[jBPM Users] - jBPM 4: what are the performance improvements?

by bwestrich

Hello jBPM gurus, We are using jPDL 3.2.3 for a high volume transaction processing system. We want to wring as much performance out of jPDL as possible. The announcement for jBPM 4.0 (http://www.theserverside.com/news/thread.tss?thread_id=55178) mentions performance improvements, but doesn't provide further details. Could someone point me to links to the details on these improvements? This could be a big help for us in justifying an upgrade to 4.0.

[jBPM Users] - Re: Ending task with timer - session is closed

by alex.guizar＠jboss.com

Seems like an instance of JBPM-1135. By disabling the current session, jBPM is creating a separate session rather than using the existing one, which explains why your modified configuration works. It may not employ resources in the most efficient manner, tough. I would suggest upgrading to jBPM 3.2.4 or later, but I realize Seam is pinning jBPM on version 3.2.2. The only real soution would be to have the Seam guys upgrade to a later version of jBPM.

How does your process definition look like, and how do you start the process? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4259432#4259432 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4259432

[jBPM Users] - [jBPM4] Synchronous process execution

by c4s4l

Hi all, I'm starting a process with executionService.startProcessInstanceByKey(...) and I want to wait for its end (without polling isEnded()), how can I do this? I've inspected the ProcessInstance, Execution API's and cannot find anything related to this. I just want to run a process Synchronously.

[jBPM Users] - Accessing the current task of a ProcessInstance and/or his s

by shiva0

So, I'm slowly starting to get the feel of the jbpm engine. But I've hit a brick wall... well found a bypass but let's start at the beggining. One process contains multiple subprocesses. I need to be able to fetch the list of all tasks associated to the "Master ProcessInstance". I've tried going thru the Execution query but I could never find how I can start from my ProcessInstance and access the sub-process execution without knowing it's specific ID. Until I started looking at the ExecutionImpl binding with the database. There is a getSubProcessInstance() method that is not available on the Execution interface. I could just cast and access it, but is there probably a reason it's not made available. So, how can I do what I need without that casting patch?

[jBPM Users] - [jbpm4] Move execution to arbitrary activity

by luca.tagliani

Hi all, I'm trying to move the execution of a processInstance to an arbitrary activity. I'm using the following code: org.jbpm.api.ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().processDefinitionName("processTest").uniqueResult(); | ExecutionService executionService = processEngine.getExecutionService(); | ProcessInstance instance = executionService.startProcessInstanceByKey("processTest"); | String newName = "Verified"; | Activity newActivity = ((ProcessDefinitionImpl) processDefinition).getActivity(newName); | ExecutionImpl execution = (ExecutionImpl) instance; | if (newActivity != null) { | ((ExecutionImpl) execution).setActivity(newActivity); | } but when I then signal the execution, the activity ran is not the one I've yet set, but the old one. I've also tried to use execution.moveTo(activity); but with the same result. It seems that the change is not persisted on the DB.... Is it a bug or am I making any mistake?

[jBPM Users] - jPDL decision or fork?

by cash1981

Hi. I am quite new to jBPM and wondering what I should in the following example. This is the snippet of the jpdl file: | <task-node name="review"> | <event type="node-enter"> | <action expression="#{attachmentHandler.setupAttachments}"></action> | <action expression="#{templateAttachmentHandler.setupTemplateAttachments}"></action> | </event> | | <task name="10-reviewInput" swimlane="handlingOfficer"></task> | <task name="20-reviewAttachment" swimlane="handlingOfficer"></task> | <task name="30-rulingAssessment" swimlane="handlingOfficer"></task> | | <transition name="next" to="permit"></transition> | </task-node> | | <task-node name="permit"> | <task name="40-ruling" swimlane="handlingOfficer"></task> | <task name="50-sendPermit" swimlane="handlingOfficer"></task> | <transition name="denied" to="denied"></transition> | <transition name="next" to="end"></transition> | </task-node> | In the task <task name="30-rulingAssessment" swimlane="handlingOfficer"></task> The user handlingOfficer has the option to do something. If he does A, I would like to design in JBPM "skip 40-ruling and go straight to 50-sendPermit", and if he choose option B in 30-rulingAssessment, I want to have the same behaviour as modeled. So my question is, how can I do this? Should I create a fork somehow from rulingAssessment or maybe just a decision node?

[jBPM Users] - Re: Deploy a project

by makarandk502

you can refer to ant build scripts ( building examples those are coming with jbpm ) for reference. That will give you some idea of deployment.
