Document root element "beans", must match DOCTYPE root "null"

I've got an xml parsing error that I can't manage to track down. The error appear when tomcat try to start a spring 3 web application.

Here is the full stack trace as seen in server logs:

org.springframework.web.context.ContextLoader.initWebApplicationContext Context initialization failed
 org.springframework.beans.factory.BeanDefinitionStoreException: Line 4 in XML document from ServletContext resource [/WEB-INF/applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException: L'élément racine de document "beans" doit correspondre à la racine DOCTYPE "null".

And here is the applicationContext.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
    xmlns:context="http://ift.tt/GArMu7"
    xmlns:mvc="http://ift.tt/1bHqwjR" xmlns:xsi="http://ift.tt/ra1lAU"
    xsi:schemaLocation="

        http://ift.tt/QEDs1e
        http://ift.tt/GArMu7
        http://ift.tt/QEDs1k
        http://ift.tt/1bHqwjR
        http://ift.tt/1bVJL9q">
    <context:component-scan base-package="com.mkyong.common.controller" />
    <mvc:annotation-driven />
</beans>

By the way here is my pom.xml file (I've allready checked spring framework versions):

<properties>
    <spring.version>3.0.5.RELEASE</spring.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>
</dependencies>

I've tryed reloading maven dependencies, tryed with various things (for example an empty applicationContext.xml file) but it always give me the same error. The application doesn't even show up in tomcat's manager.

Can some point me in the right direction to fix this error?
