>From the EJB 2.1 spec, 10.5.7:
'An ejbSelect<METHOD> is not based on the identity of the entity bean
instance on which it is invoked. However, the Bean Provider can use the
primary key of an entity bean as an argument to an ejbSelect<METHOD> to
define a query that is logically scoped to a particular entity bean
instance.'
So, for the finder you could do the same thing.

Subject: Re: select methods: special case?
Hi,
I guess I could do that indeed, but I was just curious as to whether it
is possible to focus on just one instance with ejbSelect, and how...
Thanks,
Hans
