[JBoss jBPM] - Jbpm seam webapp and jbpmconsole deployment order issue

by fransja

Hi, I am using the Jbpm-enterprise ear, which is a littte modified to enable the use of seam together with the jbpm console. Then I have my own ear file which contains some ejb's and a webapp, which talks to a jbpm process (my application...). Build for JBoss 4.2.2 and seam 2.0.1, jbpm-jpdl-3.2.3 Now comes the weird thing: When I deploy the the webapp before the jbpm-enterprise ear the webapp works... When I deploy the jbpm-enterprise ear first the jbpm process works, but the webapp issues the error: Error loading jbpm configuration: null (I can't get a logging furter than this, tried everything...) When I go the the .../jbpm-console and do a refresh (not logging in) and then again go the the webapp it works! Anyone a suggestion where to look further?

[JBoss jBPM] - Using EJB3 transactions with jBPM

by vanyatka

Hi, I've we got the situation where the first node of my business process starts EJB3 transaction and the last node either commits it or rolls back. The problem I have now is that each action seems to be transactional, in other words all JPA operations that reside in the SLSB actions turn out to be persistent after the action method ends. Can anyone suggest how to organize proper transaction demarcation with jBPM, or is it purely EJB3 & Seam issue?

[JBoss jBPM] - Re: Using variables in Expressions

by kukeltje

If you've used google, you probably found: http://www.google.nl/search?q=jbpm+el+examples&ie=utf-8&oe=utf-8&aq=t&rls... As mentioned before and you conclusion from the docs, the plain jBPM EL resolver is kind of minimalistic but to a large extend does it's job. The resolver in jBPM is pluggable though, that is the way you get access to the Seam backend beans. More examples in this area would also be nice View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4169723#4169723 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4169723

[JBoss jBPM] - Re: Using variables in Expressions

by vanyatka

I'm a bit put down seeing lack of information on using EL in jBPM. The maximum I could find is a chapter Expressions http://docs.jboss.org/jbpm/v3/userguide/jpdl.html#expressions in the jbpm reference guide. There is not a single mentioning of how to use them among jBPM examples. Sure, there are pieces of code scattered through Internet and searchable by Google, but it feels sorta wrong learning stuff that way, it is inconsistent. It would be nice to see more EL examples in the manual, I guess I might raise a feature request if I'm not alone on this. Especially this applies to using jBPM with Seam (as stated towards the end of the above mentioned chapter).

[JBoss jBPM] - Re: Deployment of Process Definition

by kukeltje

this should work.. it is the same way that the console does it. So please make a unit test that demonstrates the problem View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4169569#4169569 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4169569

[JBoss jBPM] - Re: Process state issue

by vinodkv

Sorry for the naming convention, it is from an example that i found online . Have done the deployment in the same manner. Ths inner process first and the sub process later. It goes to the Inner Process task and stays there but it does not execute anything under it. If you signal the flow it goes ahead and completes the process flow. Is there any other way to do it ??

[JBoss jBPM] - Re: process variables out of session

by frantisek.kocun＠gmail.com

Solved. My problem was that incoming variables form client were detached from session. So I attached them with saveOrUpdate method. When I read a process variable in ActionHandler it is always registered. So there was no problem.

[JBoss jBPM] - Re: Deployment of Process Definition

by ragna

Thanks for the reply! I also tried | JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext(); | try { | ProcessDefinition emailProcess = ProcessDefinition.parseXmlResource("doorprocess/processdefinition.xml"); | // jbpmContext.deployProcessDefinition(emailProcess); | jbpmContext.getGraphSession().saveProcessDefinition(emailProcess); | } finally { | jbpmContext.close(); | } | with the deploy line commented in and out, with always the same result. I also tried first making an archive and read this with no more success. Is there another way to save the process definition?

[JBoss jBPM] - Re: purge data after processinstance reaches end ?

by lblaauw

Hey, Yeah I am aware of this function call, question remains though where to call it.. Ideally I would like the process at the end to purge its own data. Offcourse it could be purged through an external process running outside of jBPM but thats not really a great way in my view, i.e. another process to worry about.. So I will try from the process end, but no idea what will happen if a process purges its own data right before it ends ?
