I am learning right now Spring, so I'm facing above problems, so please provide me a solution, I will use Annotations later after when I understood this issue..

HI, I tried as you said, BUT still iam getting same errors, BTW I have updated above my stacktrace... pls chk it, if possible please run from your end.. — Irwin, May 27 '13 at 08:19
Have you seen this post? http://stackoverflow.com/questions/11014782/adding-context-loader-listener-to-web-xml-in-spring-mvc — Angelo Fuchs, May 27 '13 at 08:22
you're saying me to remove '/' from this tag, right??? , HERE: I did as you said, BUT still iam getting same errors as above....I tried using BOTH forms.. iam not understanding what still changes need to do, can u find any other errors in my xml files? — Irwin, May 27 '13 at 08:32
I seen your link, BUT i have "contextConfigLocation" inside , instead of using , so am I doing wrong here? — Irwin, May 27 '13 at 08:34
You've edited your question to where it no longer reflects reality. You claim to receive an error that your code won't generate. If your original question is answered, you should accept the answer and ask another question if you have one. — Ryan Stewart, May 27 '13 at 16:52
too much problem, you better create different questions for differents problems. — storm_buster, May 27 '13 at 17:40

I recommend the following links:

http://duckranger.com/2012/04/spring-mvc-dispatcherservlet/

http://viralpatel.net/blogs/spring-3-mvc-handling-forms/

http://static.springsource.org/spring/docs/2.0.x/reference/mvc.html

And this setup worked for me:

web.xml

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.htm</url-pattern>
    </servlet-mapping>
    [...]
</web-app>

application-context.xml

<beans xmlns="http://www.springframework.org/schema/beans">
    <import resource="myOtherContext.xml"/>
</beans>

myOtherContext.xml (for the sake of having some import)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean name="login" class="test.LoginController"/>
</beans>

dispatcher-context.xml (Note that this is auto-addressed because my dispatcher servlet is called dispatcher and it appends -context.xml automatically)

login.jsp

LoginController.java

public class LoginController extends SimpleFormController {

    public LoginController() {
        setCommandClass(User.class);
        setCommandName("user");
    }

    @Override
    protected org.springframework.web.servlet.ModelAndView showForm(HttpServletRequest request, HttpServletResponse response, BindException errors, Map controlModel) throws Exception {

        return super.showForm(request, response, errors, controlModel);
    }

    @Override
    protected ModelAndView onSubmit(Object obj) throws ServletException {

        User user = (User) obj;
        System.out.println("username: " + user.getUname());
        return new ModelAndView("index", "user", user);
    }
}

so, cant we use an application without using application-context.xml file? is it a MUST file?? BTW, i run with your above code and will let you know now.. — Irwin, May 27 '13 at 08:38
BTW, should I neeed to use this? org.springframework.web.context.ContextLoaderListener in this link given: http://stackoverflow.com/questions/7704286/java-lang-illegalstateexception-no-webapplicationcontext-found-no-contextloade — Irwin, May 27 '13 at 08:39
No, its not. You can use the import statements in every context.xml. It is convention to name the top level context.xml `application-context.xml` and work down from there. — Angelo Fuchs, May 27 '13 at 08:40
@Irwin Please have a read of http://duckranger.com/2012/04/spring-mvc-dispatcherservlet/ to get to know what the DispatcherServlet does and how (etc.) I edited into my answer as well. — Angelo Fuchs, May 27 '13 at 08:50
sure, i will definitely read that link, now iam having a doubt, should I use imports now, since iam using ContextLoaderListener, if u dont mind, can u just show me the code of yours application-context.xml and , web.xml file (full UPDATED code) — Irwin, May 27 '13 at 08:57
@Irwin I have not run your code, yet. I might if the suggestions I gave you don't yield the result. When I do, I'll give you the codes. But when you learn a new technique its important to work yourself into it. — Angelo Fuchs, May 27 '13 at 09:05
atleast can u tell me , should I need to use import tags now, since iam using a Listeneer, right? — Irwin, May 27 '13 at 09:07
I just updated web.xml, application-context.xml, controllers-beans.xml files in my 1st post, now when I try to run using , iam getting this exception: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'user' available as request attribute — Irwin, May 27 '13 at 09:32
let us [continue this discussion in chat](http://chat.stackoverflow.com/rooms/30676/discussion-between-angelo-neuschitzer-and-irwin) — Angelo Fuchs, May 27 '13 at 09:34
when iam using with normal form tag, iam getting same 404 error for the url: http://localhost:8443/BugTrackingSystem/login (this url comes after when I submitted my form) — Irwin, May 27 '13 at 09:35
I tried with your updated code, BUT iam still getting same exception: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'user' available as request attribute — Irwin, May 27 '13 at 14:53
@Irwin Then, I'm sorry, I can't help you any further. This code of mine is a working example. It actually runs over here. So whatever you do, it must be something different then what I did. Please create a new Example Project and add exactly the code as I provided it and test it again. — Angelo Fuchs, May 27 '13 at 16:50
HI, iam using now Annotations, iam getting same exception even using annotations also, can u please check my code here: http://stackoverflow.com/questions/16777156/java-lang-illegalstateexception-neither-bindingresult-nor-plain-target-object-f/16789190?noredirect=1#16789190 — Irwin, May 28 '13 at 14:01
