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 double userTelephone ;
private String userTitle = "";
private String firstName = "";
private String lastName = "";
private String userLocation = "";
private String userName = "" ;
private String userPassword = "";
private String userJobTitle = "" ;
private String userEmail = "" ;
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;

<class name="com.dss.ems.models.UserModel" table="DBUSER">
-
<id name="id" column="USERID">
<!--changed some time before from userId-->
<generator class="increment"/>
</id>
<property name="dateOfBirth" column="BIRTHDATE"/>
<property name="userTelephone" column="TELEPHONE"/>
<property name="userTitle" column="TITLE"/>
<property name="firstName" column="FIRSTNAME"/>

<property name="userPassword" column="USERPASSWORD"/>
<property name="userJobTitle" column="JOBTITLE"/>
<property name="userEmail" column="EMAIL"/>

<property name="isDeleted" column="ISDELETED"/>
<property name="addUserId" column="ADDUSERID"/>
<property name="addDate" column="ADDDATE"/>
<property name="editUserId" column="EDITUSERID"/>
<property name="editDate" column="EDITDATE"/></class>


<hibernate-mapping auto-import="true" default-lazy="false">
-
<class name="com.dss.ems.models.ExpenseModel" table="DBEXPENSE">
<!--attribues from AbstractEntityModel-->
-
<id name="id" column="EXPENSEID">
<generator class="increment"/>
</id>
<property name="isDeleted" column="ISDELETED"/>
<property name="addUserId" column="ADDUSERID"/>
<property name="addDate" column="ADDDATE"/>
<property name="editUserId" column="EDITUSERID"/>
<property name="editDate" column="EDITDATE"/><!-- attributes added in subclass-->
<property name="submittedAmount" column="SUBMITEDAMOUNT"/>
<property name="approvedAmount" column="APPROVEDAMOUNT"/>
<property name="rejectedAmount" column="REJECTEDAMOUNT"/>
<property name="expenseStatus" column="EXPENSESTATUS"/>
</class>


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

thanks in advance loking for your kind response

Unfortunately no. At the moment any mapping you define must have a single concrete storage location for each column.

I agree that it would be tremendously useful to have abstract or interface mappings. For example in my schema I have ICommentable, and ICalenderable interfaces on several of my business entities. Still I can just image how large the overhead would be to support it. So I can see why it isn't included.

You posted to a wrong forum, this is the NHibernate forum.
