Hi Russ,

Firstly thank you for your reply, but I am obviously missing something. 
Yes the sun rpm installs and builds fine. But I have just tried with 
java-1.4.2-gcj-compat as you recommend and no change. So the 
alternatives is not configured as I expected

So under


      E. Sun JDK 1.6

Up to

chmod +x jdk-6u7-linux-x64-rpm.bin
./jdk-6u7-linux-x64-rpm.bin

Works as expected

But I couldn't work at what I should be using as an alternative to this line 
rpm -Uvh jdk-6u1-linux-i586.rpm java-1.6.0-sun-compat-1.6.0.01-1jpp.i586.rpm
as no appropriate java-1.6.0-sun-compat exists

So I just did  
rpm -Uvh jdk-6u7-linux-amd64.rpm

This left me in a situation where no Java related stuff is installed in alternatives.

so I did 
rm /usr/bin/java
/usr/sbin/alternatives --install /usr/bin/java java /usr/java/default/bin/java 1
rm /usr/bin/javac
/usr/sbin/alternatives --install /usr/bin/javac javac /usr/java/default/bin/javac 1

I then went and downloaded the jdk-1_5_0_15-linux-amd64.bin and 
installed that doing the similar process with alternatives.

After I read your e-mail I did a yum install java-1.4.2-gcj-compat

This has left me with the following setup as far as alternatives is 
concerned

+ 1 /usr/java/default/bin/java
2 /opt/jdk1.5.0_15/bin/java
* 3 /usr/lib/jvm/jre-1.4.2-gcj/bin/java

Is this likely to be fine or most likely gonig to cause me issues in the 
future ?

Anyway thank you for any incite you or others may offer.

Have a nice day :)
