Problem in a composite primary key

Hi,

I understand your question as follows. You have 3 entity beans eb1, eb2 and eb3. You have primary key pk1 for eb1 and primary key pk2 for eb2. These two keys are part of eb3, and together they should be the primary key for eb3.

What I always do in those cases is to add an additional field to eb3 and concatenate pk1 and pk2. This is specifically easy when pk1 and pk2 are Strings. Perhaps this is not the best way, but I find it very useful, as it is very easy when your primary key is stored in only one field.

Hope this helps, Sponiza
