Global is probably how I'd do it. Now, outside the rules you might want to get fancy, like IOC or a ThreadLocal, but inside a global is fine. (unless you're in multithreaded mode with a single hibernate session, which is bad because hibernate sessions are not thread safe.)

So if you need to execute more than one db transaction in one rule firing session, then pass in a hibernate SessionFactory to spawn multiple hibernate Sessions. Otherwise pass in a hibernate Session.

I am wondering if there is some standard practices on how one should reference the Hibernate Session inside a rule. Should this be passed in as a global variable? Is there a better way of doing this? Any advice on this would be greatly appreciated.
