Hi,

I have big problems with understanding the one-to-many relation.

For example, if a parent has 3 childeren:

Parent 1
|- child 1
|- child 2
|- child 3

I have the following java code.

Collection childeren = parent.getChilderen(); // works fine….

But how I remove child 3, and change the age of child 1

Also how can I sort them age, then on name (order by age, name)...

Thx in adv.
Pieter

These are all basic questions, which are covered in the documentation and the Hibernate in Action book. Please read the documentation.
