Ok it is not very clear. Are you using CMP or BMP?
if you are using CMP then the remove operation is remove by primaryKey so
that is fairly straightforward and should only remove the records associated
with that primary key.
If you are using BMP (what is the delete on cascade thing?) then you will
have to explain what JDBC you do, but basically jboss will call ejbRemove()
once on your instance and it is up to you to do the proper work in the
database.
Let us know
