Which means that when you are accessing the entity manager in your createAirport method, there should be an active transaction. As you already correctly mentioned:

I believe when the createAirport method is being called, there is no active transaction and since the transaction attribute that you have specified is SUPPORTS, the server wont create a new one. You might want to change the transaction attribute to REQUIRED instead of SUPPORTS. For transaction attribute REQUIRED, a new transaction is created when there is no active transaction. If there is a active transaction then the same will be used for that method. So try changing

to 

@TransactionAttribute(TransactionAttributeType.REQUIRED)
