First day == help

[Hussein Baghdadi]

Hey ranchers.
this is first day with jboss so please be patient this week !
I have two entity beans : DeptBean and EmployeeBean
this is the database schema for these 2 bean :
DeptBean :
ID, DESCRIPTION // ID is PK
id, description // ejb-jar.xml
EmployeeBean:
NUM, NAME, ID // NUM is PK & ID is the PK of DeptBean
num, name, id // ejb-jar.xml
of course the relationship is one-many.
I don't know how to set this relation at jboss-jdbc.xml , so would mind posting just the relationships element that compatibile with my 2 bean ??
its not clear to me, as I know I should mix the name of the fields with
their equivalents in ejb-jar.xml to produce relationships element.
thanks.
