Hi, I am building an application and have used JDO for datastore for implementing use cases. Now when I am implementing the backend machine which is a bit complex in relationships among objects then I am facing hard times with JDO (May be due to lack of my knowledge). I have following questions to ask,
1. Can I use reference of objects in more than one classes? For example, Class A is persistent and being used as foreign key in Class B and Class C. Do I need to create unowned relationships through Key or can I use some annotation (or something) to mark a field of type A as foreign key? When I make a field of type A in class B, and assign an object of class A to it, it is stored as new object as child of B :s 2. Can I use objectify for this use case only (mixing with jdo) and will it simplify stuff or not, any experience comment? Thanks in advance. regards Ijaz -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
