# There is a fantastic, well-supported, simple solution for Mac OS X Leopard developers to install Java SDK (”JDK”) called SoyLatte.  So far, this is the simplest way I’ve found to install Java on Mac, and it’s based on all free and open source Java (and soon to be a part of OpenJDK, the open source Java developers’ initiative).

# Note: Java SDK (”JDK”) comes pre-installed on Mac Leopard.  Sometimes you want to have more control over your Java runtime installation, and un-installation, if the occasion calls.  Check out Apple’s site for more info on the pre-installed version of Java: http://developer.apple.com/referencelibrary/GettingStarted/GS_Java/index.html

### INSTALL JAVA ON MAC ###

1. Download SoyLatte archive file to any place you want on your Mac: 
soylatte16-i386-1.0.3.tar.bz2

wget http://hg.bikemonkey.org/archive/javasrc_1_6_jrl_darwin/soylatte16-i386-1.0.3.tar.bz2

2. Unarchive SoyLatte.

tar -xvf  soylatte16-i386-1.0.3.tar.bz2

3. Set environment variable for $JAVA_HOME to point to the SoyLatte directory.

nano ~/.bashrc
export JAVA_HOME=/Users/me/src/soylatte16-i386-1.0.3
export PATH=$JAVA_HOME/bin:$PATH

4. Save bash profile and refresh it to set the source environment variables.

source ~/.bash_profile

5. Check that Java is installed correctly.

which java
java -version

DONE!
