Most of the time the wars are container-neutral, so it shouldn't be a problem, but will depend upon how far outside the norm your app server is configured. For example, in many jee app servers you can get pretty fancy w/ your security definitions, something you don't have to worry about in tomcat. So you could face issues there.
But in general I always recommend developing against tomcat. As a developer your goal should be quickly cranking out plugins, and a 'lightweight' container like tomcat w/ it's debugging facilities is the best.
That way if you do have container issues later on, they are container issues and not necessarily code or plugin issues.
