I can confirm that that inserting dates via JSP + the JDBC driver into
Postgresql does exactly this.

If you want a nice interface that inserts dates in the DD-MM-YYYY format
you will have to write a nice little Javascript function that puts the
date back into the right order before inserting into the database.

SELECT to_char(dateexpofin, 'DD-MM-YYYY') as end, dateexpofin
ORDER BY dateexpofin DESC

will write out the date in "normal" European order and put the latest
date on top of the list.

I was stuck on dates a while back.
