Uninstall Oracle Java 7

Uninstalling the JRE

To uninstall the JRE, you must have Administrator privileges and execute the remove commands either as root or by using the sudo(8) tool.

Remove one directory and one file (a symlink), as follows:

• Navigate to /Library/Internet Plug-Ins and remove the JavaAppletPlugin.plugin directory.
• Navigate to /Library/PreferencePanes and remove JavaControlPanel.prefpane.

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
