Sorry if the question appears little too naive. I am a Java developer with a background in Core Java, Java EE and frameworks like Hibernate, JPA etc. Now I want to learn BPM / Workflow (to add a new skillset).
What approach can I take to start learning it? Can you suggest me a good primer? Which tool should I use (I did a bit research and downloaded jBPM 5)? Where can I get the problems that I can solve? Is there any crowd sourcing activity in which I can take part to get a feel of the real BPM project?
