Hi drivexcite,

Seam 2.2 does not support pageflow with jBPM 4.1, but they are working together.
You can use jBPM 3 and 4 in parallel.

Your exception is because you replaced the jbpm-jpdl.jar, so Seam can not find jBPM3. 
So leave this jar file, or disable jBPM for Seam in components.xml by removing

<bpm:jbpm />

I disabled jBPM3 in my application and the server is starting up, 
I can use jBPM.

My problem is, that jBPM and Seam are using two different Hibernate sessions, 
so I can not store my entities as jBPM variables (jBPM does not recognize my class as entity, so it serialises it as a blob).

I the first post I described my attempt to solve this. It's working, 
but some transaction does not commit ... I think I have to take 
the  warning "Can not join ..." seriously.

In my further investigation I figured out, that jBPM is using 
JTA Transactions and my Application uses CMT Transactions. 
My knowledge about this is not that good. 
I will have to do more analyses.

Best regards,
