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.
