The first part of the question is trivially yes: derived classes that don't provide their own main() will get your "abstract" class's main(). I guess, you knew that already. For the other part, https://stackoverflow.com/questions/939932/how-to-determine-main-class-at-runtime-in-threaded-java-application seems to imply that short of some non-reliable environment variables or system properties there is no reliable way to know which class was originally started.
