That's odd. The missing class from your exception is on the `spring-webmvc` wich is on your POM check if on the server you are running you have the `spring-webmvc-4.1.6.RELEASE.jar` on the lib folder If it is there I guess that it should be some kind of IDE cache problem on updating your server. — Jorge Campos, Jan 15 '16 at 03:17
