JDK confusion

[Bob Hartung]

Hi all,
   I am going around in a circle re: jdk

   Initially I was trying to install a tomcat app calling for jdk1.4.2 
and tomcat4.  Once I get this installed manually and after removing 
every vestige of java that I could find on my FC4 install, I was 
notified that a new version of the app was now available that requires 
jdk1.5.0 and tomcat5.  Now what is the best way to install 1.5.0 and 
tomcat5 utilizing rpms or yum.

   I am not sure what packages I need.  I do see that sun has an rpm and 
that jpackage has a compat package..  but I am not exactly sure of what 
the compatability(?) package does for me. Or should I just get the 
tar.gz and install the jdk and tomcat5 manually?

Thanks,

Bob
