How do I Set JAVA_HOME on macOS X 10.6?

Setting JAVA_HOME on macOS X 10.6

In macOS X 10.6, the JAVA_HOME environment variable is essential for configuring applications that rely on Java. Existing paths for this variable include:

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

Recommended Approach

To ensure optimal performance and compatibility, it's advisable to set JAVA_HOME to the output of the following command:

/usr/libexec/java_home

This command retrieves the Java path specified in your Java preferences.

Customizing JAVA_HOME

Occasionally, you may need to use an earlier version of Java. For instance, if a program requires Java 5, you can set JAVA_HOME using:

export JAVA_HOME=$(/usr/libexec/java_home -v 1.5)

Adding java_home to Path

If java_home is not in your path, you can add it by running:

sudo ln -s /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java_home /usr/libexec/java_home
