Java install on Linux FC4 (Two very basic questions).

Hello:
This is very simple question... but the answer is not obvious to me!
I am trying to compile and run very simple "hello World" kid, java
programs.... and I am running into problems.

I am having errors messages, bnoth at compile (for some programs), and run
time.... and they are so far quite cryptic to me.

For info:
-------------
$1 rpm -qa java*
java-1_5_0-sun-1.5.0_01-5
java_cup-manual-0.10-0.k.1jpp_2fc
java_cup-javadoc-0.10-0.k.1jpp_2fc
java-1.4.2-gcj-compat-1.4.2.0-40jpp_31rh.FC4.1
java-1.4.2-gcj-compat-devel-1.4.2.0-40jpp_31rh.FC4.1
java_cup-0.10-0.k.1jpp_2fc
java-1.4.2-gcj-compat-src-1.4.2.0-40jpp_31rh.FC4.1
-------------

I have installed the Java run time engine as 1.5, but the rest is all 1.4,
this could explain some problems (not the compile): I imagine the byte code
generated by the compiler 1.4 is incompatible with the JRE (1.5)....

Q1: Where could I find the proper RPMS for FC4 Java 1.5 install ?
I (ave read thatSUN has problems).

Q2: Where could I find the list of Java compiler, and run time errors, and
how to interpret them?

Thanks.
