regards.

It looks like you have a class gest_project.model.metier.ActeurServiceImp, which I'm guessing uses a @Service or maybe @Component annotation to make it a Spring bean, and it looks like it implements an interface named gest_project.model.metier.ActeurService. That interface isn't available to your app, hence the NoClassDefFoundError.
