This is something that bothers me. There is nothing in the EJB spec
which requires N+1 queries (at least not for CMP beans), and it seems
like an order-of-magnitude performance gain could be obtained by
providing a server-specific "get data in one query" option for finder
methods.
Are there any app servers which support this feature?
