spring mvc dispatcher servlet mapping

[tramwai]

Hello i have a trouble with spring mvc in jboss 7.1.1.Final. HomeController returns simple hello world jsp page.

public class WebConfig implements WebApplicationInitializer {
              @Override
              public void onStartup(ServletContext servletContext) throws ServletException {
                  AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
                  rootContext.register(ApplicationContext.class);
                  ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext));
                  dispatcher.setLoadOnStartup(1);
                  dispatcher.addMapping("/");
                  servletContext.addListener(new ContextLoaderListener(rootContext));
              }

Controller:

@Controller
public class HomeController {
    protected static final String INDEX_VIEW = "index";
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String showPage() {
        return INDEX_VIEW;
    }
}

jboss-web.xml:

<jboss-web>

    <context-root>/</context-root>

</jboss-web>

accessing localhost:8080 results in 404. I've set jboss logging to debug, and i don't see "dispatcher proccessing get request" kinda thing. Does this mean servlet is not mapped? Everything works fine on tomcat 7 and jetty 8.

And you have disabled the standard / context app and your app deployes fine?

[tramwai]

you mean this

<virtual-server name="default-host" enable-welcome-root="false">

?

Seams fine, i don't see any exceptions

[nickarls]

And you see WebApplicationInitializer being called?

(just guessing here, I'm not really a Spring-user)...

[tramwai]

when deploying i see :

(MSC service thread 1-1) Spring WebApplicationInitializers detected on classpath: [me.myself.resttest.config.WebConfig@195d568]

but i dont see calls to dispatcher servlet when accessing my app through browser

[tramwai]

Does jboss 7 support web.xml-less web-applications? Because i tried web.xml equal to my WebConfig and everything worked. Isnt this standart servlet 3.0 stuff?

I also downloaded nightly build and i'm having same problem there. Help me out please.

[nickarls]

Yes, I think it should work since Servlet 3.0 made web.xml optional

[tramwai]

Nicklas, is there any public source code that doesn't use web.xml (utilizes spring mvc preferably) and works on jboss 7?

[nickarls]

not sure about the spring-thing but if you make a foo.war with a META-INF/classes and a

@WebServlet(urlPatterns="/test")

public class Test extends HttpServlet

{

  @Override

   protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException

   {

      resp.getWriter().println("1-2-3 testing");

   }

}

you should be able to access it

I've got the same problem, I'm using Spring's AbstractAnnotationConfigDispatcherServletInitializer which should take care of registering the DispatcherServlet dynamically (not in web.xml).

I can see that DispatcherServlet is registered but anything that should be rendered via this servlet results in 404. Only static resources are available.

16:21:53,634 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/project]] (ServerService Thread Pool -- 68) Spring WebApplicationInitializers detected on classpath: [my.company.project.MyInitializer@61bc4984]

16:21:53,783 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/project]] (ServerService Thread Pool -- 68) Initializing Spring FrameworkServlet 'dispatcher'

... spring blah blah blah ...

16:21:54,896 INFO  [org.springframework.web.servlet.DispatcherServlet] (ServerService Thread Pool -- 68) FrameworkServlet 'dispatcher': initialization completed in 1111 ms

16:21:55,059 INFO  [org.jboss.as.server] (DeploymentScanner-threads - 1) JBAS018565: Replaced deployment "project.war" with deployment "project.war"

This is really strange because the same application runs fine in Tomcat 7 and Jetty 8,9...

Hi, all.

Had the same problem minutes ago. What resolved was changing dispathcer mapping from "/" to "/*"

public class WebConfig implements WebApplicationInitializer {

              @Override

              public void onStartup(ServletContext servletContext) throws ServletException {

                  AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();

                  rootContext.register(ApplicationContext.class);

                  ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext));

                  dispatcher.setLoadOnStartup(1);

                  dispatcher.addMapping("/*");

                  servletContext.addListener(new ContextLoaderListener(rootContext));

              }

    }

}

Hope this helps;
