Yes,
The confusion occurs because ejbCreate() means different things wrt Entity
or Session beans.
home.create() on a session bean is saying "Ok, I want to use a session bean
now"
home.create() on an entity bean means "I want an entry put into the
persistant store"
and of cos for remove:
session: Ok, I am done
entity: nuke that bad boy from the store
It may have been better to have the different interfaces have different
method names.
