Selecting Java Version on Mac OSX Leopard
I just downloaded the latest version of the wonderful, real-time SNMP monitoring application, asithappens. I'd had some problems getting the last few 0.5x versions to run properly but hadn't bothered to track down what was going on because the older version did what I needed. This morning a new feature, which allows you to monitor any OID, piqued my interest and I persisted.

With a hunt around my Mac, I found an application I'd never noticed before,
/Applications/Utilities/Java Preferences. Running it clearly shows that Leopard has both version 5 and 6 installed, but that version 5 was the default. To change all I had to do was go to the "General" tab, then under the "Java application versions" section drag "J2SE 5.0" below "Java SE 6".
Nice! I like it when there are simple solutions. Thanks to Mark for writing awesome software and supporting to so graciously. Thanks to Apple for making this so easy.
