How to upgrade Java from 1.5 to 1.6 on Mac OS X 10.4+

This is really simple.
Run the following command

Step 1: rm /usr/bin/java (if you are concerned, make a copy to backup)

Step 2:
"sudo ln -s /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Commands/java /usr/bin/java"

Before upgrade:
"java -version"
java version "1.5.0_19"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_19-b02-304)
Java HotSpot(TM) Client VM (build 1.5.0_19-137, mixed mode, sharing)

After upgrade:
"java -version"
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03-211)
Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02-83, mixed mode)
