1. Re: What about XML databases?
kukeltje Oct 4, 2005 10:13 PM (in response to kuko)bypassing hibernate is going to take a complete redesign of jBPM. You do hover not need to store EVERYTHING in jBPM. You can store complex forms etc in the xml database and just store a reference to them in jBPM and maybe some process relevant data.

2. Re: What about XML databases?
tom.baeyens Oct 5, 2005 5:30 AM (in response to kuko)bypassing hibernate does not imply a redesign of jbpm. it requires a rewrite of all the persistence stuff (all the XxxxSession's). For your specific persistence mechanism. In case of an xml database this means that you have to implement the conversions between the jbpm objects and their xml representation. That will be a challenge if you want to make that complete. It should be quite easy to get the basics working, though.
can you enlighten us with the reason why you want the process information to be stored in an XML database ?! i'm intrigued.
also i'm interested to know how you plan to do the jbpm-java-objects mapping to xml and back again. JAXP ? JAXB ? dom4j ? or something else.

Yes, specially when time isn't on your side..."tom.baeyens@jboss.com" wrote:

We're just forced to use an XML database. If you think about it, isn't that crazy considering process-definitions and process-instances are XML documents."tom.baeyens@jboss.com" wrote:

For the conversions we've already used dom4j and jdom in other projects... as you said, not always a light task.
We'll keep on evaluating engines. If we choose jBPM you'll definitely hear from us again ;-) . Thanks for your replies.
