code. Probably an easy fix.

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

</beans>

HelloController.java:

@Controller
public class HelloController {

    @RequestMapping(value="/hello", method=RequestMethod.GET)
    public ModelAndView helloWorld() {
        ModelAndView mv = new ModelAndView();
        mv.setViewName("hello");
        return mv;
    }
}

hello.jsp:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

   <title>Hello</title>
</head>
<body>
<p>Hello</p>
</body>
</html>

Update: Added error message per request.

Error 404–Not Found From RFC 2068 Hypertext Transfer Protocol —
HTTP/1.1:
10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No
indication is given of whether the condition is temporary or
permanent.

If the server does not wish to make this information available to
the client, the status code 403 (Forbidden) can be used instead. The
410 (Gone) status code SHOULD be used if the server knows, through
some internally configurable mechanism, that an old resource is
permanently unavailable and has no forwarding address.

    This the problem (in web.xml):

    <url-pattern>/*</url-pattern>

    This will redirect all requests to the Spring servlet, including your request from the controller to the JSP. Essentially, the control flow will loop from your controller back into Spring again. You need to narrow that down so that the request for the JSP goes direct to the underlying container, rather than to Spring.

    Try changing it to 

    <url-pattern>/app*</url-pattern>

    And try again. You might need to fiddle a bit with leading and trailing slahes to make it work (e.g. <url-pattern>/app*</url-pattern> or @RequestMapping("hello"), etc)
