Spring 3 -- 404 error using a ModelAndView

Question

I am getting this 404 error message

The requested resource (/ghs1986/WEB-INF/pages/poll1.jsp) is not available.

from this controller method.

@RequestMapping(value = "/poll1", method = RequestMethod.POST)
public ModelAndView processPoll1(@RequestParam String vote) {
    poll1DAO.tallyVote(vote);
    ModelAndView modelAndView = new ModelAndView("PollPage");
    modelAndView.addObject("PollPage", new Cookie("poll1", "voted"));
    return modelAndView;    
}

Here is ghs1986-servlet.xml

Answer 1

Problem solved. I changed the method to return a String and returned the following:

return "redirect:/polls";
