What should I set JAVA_HOME environment variable on macOS X 10.6?

Many Java applications that use shell scripts to configure their environment use the JAVA_HOME environment variable to start the correct version of Java, locate JRE JARs, and so on.

In macOS X 10.6, the following paths seem to be valid for this variable

/Library/Java/Home
/System/Library/Frameworks/JavaVM.framework/Home
/System/Library/Frameworks/JavaVM.framework/Versions/Current

Some of these are symlinks to the actual current VM (as defined in the Java Preference pane).

But which one should be used—or is it okay to use any of them?

Also, it`s interesting to set your PATH to reflect the JDK. After adding JAVA_HOME (which can be done with the example cited by 'mipadi'):

export JAVA_HOME=$(/usr/libexec/java_home)

Add also in ~/.profile:

export PATH=${JAVA_HOME}/bin:$PATH

P.S.: For OSX, I generally use .profile in the HOME dir instead of .bashrc

It is recommended to check default terminal shell before set JAVA_HOME environment variable, via following commands:

$ echo $SHELL
/bin/bash

If your default terminal is /bin/bash (Bash), then you should use @hygull method

If your default terminal is /bin/zsh (Z Shell), then you should set these environment variable in ~/.zshenv file with following contents:

export JAVA_HOME="$(/usr/libexec/java_home)"

Similarly, any other terminal type not mentioned above, you should set environment variable in its respective terminal env file.

This method tested working in macOS Mojave Version 10.14.6.
