Re: [bpel-dev] Offer of donation of WS-BPEL implementation to assist project development

Sounds like an interesting opportunity to try and make an extracted interface for BPEL engines as I'm just starting to look at integrating Apache ODE through the ServiceMix engine, so it would be great if we could look at doing leveraging the jBPM integration.

Just to throw some stuff out there so far we have been looking at using a JBI Service Engine hot deployment to ServiceMix,  trying to look to extending of the JST/WST components to provide a JBI project,  note sure if that will be the same in jBPM but it would be sweet to be able to plug-in the engine of your choice?

Another open-source BPEL engine integrated within BPEL Designer sounds fantastic!


There are a few pieces of info about jBPM's characteristics that would help facilitate its integration into BPEL Designer:

-          How is deployment going to work (hot-deployment?  files & data required by deployment archive)?

-          Are there published interfaces to run jBPM's deployment validation or part thereof programmatically?

-          (That's all I can think of right now).


It is worth to think carefully about jBPM's requirements on deployment within the BPEL Designer so that the corresponding runtime extension point will cater for its needs. We should probably also work on a set of somewhat detailed use cases describing deployment in BPEL Designer to allow more detailed discussion and let everyone know what to expect.


We (at University College London SSE http://sse.ucl.ac.uk/omii-bpel) currently offer the ActiveBPEL engine to computational scientists and it would be great to be able to have jBPM-BPEL as a potential alternative as this would demonstrate that, when you need to rely on open-source enactment environments (in academia), it doesn't all stand or fall because of a single suitable engine.


We (UCL SSE folks) can offer to stress test jBPM to its limits and beyond with some seriously large-scale workflows to determine and hopefully help to improve its scalability characteristics.

Hello Mark,

This looks very interesting! From the jBPM-BPEL roadmap that you outline below, it looks like your dates will line up nicely with those of this project (allowing of course for whatever changes are necessary when WS-BPEL 2.0 is completed).  I believe this move will certainly benefit the community.

I'm not a lawyer so I won't comment on the license-related issues, except to say that we should get the Eclipse IP person/people to take a look and confim that it makes them happy.

Bruno: as you've taken a look at the issue of a runtime framework, I'd appreciate it if you could add any comments here.

Let's continue the discussion here of how to proceed on the design of this framework and how to carve up the work among those involved.
