can someone explain what exactly is the

<index > element for.. when mapping a collection using the
<map element

I have been reading the docs and don't really get what its there for.

TIA,
Paul

Well, I'd say it could be used to define the index of a map, no?

then why is it required? if I already have a DB design done.. all the indexes are already there, then hibernate shouldn't really worry about creating an index even knowing if an index is there..

Quote:

For indexed collections like maps and lists, we require an <index> element. For lists, this column contains sequential integers numbered from zero.

can someone give me an example of what column they are talking about?

Thanks Christian and others

It's the index of a Java Map, not a database index.
