Hi all,

I have created two tables with a parent child relationship between them. The problem comes when i try to store parent and child objects together. I am getting exception the foreign key in child table cannot be null.

I want to ask how can i store parent and child objects together in a single session?

Also i have included cascade="save-update" in the relationship property in both of .hbm files. and i have tried save(), saveOrUpdate(), persist() metods. Also keep in mind i am using hibernate with spring. In that i am using Hibernate template.

you need to set the parent in the child, and set it up in your mapping file. Whatever foreign key columns are:

Code:

<many-to-one
        name="parent"
        class="..."

        not-null="true"
    >
        <column name="column1" />
    </many-to-one>


------------
child.setParent(parent)
