I am up to the point of getting Java JDK1.4.2 installed.

I did a:        yum list|grep "java" and got:

gcc-java.i386                            3.4.4-2                installed      
java-1.4.2-gcj-compat.noarch             1.4.2.0-27jpp          installed      
db4-java.i386                            4.2.52-7.1             base           
gcc4-java.i386                           4.0.1-4.EL4.2          base           
java-1.4.2-gcj-compat-devel.noarch       1.4.2.0-27jpp          base           

Do I got what I need?

I tried:        yum install jdstk-1.4.2
and got nothing to install...

I don't see tomcat in my list of installed rpms.  Do I follow the instructions listed, or is there a yummy way to get it?  ;-)

Thanks!
