[jbpm-dev] Storing process state in external entities

Hi, dear developers, I would love to use jBPM5. However, I need a way to store the state of the process instances in external entities. Is this possible with jBPM5, or is there an extension mechanism I can use to implement that? And can I define process instances externally, that means, without having to replicate my existing processes in jBPM, but just by providing an adapter that tells jBPM which processes are currently running?
