Will I be able to employ Google Cloud Endpoints on a Tomcat Server (that runs as container inside Google Container Engine) by adding suitable libraries to a dynamic web project, or is this technology strictly tied to Google App Engine and can only be deployed there?

I don't require anything special in terms of authentication against Google accounts, and would just like to use the technology's annotations to implement my REST/JSON protocol in a simple (and elegant) way.

I guess the answer is no (i.e. technology is strictly tied to Google App Engine), but want to be sure before looking for alternatives.
