Hi guys, it is just a question about relations in EJB.
in Order and LineItem example, the Order entity bean could have an ArrayList of LineItems(the two beans are BMP).
this ArrayList will contain the primary keys of lineitems.
or we can use a vector of stubs.
my question is:
which way is better for modeling relations between BMPs?
 
Consider Paul's rocket mass heater.
