[CentOS] Firefox and Java on CentOS 4.1

I need to run a Java-enabled Firefox on my CentOS4.1-powered laptop and it
*was* running fine.  Then yesterday I up2date'd the box and Firefox went
from 1.0.4 to 1.0.6.  And I lost Java.  

I can't seem to re-install it, whether from the original (1.5.0 I think it
was) or the latest downloads.

This is crucially important as I need to access my Dell RAC.  

Can anyone advise how to get Java back.  At the moment, I have had to
reboot my laptop into Redmond-ware :-(((

TIA

John
