Hi all,

I would like to implement a tree structure for different layers of categories
E.g

Trades -> electrical, plumbing, handyman…
|
|->parttime, fulltime, experienced, non-experienced

public class Category {
private ArrayList<Category> subs;
private String description;

public Category(){}

public Category(String _desc)
{
description = _desc;
}

public void setList(Arraylist<Category> arylst)
{
….
}
public Arraylist<Category> getList()
{
return subs;
}
}

transaction = session.beginTransaction();
session.save(categoryhead);
transaction.commit();

The data structure is a multilayer tree. How can this be implemented by hibernate?
Thanks
