JAVA_HOME on Mac OS X

I was working on configuring HBase to run on my Mac OS X machine, and I ran into a hiccup setting up the JAVA_HOME environment variable. Eventually, I determined that there’s a “Home” directory inside of each Java Framework. So, the full command is is:

export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home

Globetrotter Connect for Option PCI Express card and Mac OS X 10.5.7

Edit: I may have jumped the gun. After a few more days of use, it seems like the Globetrotter Connect software is no more buggy than it was before the 10.5.7 update. The multiple kernel panics must have been a coincidence.

Warning! I installed the Mac OS X 10.5.7 update this past weekend, and I’ve had a lot of problems today with the Globetrotter Connect software. It has caused 2 kernel panics in under an hour of use . If you use this software, I’d strongly suggest waiting for a new version before upgrading to Mac OS X 10.5.7.

In a few days, I’ll give an update on if the KPs continue, or if it’s a transient error.

Here’s the lovely KP back trace that I’ve seen a numer of times:
