Q:

Cannot Resolve Views inside WEB-INF/ folders using the jsp filename as RequestMapping value

Ok this is always a problem for spring beginners, there could be tons of similar problems out there, but every time I type this issue, I always end up reading indirect solutions which I cannot understand, just like what the title said, I cannot resolve views(jsp) inside my WEB-INF/views folder, if i map the page using the file name. 
Update: I've been searching extensively with a noHandlerFound/NoMapping Found for a URI problem, I just learned that the controller class name will be resolved by ControllerClassNameHandlerMapping removing the controller and lowercasing the non-controller name and it will be used as the url, 
but I CANT still get to load my very simple page in start-up, and no matter where I search there are always tutorials that gives the same example, it does not work. please I need help here.. :(
ProductsHomeController.java (Controller class)
@Controller
public class ProductsHomeController{

@RequestMapping(value = "/productsHome", method = RequestMethod.GET)
public ModelAndView welcome() {
    return new ModelAndView("productsHome");
}

xml configuration (XML configuration for MVC annotation and InternalResourceViewResolver)
  <mvc:annotation-driven />
<context:component-scan base-package="edu.controllers" />

<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".jsp" />
</bean>

web.xml
    <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
            /WEB-INF/applicationContext-service.xml
            /WEB-INF/applicationContext-repository.xml
    </param-value>
</context-param>

<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>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

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

Everytime I run this very simple web application on start, 
The servlet resolves the view and display the content of the page by this URL
  http://localhost:8080/ProductsHome/

but when I refresh the page, it results into a 404 error
and I need to manually type the file name of the jsp to resolve the view
  http://localhost:8080/ProductsHome/productsHome

This is the kind of code I always see in the tutorials I'm reading especially spring-recipe book, but I cannot make it work the way it was said in the book, I expect that on the first start-up the dispatcher-servlet will resolve the views and displaying the page with this URL below
how can I make this work? any help would be greatly appreciated.
  http://localhost:8080/ProductsHome/productsHome/home

here is the server log I get so far, I'm currently searching what I need to add to eclipse to show any error

A:

I thing the controller should be
@Controller
@RequestMapping(value = "/welcome")
public class WelcomeController {
@RequestMapping(method = RequestMethod.GET)
public ModelAndView welcome() {
return new ModelAndView("productsHome");
}

put the welcome-file-list in web.xml
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

in the file index.jsp , file index.jsp in the WEB-INF directory
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<% response.sendRedirect("welcome"); %>

change the servlet-mapping
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

make sure that productsHome.jsp is in the /WEB-INF/views/ directory
