Setting JAVA_HOME on OSX lion

I recently upgraded to OSX 10.6.8 (Lion) and found that my JAVA_HOME was no longer set correctly. I found this out when my command line ec2 tools failed.

If you currently have your JAVA_HOME set to something like “/Library/Java/Home”,
under OSX Lion, you’ll want to change that to $(/usr/libexec/java_home), thus:

export JAVA_HOME=$(/usr/libexec/java_home)

The script /usr/libexec/java_home outputs the true location of JAVA_HOME, so unless that script goes away, this should prove upgrade safe.
