Title: how to displaying "<" in browser

Hi friends,

I am using "&lt" and "&quot' to display "<" and double quote (") respectively. Everything is fine in IE4 but not in netscape.  Can anyone give me some tips.  Plus, how can my server side servlet/jsp detect what browser the clients are using?

Any helps are highly appreciated
