Hello,
I have two types of persistent objects in my application : objects that are
stored in a RDB and objects that are managed from an other application (for
instance, in my environment persons and adresses are managed in a legacy
application developed in Natural/Adabas). The objects of the second type
are considered as read-only, I don'need to store them back after the
processing. The objects of both types are mixed in the business model, the
business layer of the application does not need to bother where the data is
stored.
Example : I have a class Car with has an Owner. Car is stored in my RDB and
the table contains the identifier of the owner. Owner is stored in the
external application. When OJB instantiates aCar it should also instantiate
it's Owner.
I tried with the factory-class, but since the factory-method does not
accept parameters, I don't know how to pass the identifier of the owner and
I need that information to call the external application's API. Is there a
way to get access to the db-row from the factory-method ? If no, is there a
smarter way to do the job ?
Thank you for the help
Stefano
