Need Easy Way to install & configure Java JDK & Tomcat on Fedora 13/Linux

I am trying to install Java JDK & Tomcat on my Fedora 13, however I am
facing lots of issues.
I have gone through many blogs and many Stack Overflow posts, but still I
am unable to configure it properly.
Info:
I am trying to install JAVA JDK using .rpm package as I am unable to do it
using YUM repository. (You can also tell me how can i install yum
repository).
I tried to install the JDK & tomcat but after installation, when I tried
to start tomcat using startup.sh, it was giving error like:
Using CATLINA_HOME
Using CATLINA_BASE etc etc
How to find JDK path & configure JAVA_HOME path.
I know my questions are really confusing, but I need help. Links to posts
of related questions would be appreciated as well.
