Hi, I followed the instructions on setting up the persistence in the
drools flow doc, but I get the following exception:
Exception in thread "main" java.lang.RuntimeException: Could not commit

I have no idea what this means. I guess SingleSessionCommandService is
looking up for "UserTransaction", but whats the "UserTransaction" ?
Cheers, Rob.
