hibernate 3

oracle 9i data base


problem is as follows

public abstract class AbstractEntity
private Long addUserId = null;
private Date addDate = null;
private Long editUserId = null;
private Date editDate = null;


public class UserModel extends AbstractEntity {
private Long userId ;
private Date dateOfBirth = null ;

private int userSex ;
private int userMaritalStatus ;
private String userAddress = "" ;
private String userAddressType = "" ;
private Date dateOfJoining = null ;
private int isProjectManager ;
private int isDeleted;


public class ExpenseModel extends AbstractEntity {
//private Long expenseId=null;
private double submittedAmount=0.00;
private double approvedAmount=0.00;
private double rejectedAmount=0.00;
private int expenseStatus=0;

[color=cyan]in this case while defining mapping files for UserModel and ExpenseModel
i have to do mapping for AbstractEntity in both mapping files (mapping parameters from abstract class) is there is any way by which i can define variables from superclass at one place and later on reuse it in defining my subclass mapping files [/color]thanks in advance loking for your kind response
