How to get JBPM variable Taskinstance id ?

[parimal.parimal.chauhan.criti.in]

Hi,
While using JBPM, JBPM variables like taskinstanceid,processinstanceid are stored into JBPM tables.In my application I need store few of them into one of my table too.Creating process and tasks is taken care by annotations so how can we get access to these variables ?

@Observe the events raised during the processing of that annotations: org.jboss.seam.initProcess.<process-name>, org.jboss.seam.startTask.<task-name>, etc

Hi,
Thanks for quick reply.This is really helpful.
is there any API that we can use to get taskinstanceid or other JBPM variables with this annotations.

thanks in advance.

Yes, there are.

Either let Seam to inject the TaskInstance (@In TaskInstance taskInstance) or use org.jboss.seam.bpm.TaskInstance.instance()) in order to get the org.jbpm.taskmgmt.exe.TaskInstance.

Then, of course, taskInstance.getId() will give you the taskInstanceId.

The same apply for BusinessProcess.

@In TaskInstance taskInstance;

@Observe("org.jboss.seam.startTask.mytask")
public void taskStarted()
{

   log.debug("The task mytask with id = {0} was started.", taskInstance.getId());

}
