Hi Mike > I'm not aware of any. I am kind of developing my own for my current > Materials System. Sounds as though, like me, you might just get away with a decision table parser rather than a fully-fledged corporate rules engine. though your application is a bit more complex than ours. It's surprising to me that we are faced with rolling our own or working with Java - suggests that PHP still has a bit to go as a platform for serious business systems. > With jBPM I "hope" I'll be able to change "routing"/approval of > electronic documents more easily than it is currently. Are you planning to have PHP run as a servelet within JBoss? Does this work reliably? I much prefer to keep things as simple as possible. As an alternative, I worked briefly on a native PHP Petri-net workflow engine with a guy called Tony Marston before we parted ways.
