Ordering the children set in a parent/child relationship?

Hi, i'm pretty new to hibernate, so i'm sorry if i break any rules by posting this question.

I have implemented the a tree structure that is mapped from the database using the parent/child relationship, and it works great except the children set seems to populate in any given order and not always the same. Is there a way to apply order to the mapping of the children to the parents?

thanks

Perhaps you need to specify order-by="column_name asc|desc"

Hi,

I found that you were trying to map tree like structure by hibernation could you please have a look at my question?

shortly speaking it seems that mapping have a problem with highest node not having parent_id.

Do you have any solution for this.

Sincerely,
