The easiest thing to do is add a rule with a low salience (I use -1000) that will always match and add whatever action on the rhs that you want to use to signal all rules are done being processed. This rule will always be added to the end of the agenda, so when it fires, you know there are no more rules waiting to be fired.

Then I run into this issue just mentioned, can you give me some more specifics about the solution as how to determin if the engine is not busy and can safely be stopped? I'd imagine that the main thread could just wait on some semaphore the jess thread operates or call into some API which does the same thing.
