Extending timers or creating custom jobs

sravyts Oct 29, 2009 5:02 AM

We are looking into implementing the following BPM construct in jbpm:

start -> task 1 (inputs an activity date) -> wait for the first working day after the activity -> task 2 -> end

Is there a way we can implement this? I was looking into using a wait state with an event listeren on "start" which would create a job, with the calculated duedate, and when the job is executed, the execution is signalled so the process continues.

But I can't find a way to create custom jobs? There doesn't seem to be an api to create jobs? Is this something that will be available in the future?

Wkr,
Sofie

Hello sravyts!

So basically you want to put a timer on a transition but you do not want to set the duedate in the process definition but during runtime, right?

AFAIK there is no API to create jobs. ManagementService just exposes a method to execute jobs and to search for jobs by creating a JobQuery. If this is really the case I would consider you to fill a JIRA issue and to propose the extension of the API.

All jBPM object are in fact Hibernate objects. So you can simply programmatically create a Job with the correct date and save it through the hibernate session.

Best approach to this is to write a custom Command and invoke it through the CommandService (there are plenty such examples in the source code).
