Try out these Guides:

My Guides - http://www.my-guides.net/en/content/view/91/26/

Unofficial Guide to Fedora - http://www.fedoraguide.info/index.php/Main_Page

I would also suggest using the Livna Repository to get your packages and yumex to manage them
you can get this by typing the following code into terminal as root

Code:

su -

rpm -hiv http://rpm.livna.org/livna-release-8.rpm
rpm --import http://rpm.livna.org/RPM-LIVNA-GPG-KEY

yum install yumex

Hope these guides help you out..

04 Oct 2008 22:12 how to run java in fedora

There is no real java in Fedora, Only gcj compatible compiler (The Fedora devs. even rebuild eclipse with gcj so it's a native and not a portable app). Go to sun.com and download the java runtime and java development packages, if U use eclipse get it from the eclipse home page.
If U want to build fedora apps with the java language use gcj (GNU Compiler Java)
