Apple’s OS Lion has a pretty neat trick for handling the JAVA_HOME variable
Chill:bin rus$ /usr/libexec/java_home
which is super awesome as you can simply do
Chill:bin rus$ export JAVA_HOME=$(/usr/libexec/java_home)
Chill:bin rus$ echo $JAVA_HOME
to make sure you have the correct $JAVA_HOME set up, every time!
I’ve added this commend to my ~/.profile file so that whenever I open a new terminal, the $JAVA_HOME variable gets set correctly!
