Do like this:
/**
* @ejb.relation
* name="empleyee-address"
* role-name="employeeHasAddress"
* cascade-delete="yes"
* target-ejb="EmployeeAddress"
* target-role-name="addrBelongEmp"
* @jboss.relation
* fk-constraint="true"
* related-pk-field="employeeID"
* fk-column="eid"
*/
public abstract EmployeeAddress getAddress();
If not work, let me know.
