| <h1>Java & Apache OpenOffice, OpenOffice.org</h1> |
| |
| <h3>Why Do I Need Java to Use Apache OpenOffice?</h3> |
| |
| <p>Java is required for complete OpenOffice (OpenOffice.org) functionality. Java is mainly required for the HSQLDB |
| database 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 OpenOffice.org |
| and Apache OpenOffice in the |
| <a href="http://wiki.services.openoffice.org/wiki/Documentation/FAQ/Installation">Installation FAQ</a>. |
| </p> |
| |
| <p>So what does this mean exactly? Base (the database component) relies completely on Java technologies to run, but other |
| programs (like Writer, Calc and Impress) only need Java for special functionality. If you do not need to use Base and do |
| not want to use any of the Wizards, then you do not need to have Java installed and configured for running Apache |
| OpenOffice (and older versions of OpenOffice.org). You can completely prevent OpenOffice from prompting you about the use |
| of Java by telling OpenOffice not to use a Java runtime environment (JRE). From the OpenOffice main menu use: |
| <strong>"Tools - OpenOffice.org - Java"</strong>, and uncheck "Use a Java runtime environment". However, we do recommend |
| that you have a JRE on your system to take full advantage of OpenOffice's features without any issues. |
| </p> |
| |
| <p><b>Legacy versions of OpenOffice.org 3.3.0 and older included a JRE packaged with the download. Apache OpenOffice |
| 3.4.0 and newer do not.</b> |
| </p> |
| |
| <h3>Which Java Version Do I Need to Use Apache OpenOffice?</h3> |
| |
| <p>You will need to have a JRE version (32-bit or 64-bit) that is compatible with the architecture of the Apache |
| OpenOffice version you downloaded. If you already have a JRE installed on your system that satisfies this requirement in |
| one of the standard areas for Java installation, OpenOffice should detect this installation and let you choose it for use |
| in OpenOffice via the <strong>"Tools - OpenOffice.org - Java"</strong>. 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 any |
| time to get missing functionality to work. |

| <b>Important note for all Windows users:</b> |
| </br> |
| The Windows version of OpenOffice is 32-bit. It installs and operates on both 32-bit and 64-bit versions of Microsoft Windows. However, a 32-bit Java Runtime Environment is required for any use of a JRE by 32-bit applications such as Apache OpenOffice. The 32-bit JRE must be in addition to any 64-bit JRE that is also installed. |
| </p> |
| |
| <h3>Where Can I Get Java?</h3> |
| <p>The current versions of Apache OpenOffice work reliably with a variety of JREs including |
| <a href="http://java.com">Oracle Java, versions 6 and 7</a> and <a href="http://openjdk.java.net/">openJDK, versions 6 and |
| 7</a>. Feel free to download a JRE from either of these sites if you feel you need this functionality. |
| </p> |

| <p>Please report any problems you experience with using Java on OpenOffice through our bug reporting system, |
| <a href="https://issues.apache.org/ooo/">Bugzilla</a>, or one of the other support venues listed in the |
| <a href="http://www.openoffice.org/support/">Apache OpenOffice Support</a> webpage, either the users list or forums. |
