Newb question. I am just starting out with drools-jbpm (6.1.0) and have successfully loaded/ran some OSGI example apps using Karaf (3.0.1) as the OSGI container. I am looking for pointers on where to start to understand how to configure the drools-jbpm services for JPA/JTA persistence. I understand the basics of stand-along db configuration. But I'm unsure how to get started translating that to OSGI base service configuration. Looking for any and all pointers. Working examples preferred.
