Using OnEntry and OnExit in JBPM 5 Human task

vigneshbhaskar Dec 27, 2011 3:17 PM

Please give me some examples on using OnEntry and OnExit action scripts in a Human Task in JBPM-5. When I write the action scripts on the node's property, it does not reflect in the bpmn2.0 XML. I understand that OnEntry and OnExit are not specifications of BPMN2.0, but if thats the case, how can we effectively use this feature on a Human task.

In my case, I want to send a notification email whenever the Human task is reached. I should be able to send a link to the process that task to the actor's email id.

Here is an example:
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-bpmn2/src/test/resources/BPMN2-OnEntryExitScriptProcess.bpmn2

And Demian's blog explain a little bit more about how to use this feature:

Thanks Mauricio for your reply, I followed the blog and added those onEntry and onExit entries in the bpmn xml. I was trying to retrieve the taskID from the workItemID using the following codes.

long workItemId = ((org.jbpm.workflow.instance.node.WorkItemNodeInstance)kcontext.getNodeInstance()).getWorkItem());
JBPMUtil.getTaskByWorkItemID(workItemId).getId();

I am able to retrieve the workItemId only on the onExit actionscript and not in the onEntry script. From the logger, i understand that the Task is created only after the onEntry script runs. I am still worried how i can send an email with the link pointing to the TaskID. Is there any alternative way of accomplishing this?

Hi Vignesh,

do you have a solution for that? I would like to send a notification in the onEntryAction with the taskId too. But actually I don't know how to get it.

WorkItemNodeInstance.getWorkItemId() returns -1, because the item isn't created in onEntryAction.
