JSP Spring app on Tomcat not delivering page

Ok I'm stumped. I am writing a Spring based app that queries a web service for information to load a SELECT object based on the user's id. I've set up the web.xml and servlet xml files, design the initial page and have a redirect from an index.jsp file (the final system will reside under a Tomcat / IIS config) with a hard coded value for the username for the time being.

Every time I try to run it I get a 404 error and nothing in the Tomcat logs. I am relatively new to JSP / Spring so this is driving me nuts as I can't seem to find the problem.

I have tried removing the reference to the web service calls and still the pages to not load.

What am I missing?

Below is the code minus stylesheets and images:

Your controller is bound to <contextname>/search.html, not index.html - <contextname> referring to the context that Tomcat maps your application to, which usually is the name of the WAR file but can be anything if you have configured Tomcat specially.

Turn up Spring's logging and you will see it logging warnings when you request a URL that it has no mapping for.

your controller was worng, you must return a ModalAndView or NameOfView not Collection<UserDatabaseProject>

please try this :

@RequestMapping("/search.html")
   @ModelAttribute("userprojects")
   public ModelAndMap getUserProjects(@RequestParam(value="username", required=true) String psUsername){

        ModelMap modelMap = new ModelMap();
        modelMap.put("userprojects", this.dgWebService.getUserDatabaseProjects(psUsername));

        return new ModelAndView("index", modelMap);
    }

Follow any good tutorial on spring mvc. your return type should be either ModelAndView or its related type (since you are using InternalResourceViewResolved) or the String name of view.

In case of Rest Based approach or ajax you can return the data as collection (which get converted into json). For this approach you need to mark your controller as @RestController on class level or @ResponseBody on method level. This approach is mostly used in Ajax calls in which you need to iterate through the json response received and set the data on that page.

In Spring mvc based approach you need to add all the objects in the ModelAndView and set the view name as below. Then you can access the objects on that view using el.

@RequestMapping("/search.html")
@ModelAttribute("userprojects")
public ModelAndView getUserProjects(@RequestParam(value="username", required=true) String psUsername){

    ModelAndView modelAndView = new ModelAndView();
    // add all the required data which you need on next view page
    modelAndView.addObject("userprojects", this.dgWebService.getUserDatabaseProjects(psUsername));
    // set the view name which needs to be displayed
    modelAndView.setViewName("search"); 

    return modelAndView
}

In Jsp access the userprojects as:

${userprojects._msProjectName}
