Spring MVC and Apache Tiles - 404 error

Question

I've written "Hello World" website with Spring 3 MVC, now I'm trying to rewrite it using Apache Tiles technology. I'm using Maven to build my project. pom.xml

HomeController.java

package com.michat.controller;

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

@Controller
public class HomeController {

    @RequestMapping("/")
    public String showHomePage() {
        return "home";
    }
}

I have footer.jsp, home.jsp, header.jsp and layout.jsp defined in views directory in WEB-INF. Why am I getting this error?

From what you've posted, we can't tell if you have any controller handler methods. Do you? — Sotirios Delimanolis

Please add to your dispatcher.servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xsi:schemaLocation="
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.2.xsd">

<context:annotation-config />
<mvc:annotation-driven />
<context:component-scan base-package="com.michat" />

<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView" />
</bean>

<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
    <property name="definitions">
        <value>/WEB-INF/tiles-defs.xml</value>
    </property>
</bean>

This

<context:annotation-config/>

will activate various annotations like @Required and @Autowired

This

<mvc:annotation-driven />

is needed to have annotation driven controller.

Below configuration simply scans the classpath for annotated components.

<context:component-scan base-package="com.antenna.nn.patient" />

UrlBasedViewResolver is viewResolver that allows for direct resolution of symbolic view names to URLs. Tiles is needs this.
