[rules-users] jbpm and rule flow

Hi All, I'm a bit confused regarding the differences between the two. I understand that JBPM is a complete workflow with full workflow capabilities. But will the rule-flows continue to work? I've created a sample rule-flow, but it doesn't work until I put the jbpm jars in the classpath. I can remember in older versions of drools I never used to import these jars seperately. Is it recommended to continue writing rule-flows with the latest versions?? I'll be grateful if someone can provide me a link where I can get my confusions cleared. Thanks in advance -- cheers Sumatheja Dasararaju
