[news.eclipse.technology.jwt] Re: JWT in Eclipse Galileo

lautenbacher@xxxxxxx (Florian Lautenbacher) — Thu, 30 Jul 2009 13:35:19 GMT

Just as a short add-on to this announcement: the announcement of one of the standalone RCP-applications on top of JWT:

It's already a while since the newest release of Eclipse with codename Galileo has been released. This contained the newest version of the Java Workflow Tooling (JWT) project. JWT is also the basis of the AgilPro project which is a standalone RCP application that integrates all plugins of the JWT release 0.6 but also additional features such as a BPEL-codegeneration or a simulation of the processes.

Therefore, I am happy to announce that the newest version of AgilPro (v1.6.0) has been released and is now available on SourceForge. The AgilPro tool suite can be downloaded under the GPL at https://sourceforge.net/projects/agilpro.

The new features of JWT have been described in an IBM developerWorks article [1], the project JWT has been summarized by Ian Skerrett (Eclipse Foundation) in his blog [2] and there was also an article about JWT in the German speaking Eclipse magazine [3].

The most important features of JWT 0.6 and also of AgilPro 1.6.0 are new views, e.g. UML activity diagrams or Event-driven process chains (EPC), BPMN interoperability, several new code generations (e.g. XPDL) and the collaboration with the friend SOA Tools Plattform (STP) project by integration of an STP-IM-transformation and building an own SOA-focused integrator named Scarbo as part of the OW2 consortium. Quite important for the last release was also the aspect-oriented extension mechanism that is now part of JWT which allows vendors to easily extend the JWT metamodel.

As last time, I'd like to say thanks to the whole project team for their support and assistance!

If you have any feedback or comments, please don't hesitate to publish them as a bug on the Eclipse Bugzilla (see www.eclipse.org/jwt) or contact us here.

Hi Florian

Thanks a lot for the infos. I installed the Scarbo part using the http://scarbo.ow2.org/update-site/ site, as recommended by Mickael. Maybe it would be helpful for users if there is a link on the http://wiki.eclipse.org/JWT_Downloads page?

Right now I'm using the Bonita Runtime to manage my workflows in Eclipse. I would have used your JWT runtime but Bonita does it for now (too bad it's not OSGi based :-( ).

Flavio

Hi Flavio,

the export to Bonita BAR is not contributed to Eclipse yet. As there are some licensing issues between EPL and LGPL, it probably never will. As you maybe have also seen on the presentation of Eclipse Forum [1], the support for Bonita 4 is maintained in the OW2-project Scarbo [2]. There you can find all the plugins and some further documentation.

Another question, is or will there be a JWT runtime? I can't find any documentation nor a download for it, even though there is a empty wiki page: http://wiki.eclipse.org/JWT_Runtime

JWT aims to support existing runtime environments with generic implementations and support projects to adapt their runtime to these frameworks (as we do in Scarbo). So for the moment being there will be no own process engine, if you mean that. But we are working on a runtime for executing/simulating/previewing a workflow directly in Eclipse. This will become the JWT Desktop component, but won't be finished for the Galileo release.

Best regards,

Florian

[news.eclipse.technology.jwt] Export JWT to Bonita4 BAR

flavio.donze@xxxxxxx (Flavio Donzé) — Fri, 08 May 2009 12:16:00 GMT

Hello

I'm want to use Bonita as workflow runtime. In the screen cast http://www.eclipse.org/jwt/press/eclipsecon09/EclipseCon09Example.swf there is an export shown "Export JWT to Bonita4 BAR", but in the current version I downloaded through http://download.eclipse.org/technology/jwt/stable-update-site/ I don't have this option.

Is the screen cast out of date or ahead of date :-) ?
Are there any requirements on the workflow for a BAR export?

Another question, is or will there be a JWT runtime? I can't find any documentation nor a download for it, even though there is a empty wiki page: http://wiki.eclipse.org/JWT_Runtime

greets and thanks in advance

Thank you all for all this pieces of informations !

I am going to see further this imixs, but i wish JWT will arrived soon to what it is promise !

I gonna look at xforms and bonita also.

lautenbacher@xxxxxxx (Florian Lautenbacher) — Wed, 18 Feb 2009 16:59:46 GMT

Hi Jogrey, hi Mickael,

First, the AgilPro Simulator is a desktop tool that actually executes the process (and not only simulates it), but without the use of a process engine below. This means it can't handle multiple instances of the same process. I agree that using existing process engines sometimes is a lot of overhead, but for bigger processes with thousands of instances it is alas not possible otherwise. My first thought concerning your question has been the Process Virtual Machine (PVM) [1] that is the basis for JBPM as well as Bull Nova Bonita. If you are searching for an API then this might be the place. On the other side, Mickael is also working on the tooling side (as he already mentioned) and thereby concerned about a minimal set of API (an image can be seen at [2]). Maybe that might be something that is interesting for you?

But both are not concerned about a presentation layer for asking questions, etc. Maybe imixs [3] might be interesting for you, I believe to remember that they got something like that in their tooling.

That's all for the moment I can think of, so I'm sorry if I was not able to help you at the current state.

Regards,

Florian

Hi Jogrey,

I understand your frustration. There is indeed a gap between BPM/workflow engines, that are technical solutions, and a complete high-level BPM solution with a set of useful connector, etc... Be sure of one thing: a lot of work is currently being done in that sense,

I think that with the last version of Bonita (with eXo console) you have the ability to map custom forms to task, using XForm. However I don't know whether it fits to your need.

Unfortunately, JWT project has not currently focused on what I'd call the "presentation" topic yet, but I agree with you that the "presentation" could have its place into JWT. Having a presentation topic would be a first stop to making JWT become a "BPM solution Studio". That sounds nice ;)

However, in its current state, I can't figure how JWT may help you. Maybe AgilPro contains pieces of answers...

Let's wait for Florian passing by the newsgroup, his knowledge of AgilPro will probably be useful ;)

Regards,
Mickael

Jogrey a écrit :

Hi,
I recently used the JBPM API, it was very simple and well documented, enougth to use it in a small application.

But, i am a bit disapointed by all BPM systems, as their engine are not bundled with very standart components as a class to open a document, or to ask user a question, to transform a simple decision node into a simple web form. The only thing approching this dreaming vision is AgilPro Simulator, but as it's told, it's only a simulator. I aslo tried Bonita, but seems very complicated to plug a lot of services to display a simple decision listbox and display a poor word document.

Like the JBPM API, maybe by JXT is proposing an API i haven't still found ? If it's the case i will certainly use it to create my simple workflow engine under tomcat and with GWT as presentation.

Is this kind of project crazy at the actual hour with the actual state of the JWT project ? Is that kind of project already existing ( to join it of course) ? Thank you in advance.
