Please let me preface this by saying that I am not the biggest linux expert. I have a teaming and conferencing server that has been running for several months now. When I tried to upgrade it to SP2 I got the following error:

JAVA_HOME is set to: /usr/java/jdk-1_5_0_12
Installer exiting: JAVA_HOME is not pointing to a JDK installation.

It has been a while since I installed this server but it seems to me that this is the proper information. Any Advice?
