I posted the question as to find out what the standard approach is to achieving database persistence; I wouldn't post the question if i had already decided which way i was going. Hmm. Maybe I should capitalise subtle hints in the future ;) Thanks to the people that suggested iBatis and Hibernate - both look very interesting and will read up on them. Both seem to have a good following on this list.

Re: [OT] persistent data storage - the right way
Java object inspector:
http://www.programmers-friend.org/JOI/
When you dbl-click on a result in hibern8ide it pops up a JOI window and
you can check the values of every attribute in the object - very useful
indeed!

Re: R: persistent data storage - the right way
Leonardo,
You're correct. Unless you want to do specific queries on the database the
hibernate layer takes care of all queries to the database.
If you do have to do clever stuff, be sure to download hibern8ide it is
very good for perfecting queries, and very powerful when combined with
JOI.

I think that with hibernate you don't need to write sql
code to save/update/delete your objects or to retrieve
objects by their id, with ibatis you have to write
all your sql code.
Example with hibernate (pseudo-code...):
session.find(MyObject, id);
MyObject.setProp1(newvalue)
session.save() // automatically execute an update on your db
You don't have to write a line of sql with hibernate...
(except for queries like "select from MyObject where age>23")
Anyway I'm not a Guru, so I could be wrong...

I think that with hibernate you don't need to write sql code to save/update/delete your objects or to retrieve objects by their id, with ibatis you have to write all your sql code.

Re: persistent data storage - the right way
One advantage hibernate has over ibatis is xdoclet support. You can generate your mapping files from xdoclet comments which means that you have the mappings and java code in the same place. Perhaps there's ibatisdoclet but I haven't noticed it. Other advantages vs disadvantages I haven't a clue about as I've never used ibatis.
