[jboss-user] [JBoss jBPM] - Re: Help on Best Practice

Ronald,

Do you mean the Business Process Management with JBoss jBPM book by Matt Cumberlidge?  I've just finished reading it and it gives a very good overview on both BPM and jBPM with a good starter application.  I would have liked to seen more developer oriented topics discussed in greater depth but given the stated audience of the book I guess that wasn't possible.

In my scenario, I need to pass business-level exceptions back immediately after some validation (from the process to the UI layer) within the context of a conversation with a user; I'm using the process as a kind of orchestration mechanism.  There are wait states later in the process but the validation step is the first.

My initial thoughts were to create a generic exception similar to SQLException where I could set a code for each business level error and then wrap a collection of these in another exception which would be thrown by my stateless session bean wrapping the jBPM engine.

Regards,
Paul.
