Netbeans 6.1 - Add Server Instance (tomcat 5) on Fedora 10

[fhaider]

Hello.
I am trying to add a tomcat 5.0 server to a project with Netbeans 6.1 under Fedora 10. On the Netbeans IDE 6.1 menu I click on "Tools", "Servers", "Add Server", I select "Tomcat 5.0" from a list, then click the "Next" button and a window "Add Server Instance" and it asks me to "Specify the installation folder (Catalina Home) ...". I can't find where tomcat in installed in my machine.
Could anyone please help me resolving this problem?
I am attaching an image "netbeans_add_server.jpg" of the "Add Server Instance" window I get.
Thanks
Farid
