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

Hi Bruno. I checked with the guys developing jBPM and here are some answers for you.

"
-          How is deployment going to work (hot-deployment?  files &
data required by deployment archive)?
"
we support hot deployment.  a zip file is uploaded to a servlet.  the
zip file contains the bpel and wsdl files.


"
- Are there published interfaces to run jBPM's deployment
validation or part thereof programmatically?
"
afaik, not at this point. but that should not be hard to do.
"
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 have found that uploading a zip file through a servlet is the most
flexible deployment mechanism.


"
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 are defenitely worth the consideration. our implementation,
commitment to standards and developer friendly focus make all our engine
very suitable. also our license terms are a lot more flexible then
ActiveBPEL's.


"
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. "
That would be awsome.

Hi,

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).

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.

Thanks,

james
