the bean attributes you want to be mapped to table attributes must be
public, that manner the container can 'reflect' the attributes.
(spec. section 9.4.1 Container-managed fields)
" The Bean Provider is responsible for using the cmp-field elements
of the deployment descriptor to
declare the instance�s fields that the Container must load and
store at the defined times. The fields must
be defined in the entity bean class as public, and must not be
defined as transient. "

I don't understand what you want, maybe using a SB to solve you
problem.
if you put a parameter in a EJBHome.create method, the deployment
descriptor will know about this, and the container is seeing the bean
through the deployment descriptor. ()

if you have 3 attributes on table A, and just want to map 2
attributes.
