Org.springframework.web.servlet.DispatcherServlet Error In Migration From Spring 3.0 To Spring 3.1

I'm migrating a web application from Spring 3.0 to Spring 3.1. These are the depencies I changed in the pom, for every dependency I changed <version>3.0.3.RELEASE</version> to <version>3.1.4.RELEASE</version>:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-struts</artifactId>
  <version>3.1.4.RELEASE</version>
  <type>jar</type>
  <scope>compile</scope>

I build the package and deploy it on the server. When I do a servlet call I get the following exception:

Error 404: javax.servlet.UnavailableException: SRVE0203E: Servlet [giava]: org.springframework.web.servlet.DispatcherServlet was found, but is missing another required class. SRVE0206E: This error typically implies that the servlet was originally compiled with classes which cannot be located by the server.

My hypotesis is that there are new dependencies requirements, but which ones?

Found the mising dependencies. Searched through the poms of other projects this project was depending on and replaced all the springframework dependencies version from 3.0.3 to 3.1.4.
