BeanCreationException - Worked before, not anymore

I have a project which is working locally, but when I try to deploy it to a tomcat 7 server, it gets the following exception:

What is the cause of this? I haven't edited anything.. It works locally, but not deployed...
EDIT 1
Added full stacktrace
EDIT 2
This is not a version mismatch error, since I've changed the tomcat version on my IDE to 6.0 (which is also the tomcat version on the server that I'm trying to deploy to). Please help..

You have some classloading issues. java.lang.UnsupportedClassVersionError is reported for class se.kth.webservices.rest.CategoryController (also for CheopsController) which means you have multiple versions of the class in the container. Maybe an older version is deployed on Tomcat?
EDIT
I didn't read the exception well enough, so I mislead you. peter.petrov is right, this is a Java version issue. Your project was compiled with Java 8, and your Tomcat servers are running on some previous Java version. You should compile your project with the same Java version as the server you plan to deploy it on is running on, or some previous version, since Java is backward compatible.

This indicates class incompatibility. You should make sure the client has the same versions of the classes as the server. If you do a Google search for "unsupported major minor version" or "Java unsupported major minor version", you'll get a lot of hits (from SO too).
