Can't force Spring Web MVC 3.0 framework to work

I'm building a Web application with Java. Trying to integrate Spring Web MVC 3.0 framework. But I can't even force simply to show the page. I am using NetBeans 7.0 and Tomcat 6.0. This is what I've got: Web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.htm</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
    <welcome-file-list>
        <welcome-file>redirect.jsp</welcome-file>
    </welcome-file-list>
</web-app>

Dispatcher-servlet.xml:

    <!--

        <property name="mappings">

    <bean name="indexController"
          class="org.springframework.web.servlet.mvc.ParameterizableViewController"
          p:viewName="index" />


</beans>

Controller:

package forum.web;

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


/**
 *
 * @author 
 */
@Controller
public class RegistrationController
{
    @RequestMapping("/registration.htm")
    public ModelAndView registrationWindow() 
    {       
        return new ModelAndView("registration");
    }
}

XHTML page:

<tr id="log_reg">
      <td>
          <a href="login.htm"> Log in </a>
          </td>
      <td></td>
      <td>
        <a href="registration.htm"> Register </a>
        </td>
   </tr>

Running this command I see index page:

http://localhost:8088/Forum/index.htm   

On the page I click the link, what suppose to open registration page. But instead is I see HTTP 404 error. The link:

http://localhost:8088/Forum/registration.htm

Found errors on NetBeans:

18-Jun-2011 14:45:19 org.springframework.web.servlet.handler.AbstractUrlHandlerMapping registerHandler
INFO: Mapped URL path [/index.htm] onto handler [org.springframework.web.servlet.mvc.ParameterizableViewController@1fb0fc2]

I can't release the cause of these errors. Code looks fine, in my opinion. I tried many things by this time. Any help? Best regards

Probably it's because you use both annotation mapping and SimpleUrlHandlerMapping.

Try to add bean:

<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotat ion.DefaultAnnotationHandlerMapping">
</bean>

and add it as a handler to your urlMapping bean:

<property name="interceptors">
   <list>
     <ref bean="handlerMapping"/>
   </list>
</property>

It's easier to use only one of them, especially annotation based controllers. At this case you have to throw out your urlMapping bean, and instead of indexController bean use simple class like:

@Controller
class PagesCtrl {
    @RequestMapping("/index.htm")
    ModelAndView index() {
        ModelAndView mav = new ModelAndView("index")
        return mav
    }
}
