System Requirements

  • Any Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
  • Administrator privileges.

Note that installing the JDK on a Mac is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.

Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version.

JDK 7 Installation Instructions

Installation of the 64-bit JDK on Mac Platforms

When you download the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

After the software is installed, delete the dmg file if you want to save disk space.

Determining the Default Version of the JDK

A: If you have not yet installed Apple's Java Mac OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See Note for Users of Macs that Include Apple Java 6 Plug-in.

There can be multiple JDKs installed on a system – as many as you wish.

When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 7u6, you will see a string that includes the text 1.7.0_06. For example:

To run a different version of Java, either specify the full path, or use the java_home tool:

For more information, see the java_home(1) man page.

Uninstalling the JDK

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

Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*

For example, to uninstall 7u6:

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.

*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.

Why Do I Need Java to Use Apache OpenOffice?

Java is required for complete OpenOffice functionality. Java is mainly required for the HSQLDBdatabase engine (used by our database product Base) and to make use of accessibility and assistive technologies.Furthermore some wizards rely on Java technology. See additional topics pertaining to the use of Java in OpenOfficeand Apache OpenOffice in theInstallation FAQ.

So what does this mean exactly? Base (the database component) relies completely on Java technologies to run, but otherprograms (like Writer, Calc and Impress) only need Java for special functionality. If you do not need to use Base and donot want to use any of the Wizards, then you do not need to have Java installed and configured for running ApacheOpenOffice (and older versions of OpenOffice.org). You can completely prevent OpenOffice from prompting you about the useof Java by telling OpenOffice not to use a Java runtime environment (JRE). From the OpenOffice main menu use:'Tools - Options... - Java', and uncheck 'Use a Java runtime environment'. However, we do recommendthat you have a JRE on your system to take full advantage of OpenOffice's features without any issues.

Legacy versions of OpenOffice.org 3.3.0 and older included a JRE packaged with the download. Apache OpenOffice3.4.0 and newer do not!

Which Java Version Do I Need to Use Apache OpenOffice?

Java Mac Os

You will need to have a JRE version (32-bit or 64-bit) that is compatible with the architecture of the ApacheOpenOffice version you downloaded. If you already have a JRE installed on your system that satisfies this requirement inone of the standard areas for Java installation, OpenOffice should detect this installation and let you choose it for usein OpenOffice via the 'Tools - Options... - Java'. If you have a JRE installed that is not detected,you should be able to add it through this same menu. And, you can install a JRE or configure OpenOffice to use Java at anytime to get missing functionality to work.

Important note for Windows users:
The Windows version of OpenOffice is 32-bit and therefore it requires a 32-bit JRE. Even when you have a Windows versionwith 64-bit installed.
Furthermore you have to install a 32-bit JRE - additionally or instead - when you already have a64-bit JRE installed.

Where Can I Get Java?

The current versions of Apache OpenOffice work reliably with a variety of JREs includingOracle Java, versions 6, 7 and 8 andopenJDK, versions 6, 7 and 8. Feel free to download a JRE from either of these sitesif you feel you need this functionality.

Please report any problems you experience with using Java on OpenOffice through our bug reporting system,Bugzilla, or one of the other support venues listed in theApache OpenOffice Support webpage, either the users list or forums.
