Thank you all for your help.
For now, the problem is solved.
Recap:
If anyone have apache running on a machine, and glassfish up and running on localhost, a minimal solution to make jsp available on net is to setup the virtualhost for the domain like this:
<VirtualHost *:80>
ServerName www.domainName.tld
ServerAlias domainName.tld
RewriteEngine on
RewriteRule ^/(.*)
http://localhost:8080/$1 [P,L]
</VirtualHost>
Thank you,
virgil
