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. Cheers Tony Grant -- www.tgds.net Library management software toolkit, redhat linux on Sony Vaio C1XD, Dreamweaver MX with Tomcat and PostgreSQL
