How to set the JAVA_HOME variable in Mac OS X – Snow Leopard

Recently I had to setup a Java app on my Mac, which was running from the Terminal, and needed the JAVA_HOME variable set.

Here’s what had to be done:

- Start the Terminal app.
- Create/Edit ~/.bash_profile file.
Note: I first tried creating and using the ~/.bashrc file, but that didn’t work (Mac OS 10.6.2), while ~/.bash_profile worked as expected.

Therefore,

$ vi ~/.bash_profile

… and paste the following (make it a single line):

export JAVA_HOME=/System/Library/Frameworks/
JavaVM.framework/Versions/CurrentJDK/Home

… save and exit vi.

Restart Terminal app just to be sure that it worked, and try accessing it by typing:

$ echo $JAVA_HOME

If you see the correct JAVA path, then it is all done!

我的电脑显示如下:

macbookpro:bin shang$ echo $JAVA_HOME

/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
