"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.
