Problem with the Spring application: JspTagException

[Mike Tihonchik]

I am new to Spring MVC, and I can't seem to figure out what is the problem. I get the following exception: Neither BindingResult nor plain target object for bean name 'loginUser' available as request attribute. Here are my files: web.xml, ...-servlet.xml and LoginController.java

package controller;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;

public class LoginController extends SimpleFormController {

    @Override
    protected ModelAndView onSubmit(Object command) throws Exception {
        LoginUser login = (LoginUser) command;
        ModelAndView results = new ModelAndView(getSuccessView());
        results.addObject("loginData", login);
        return results;
    }
}

I think, I messing up in the web.xml or ...-servlet.xml while defining my urlMapping, because if I change the following line to:

<entry key="/" value-ref="loginController" />

the login page come up. Thank you in advance

Have you tried doing this in your web.xml?

     <servlet-mapping>  
         <servlet-name>i550imports</servlet-name>  
         <url-pattern>/*</url-pattern>   <<<<<<<<<< this one.
     </servlet-mapping>  

im not sure if that'll fix your problem.

Yes, I did, however, I get the following exception in my JBoss window:

16:13:24,217 ERROR [[i550imports]] Servlet.service() for servlet i550imports threw exception

hmmm haven't tried jboss before. but usually, my dispatcher servlet has this mapping.

         <servlet-mapping>    
             <servlet-name>i550imports</servlet-name>    
             <url-pattern>*.jsp</url-pattern> 
         </servlet-mapping>
