I have mapped them succesfully, and created a helper class Beta_PK which I use to persist table Beta.
These tables have unidirectional 1:n relationships, better said Alfa-contains-many-Betas. I'd like to be able to do
However I can't map the relationship if my life depended on it.
Can somebody please tell me how do ejb-jar.xml and the rest of DDs look like (I use Weblogic 8.1)? Basically it's the compound key which is at the same time the primary key to Alfa which gives me trouble.
