Unable to locate Spring NamespaceHandler for XML schema namespace Application-Context

I'm developing an GWT web app using some Spring libraries. I use Maven to include my dependencies.

Here's my pom.xml :

Here's my application-context.xml :

Everything is ok but when I include the Spring-Web dependency. I have a problem starting the project. The following exception occurs :

 [WARN] Failed startup of context c.g.g.d.s.j.WebAppContextWithReload{/,file:/D:/Users/Yeap/workspace-sts 3.6.2.RELEASE/testproject/target/testproject-0.0.1-SNAPSHOT/},D:\Users\Yeap\workspace-sts 3.6.2.RELEASE\testproject\target\testproject-0.0.1-SNAPSHOT org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://ift.tt/1iMF6wA] Offending resource: ServletContext resource [/WEB-INF/application-context.xml]

I don't understand where the problem is... I thought about a SchemaLocation Namespace issue but I've tried all the versions possibilities and not a single is good.

Thank you in advance for the help
