Falko thank you for your reply...
but the thing is I didn't install the connecter yet between apache and tomcat.
so i'm trying to access the servlet directly through tomcat server on port 8080
and I got an error 404 page not found .. redirect problem ..since my actual
folder is found under this folder on /home/userX/webapps/WEB_INF/classes/HelloWorld.class
I've read a lot of article and i'm still havin the same problem ...
thank you in advance
