        System.out.println("In Index method");

        map.put("contact", new Contact());
        map.put("contactList", contactService.listContact());

        return "contact";
    }

    @RequestMapping(value = "/add", method = RequestMethod.POST)

    Contact contact, BindingResult result) {
        System.out.println("in ADD method");

        contactService.addContact(contact);

        return "redirect:/index";

}

and when i try to run the project i get the

I would be so much thankful for your precious time and help.
I am using eclipes 3.4 and jboss 4.2

Answer 1

In the site from where you are taking the code, the servlet mapping in the web.xml is done like this.

 

<servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
 </servlet-mapping>

In your code which your have posted above its like

 

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

The Url Pattern means:

/ by itself is the default servlet called if there are no other matches.

and

/* mapping in web.xml it answers all requests except other path mappings.

Check and use what you really want.
