Charset problem with mysql

Hi, i'm sorry to post another question on charset problem but i'm
going out crazy
I'm working with Mysql 4.1.20, Apache2 and jsp pages.
I've a jsp page that shows query results so no one letter in this
page
is written by me. All mysql tables are encoded with latin1 charset
and
latin1_swedish_c1 collation. In http.conf i've added
"AddDefaultCharset ISO-8859-1" directive.
But i've no idea why accented words are replaced by a simple "?".
I've
added <META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset=iso-8859-1"> in my jsp pages but nothing at all

And besides if i do a query in mysql all result are exactly showed
and
if i write something like this "àèò" in jsp page, in browsers all
goes
ok


Thank u all
