[JBoss jBPM] - Re: Support for Dynamic Workflow Changes

by jbarrez

The long-running is not the problem, that's raison d'etre of workflow systems. The difficult thing here is indeed the changes at runtime. This is hard in any workflow system. But like I said, you can do it with jBPM, but you'll need to know the datamodel of jBPM by heart if you want to do it.

This is completely depending on your transaction configuration. But updating your domain to make jbpm work doesn't seems right to me. Can u post your config?

[JBoss jBPM] - Re: Fork/Join Problem

by freak182

Hello, I end my task like this: wfEngine.signal(wfTask.path.id, null); wfEngine.endTask(taskInstanceId, null); but i already solve my problem. What happened is this: anonymous wrote : 7.7. Combining your hibernate classes | | In your project, you might use hibernate for your persistence. Combining your persistent classes with the jBPM persistent classes is optional. There are two major benefits when combining your hibernate persistence with jBPM's hibernate persistence: | | First, session, connection and transaction management become easier. By combining jBPM and your persistence into one hibernate session factory, there is one hibernate session, one jdbc connection that handles both yours and jBPM's persistence. So automatically the jBPM updates are in the same transaction as the updates to your own domain model. This can eliminates the need for using a transaction manager. | | Secondly, this enable you to drop your hibernatable persistent object in to the process variables without any further hassle. | | The easiest way to integrate your persistent classes with the jBPM persistent classes is by creating one central hibernate.cfg.xml. You can take the jBPM src/config.files/hibernate.cfg.xml as a starting point and add references to your own hibernate mapping files in there. I perform an update to the persistence class in my domain model before it work fine. Now my question is, do i have always perform an update or any transaction in my domain model before committing the jbpm transaction? Is there a way that i dont have to perform transaction in my domain model but still jbpm will work just fine? Thanks a lot. Cheers.

[JBoss jBPM] - Re: Support for Dynamic Workflow Changes

Thanks for quick response. Well, our project is developing an methodology for modelbase software integration. This results in a toolkit / framework. Due to the complexity of the developed procees, we intend to integrate a workflow component for user guidance and project-management purposes. This process will be very long-running, i know not ideal for wfms, and has to be flexible as well. Changes to a project flow are to be expected. For that purpose dynamic workflow is needed.

[JBoss jBPM] - Re: Support for Dynamic Workflow Changes

by jbarrez

It is possible. In the end its a matter of database manipulations, but I've never done it myself. Otoh, you should make out for yourself is this 'dynamic workflow' really is needed. Workflow systems are used to make people do the same, company-wide. If some people do need to do other things (ie what you call dynamic), then this should be modeled in your flow. If you want to do ad-hoc changes to your flow, what's the added value? Your KPI's will be useless and maintenance will become a hell. So, yes, I'm not a fan of dynamic workflows ;-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4233849#4233849 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4233849

[JBoss jBPM] - Support for Dynamic Workflow Changes

by MariusMeuser

Hi, I am currently evaluating jBPM as a candidate technology for some implementation-work. A special requirement from project-side is to be able to do dynamic workflow changes. That means, to change workflowdefinition during enactment and propagate changes to running instances. I worked through the docs but didnt find a hint about that feature. So here goes my question: Does jBPM support dynamic workflow changes somehow or is it possible to reach that requirement with some implementation work ?

[JBoss jBPM] - Running JBPM on WebSpere 7

by jokum

Hi all, Does somebody have any best practices or experiences on running JBPM on WAS 7? I found this document : http://www.jboss.org/community/wiki/Jbpm32OnWAS61 describing how to get het jbpm console running on WAS. But what I need is information on how to initialize the process engine and deploy processes to it. Kind regards View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4233833#4233833 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4233833
