Hi
Sorry, I write this message for the second time, because I can't find the first.
I have following relationship :
project 1 --> participant 1 --> * services (uni)
Now I need a list about one special service with the names of the participants.
What's the best way to do this.
1. EJBQL with IN ...
or 2. define a bidirectional relationship
project 1 --> * services * --> 1 participant and use the CMR Collections ?
Is it a performance problem to have a lot of relations ??
E.g. my project is a central bean. Should I kepp the relationships down ?
