Get Action from Timer. Earlies execution time

[jjrs]

Hello,

In my process definition we have several nodes (containing actions), that have to have an "earliest start time" associated to them. The best way I found for implementing this functionality was creating a State node, create a timer inside it , and associate the action to the timer. Something like the example below:

<state name="LoadConvertedCont1" async="true">
 <timer duedate='#{executionStartTime + 1 Hour}' >
 <action class="com.xxxxx.jbpm.actions.Adaptor" async="true" name="loadConvertedContributions">
 <taskBeanId>
 loadConvertedContributions
 </taskBeanId>
 <maxDurationMinutes>
 60
 </maxDurationMinutes>
 </action>
 </timer>
 <transition to="LoadConvertedCon2"></transition>
 </state>

Everything is fine, until I try to stop the execution of the action. I have my own implementation of the JobExecutorThread. I extended the API for being to interrupt the execution of an the action. If the action was inside a node of type node, the code for accessing it, is quite easy :

Action action = job.getToken().getNode().getAction();

But when the action is inside a timer and the timer is inside a Node of type State, I don't see an easy way of retrieving the action object, and the only possible way that I have found is using the HibernateProxy provided by Hibernate, although I don't consider this is the best option

Timer timer = (Timer)((HibernateProxy)job).getHibernateLazyInitializer().getImplementation();
Action action = timer.getAction();

Is there any way, using the JBPM API for retrieving the action being executed from the JobExecutorThread ?

job.getToken().getNode().getName();
//is providing me the correct name of the Node (even if it is if type State)

runningJob.getToken().getNode().getAction();
//is null when the action is inside the timer, and the timer inside the State Node.

Regards.
Jose.

I'm no expert in this area, but why do you state

although I don't consider this is the best option

If jBPM implemented this in the api, it would probably be implemented like you do with a hibernate proxy.

Hi Ronald,

Thanks a lot for your answer (I was not "watching" this topic so I missed your answer).

My knowledge of hibernate is quite limited, however I thought that there might be a cleaner way of getting the timer and the action. Being honest I didn't check how the information of the other entities (tokens, nodes, etc.) are retrieved from the DB and transformed into objects.

I will have a look to it.

Thanks.
