<p>My program works already, I have Perl (GUI Window) where I can input data, data passed to the webpage (using to Tomcat server, JSP) and then <strong>saved</strong> it to oracle database. What I want is to make search parameter (webapp) that <strong>retrieve/extract</strong> data from the Oracle database using Perl CGI. Is it possible? Or any suggestions to solve my program? Thanks!:-)</p>

Any specific reason for the mix in technologies? Why not use a servlet/JSP?
If you must use Perl, then you need to choose what web-server will run your Perl script.
Normally, this would be Apache using
mod_perl
.
But if you only intend to use this for a few admin scripts, then you can run Perl from tomcat as outlined
here
.
Once you have managed to get a simple perl script running, then I would look into using
DBI/DBD::Oracle
to access your database?
Hope this helps...
