jbpm does not need a database specifically, only if you want to use persistency of states (processdefinitions can come from files to, or even strings). And even then, you *can* build your own persistency service that stores things in e.g. a file, or multiple files or whatever you come up with. You'll run into concurrency things then, but it is doable View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4149995#...
