I did a Google search on "tomcat netbeans postgresql tutorial" and turned up some likely-looking links.... should work for you too. :-) Ray. -- Raymond O'Donnell :: Galway :: Ireland rod@iol.ie

I already had lots of trouble with customers asking me to adjust my systems to this new "situation", then I've to change systems and database... Regards, Edson Richter

Agreed, that thread had me diving back into my biology textbooks. Turns out they only partially covered the topic. > > Ray. > > -- Adrian Klaver adrian.klaver@gmail.com

If you are looking at biological/physiological attributes (chromosomes, hormones, testicular-cancer, ...), use "sex." If you are tracking social attributes or characteristics (preferred dress-style, sexual-preference, income, prevalence in various professional roles, etc.), use "gender." See http://www.who.int/gender/whatisgender/en/ Either way, an expandable lookup-table may end up being useful. Just when you think you are strictly dealing with "sex" and you hard-code for "male" and "female", someone will show up and ask you to rewrite your code to account for chimeras (http://en.wikipedia.org/wiki/Chimera_%28genetics%29).
