Hello,

I have a 1:n association between 2 tables, A and B.

How can I generate a unidirectional Hibernate mapping between them?

This is, I want class B to have a reference to class A, but it shall not be possible to navigate from A to B.

Is this possible?

cheers
Stefan

stefan,

To do this, you need to create a custom reveng.xml file in your project. Here is an example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>
    <table name="A" schema="SCHEMANAME">
        <foreign-key constraint-name="FOREIGNKEYNAME">
            <set exclude="true" />
        </foreign-key>
    </table>
</hibernate-reverse-engineering>

Please replace SCHEMANAME/FOREIGNKEYNAME with appropriate names corresponding to your tables. If you already have a hibernate.reveng.xml file, please merge the contents above with your existing file. If your existing file already has a <table> element referencing table A, you will need to add the <foreign-key> section to it.

On page 2 of the RE wizard, point the rev-eng settings file field to this file and click Finish.

Hope this helps.
