Unable to locate Spring Namespace Handler for XML schema namespace

I got a problem with loading my Dynamic Web Project in Eclipse. I'm using Spring and Struts frameworks for it.

Here's the error message. It seems that the tomcat server cannot find the Spring NamespaceHandler. :(

Console:

ERROR [localhost-startStop-1] (ContextLoader.java:331) - Context initialization failed
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://ift.tt/OGfeU2]

Can somebody give some tips ? Because I've spent a lots of time but there was nothing I could do...

What I've tried:

• include the spring-tx dependency in pom.file
• Maven -> Update project
• Run as Maven clean
• Run as Maven install
• restart the computer
