Hi again,
It should be working. But it isn't working in my case :). I am sending my
hibernating mapping with this email.
The scenario is I have Author Bean which has one property type as Set which
holds Collection of the Title Bean. And in Title Bean I have property type
Set which holds collection of Authors.
I have this Author which has collection of five Title I need to add it to
database.
session.save(author). Only Author gets saved not the Title. If you have any
example or any site which explains this please let me know
thanks
regards
prasad chandrasekaran
<hibernate-mapping>
<class name="presci.walnut.manytomany.Author" table="author">
<id name="id">
<generator class="identity"/>
</id>
<property name="name"/>
<set name="work" table="author_work" inverse="true">
<key column="author_id"/>
<many-to-many class="presci.walnut.manytomany.Work"
column="work_id"/>
</set>
