uh but that is a common pattern i would think. loading n rows from the
db via ejbFindByXXX results in at least n+1 queries to the DB (1 to
find the primary keys, n to instantiate the beans). this is clearly
inferior to using a single query and putting the resultset into DAO's
or whatever you might call them.
