[jbpm-dev] jBPM5 Request for Comments

[McManus,Alexander]

We're using jBPM 4 at the PVM level to support a Groovy-based
domain-specific process language. In any new version, I'd like to see
the PVM API more formally defined and documented - at the moment it
feels like we are taking a risk messing about in the internals of jBPM.
Perhaps the PVM could be a separate sub-project in its own right? This
hard separation might also help improve its design - it seems to be
getting more muddled with each release of jBPM 4, for example exposing
implementation classes in APIs rather than the interfaces they
implement.

I'd also like to see the back of the strange
dependency-injection/configuration framework in jBPM, and be able to use
any DI framework (e.g. Spring) to fully configure jBPM.

Thanks, Alex.

Subject: [jbpm-dev] jBPM5 Request for Comments

Over the last few years, we have accumulated a lot of knowledge and 
experience in various BPM-related projects here at JBoss, and in an 
effort to consolidate that, we would like to combine our efforts in what

will be the next generation BPM platform, called jBPM5.

jBPM5 will be based on the combined experience of jBPM and Drools Flow 
(and related projects like RiftSaw and Overlord), and will bring 
together the benefits of both solutions (and much more). As part of this

process, we would like to ask you, our community, for feedback and 
assistance on this.

The architecture of jBPM5 builds on the experience that was built up 
over the past few years based on our customer feedback as well as strong

community involvement. It will continue the vision of all of the 
constituent projects, so large parts of the architecture that is 
presented here will probably not come as a surprise to you, either 
because it already exists in a current project or because it has been on

the roadmap for quite some time (e.g. BPMN2).

Nevertheless, wide feedback is very important to us, and we have 
therefore constructed a "Request for Comments" document which describes 
(what we believe could be) the new architecture of jBPM5. Now is the 
time for the community that has helped shape these projects so well in 
the past to do so again.

http://community.jboss.org/wiki/jBPM5RequestforComments

This not only includes an overview of the most important components, but

also some of the key characteristics. Based on this architecture (and 
the feedback we receive), we will roll out a roadmap for jBPM5.

We would like to welcome any feedback feedback on this proposal, using 
the jbpm-dev at lists.jboss.org mailing list, or in private by sending your

comments to your JBoss contact. If you want to subscribe to the jbpm-dev

mailing list or browse the archive, use:
