I'm doing some tests with the jboss 7 + spring mvc, and locally it runs but when I put in the cloud, it features HTTP Status 404.

/pswebproj/src/main/java/pswebproj/control/HelloController.java

package pswebproj.control;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/hello")
// URL Controlador 
// - http://localhost:8080/pswebproj/spring/hello
public class HelloController
{
    @RequestMapping("/simple") // .../pswebproj/spring/hello/simple
    public ModelAndView helloRequest()
    {
        String model = "Message from helloRequest(), UAU!";

        ModelAndView mv = new ModelAndView("/hellospring.jsp");
        mv.addObject("msg", model);
        return mv;
    }

    @RequestMapping("/param") // .../pswebproj/spring/hello/param?prm=sbrubbles
    public ModelAndView helloRequestParam(@RequestParam String prm)
    {
        String model = "Message from helloRequestParam() "+prm;

        ModelAndView mv = new ModelAndView("/hellospring.jsp");
        mv.addObject("msg", model);
        return mv;
    }

    @RequestMapping(value="/pathvar/{var}") 
    //.../pswebproj/spring/hello/pathvar/sbrubbles
    public ModelAndView helloRequestPath(@PathVariable String var)
    {
        String model = "Message from helloRequestPath() "+var;

        ModelAndView mv = new ModelAndView("/hellospring.jsp");
        mv.addObject("msg",model);
        return mv;
    }   
}

I m using local jdk1.7.0_80 + tomcat 7 . And I can run site with the url http://localhost:8080/pswebproj/spring/hello/simple

The output is :

Java Puro: Message from helloRequest(), UAU!
JSTL: Message from helloRequest(), UAU!
EL: Message from helloRequest(), UAU!

But if I run in the cloud with http://pswebproj-drinith.rhcloud.com/spring/hello/simple , I have the answer HTTP Status 404.

have you checked the log files of your app server in the cloud to ensure your deployment was successful ? – guilhebl

Spring container has NOT detected your Controller class as you have missed the contextConfigLocation path which should point to WEB-INF/springweb-servlet.xml for the DispatcherServlet, you need to add it as shown below in your web.xml file:

<servlet>
   <servlet-name>dispatcher</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>WEB-INF/springweb-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

People don't know what could have happened, redoing the tests to show my teacher, he asked to see the output of the console on the server and looking didn't see nor an error output when I was testing with the normal url again just ran, I don't remember having changed nothing.

Thanks to the forum anyway.
