update jdk jre for bi platform 4.1
we are looking into updaing the jre/jdk for bi platform 4.1 (windows 2008 server)
I found note: 1183469 on how to do this but the information seems outdated.
is it recomended to update just the JRE, both JDK/JRE or neither?
Is this something that should only be updated via upgrades to the platform?
any help is appreciated.
