error in delegate java service task when using timer

idr_mdi

Hello,
i'm developing a java application, with spring and activiti intedgred in it.
the application is jpa and hibernate based for dataAccess.
here is my issue:
my activiti process is simple:
start event –> service task –> end event

when calling the dataAccessManager to insert feature in database during a service task java delegate i have no probleme. but when i change my process into this:

star event–> timer intermediate catch event –> service task –> end event
the timer just wait 10 second before calling de service taks, in this case i have this exception throwed:

ERROR: org.activiti.engine.impl.asyncexecutor.ExecuteAsyncRunnable - Job 97517 failed

the java delegate code : error is thrown in the save method

public class TEST implements JavaDelegate {
   
   @Override
   public void execute(DelegateExecution execution) throws Exception {
      // TODO Auto-generated method stub
            ITicketManager tm=(ITicketManager) execution.getVariable("ticketManager");
               Ticket ticket=new Ticket()
      tm.save(ticket);
   }
}

some infos:
i have tried to change the timer to async and various options of activating the jobExecutor and the syncExecutor, always the same issue.
the dataaccessmanager is @transactional annotated.
activiti version : 5.18.0
thanks guys for the help

"the dataaccessmanager is @transactional annotated."
that means you have @Transactional annotation in ITicketManager? (if so, is it an interface, or a class?)
if you have @Transactional on the interface maybe is better to move it in the concrete class.

Would be nice if you could provide a unit test for it and then the community could investigate directly on your code (which is easier and productive than trying to reproduce it first)

Hi vasile,

thanks for your reply.

ITicketManager is an interface, the implementation Class (TicketManager) is @Transactional annotated.
whene i execute the service java delegate as non asynchronous task , it executes. i can have the TicketManager instance from the line code
<code>
ITicketManager tm=(ITicketManager) execution.getVariable("ticketManager");
</code>

when i change the task to be asynchronous the same line code retrun a "com.sun.jdi.InvocationException occurred invoking method."

remark:
when calling other beans (not DataAccessBeans) , i have no problem the get the correct instance.

thanks

Hey,

i found a solution for my problem.

i don't pass the TicketManager as a variable during the process start but i inject it in the task via @Autowire (having the issue of null but solved it by setting the java delegate tas as spring bean).

thanks.
