I'm about to implement a state machine based workflow in my app and I've encountered an interesting framework that could make this task easier - http://code.google.com/p/stateless/
Sadly, it's for C# only.
Does anyone know about a similar workflow framework for Java? I'm afraid integrating Drools would take a lot more time than I can afford, I need something lightweight like the Stateless framework.
