Is there any way i cant create a custom finder that receives a Collection containing the primaryKeys i am looking for?
I'm not willing to write the entire code to make the custom finder.
You can with dynamic-ql in JBossCMP (JBoss 3.0 only). Download the JBossOne-JBossCMP slides at SourceForge for an example. BTW there is a typo in the slides it uses a declared-sql element instead of a dynamic-ql element. You'll see what I mean.
