Java & OpenOffice.org

Java is required for complete OpenOffice.org functionality. Java is mainly required to use the new embedded Java technology based HSQLDB database engine, or to make use of accessibility and assistive technologies. If you do not require database tables or accessibility integration or some wizards, then you do not need to download and install Java. Base (the database component) for example completely relies on Java technologies to run, but other programs (like Writer, Calc and Impress) only need Java for special functionality.

If you have already Java installed there is no need to download the OpenOffice.org installer with Java.

If you choose not to download Java you can easily install Java afterwards to get the missing functionality to work.

The Java Runtime Environment (JRE) or complete Java Development Kit (JDK) can be downloaded from java.com.

For installing Java on Windows machines, one might appreciate: Download Instructions for Windows offline.
