after run the system i have an error as:
"Repated column in mapping for class Customer.Address should be mapped with insert="false" update="false": ID "

my mapping file for Contact.hbm.xml as:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="Customer.Contact, Customer" table="Contact">
<id name="Con_ID" column="ID" type="Int32">
<generator class="identity" />
</id>
<property name="Con_UID" column="UID" type="Guid" />
<property name="Con_Type" column="Type" type="Int32" />
<property name="Con_Contents" column="Contents" type="String(255)" />
<property name="Con_AddressID" column="ContactID" type="Int32" />
<many-to-one name="Con_Addresss" class="Customer.Address, Customer" />
</class>
</hibernate-mapping>

other mapping file which is connected with above was Address.hbm.xml as:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="Customer.Address, Customer" table="Address">
<id name="Add_ID" column="ID" type="Int32">
<generator class="identity"></generator>
</id>
<property name="Add_UID" column="UID" type="Guid" />
<property name="Add_Name" column="Name" type="String(50)" />
<property name="Add_Language" column="Language" type="String(50)" />

<property name="Add_City" column="City" type="String(50)" />
<property name="Add_Postcode" column="Postcode" type="String(20)" />
<property name="Add_State" column="State" type="String(50)" />
<property name="Add_Country" column="Country" type="String(20)" />
<property name="Add_CustID" column="CustID" type="Int32" />
<set name="Add_Contact" table="Contact" cascade="all">
<key column="ID"/>
<one-to-many class="Customer.Contact, Customer" />
</set>
<many-to-one name="Add_Customers" class="Customer.Customer, Customer" column="ID" />
</class>
</hibernate-mapping>

is there anything wrong with the mapping file,please help.....

I think it has got to do with the way you have mapped the many-to-one relation in the Address class.



Are you sure it is the column ID and not CustID (ID also seems to be the PK). If it has to be ID then add insert=false, update=false as the exception is suggesting.

You may find this related to the error you are getting:
http://forum.hibernate.org/viewtopic.php?t=952974&highlight=repeated

after i have added insert=false and update=false an error as:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Contact_Address". The conflict occurred in database "D:\NEW FOLDER\SIANG\CUSTOMER\CUSTOMERWEBSITE\APP_DATA\CUSTOMER.MDF", table "dbo.Address", column 'ID'.
The statement has been terminated.

the Address table:
ID->PK
CustID->FK for custamer table

the Contact table:
ID->PK
AddressID->FK for Address table

the Customer table:
ID->PK

means:
customer->Address->Contact

did i put in the correct column at the many-to-one statement?

Did you check the first comment I made....

I think it has got to do with the way you have mapped the many-to-one relation in the Address class.



Are you sure that the column in the above mapping is to be ID and not some other column as CustID.

thank i have solve it, i just need to add insert=false and update=false with column=CustID into Address.hbm.xml...
