Localization is performed by simply adding locale-specific components, such as translated text, data describing locale-specific behavior, fonts and input methods.</p> <h2>Source Structure</h2> <p>Source for the internationalization libraries is found throughout the JDK workspace. Typically, directories under <code>src/share/classes/java</code> contain the classes and interfaces of the public APIs. Often the implementations of these APIs reside in the corresponding <code>src/share/classes/sun</code> directories. Source that is platform dependent (e.g., input methods) may also reside under the <code>src/[solaris|windows]</code> directories.</p> <p>Here are some of the locations of the core internationalization libraries.</p> <ul> <li> <p><code>src/share/classes/java/lang</code>:<br /> Contains source for the <code>Character</code> and <code>String</code> classes which implement the <a href="https://www.unicode.org/ucd/">Unicode Character Database</a>.</p> </li> <li> <p><code>src/share/classes/java/text</code>:<br /> Contains source for classes providing locale sensitive services such as <code>DateFormat</code>, <code>NumberFormat</code>, <code>Collator</code>, <code>Normalizer</code>, <code>Bidi</code>, <code>BreakIterator</code>, etc.</p> </li> <li> <p><code>src/share/classes/java/util</code>:<br /> Contains source for locale utility classes such as <code>Locale</code>, <code>Currency</code>, <code>Calendar</code>, <code>TimeZone</code>, <code>ResourceBundle</code>, etc.</p> </li> <li> <p><code>src/share/classes/sun/[text|util]/resources</code>:<br /> Contains the locale data needed for the above locale sensitive classes.</p> </li> <li> <p><code>src/share/classes/java/awt/im</code>:<br /> Contains source for the API classes of the <a href="http://java.sun.com/javase/6/docs/technotes/guides/imf/index.html"> Input Method Framework</a>.</p> </li> <li> <p><code>src/share/classes/sun/awt/im</code>:<br /> Contains source for the implementation classes of the <a href="http://java.sun.com/javase/6/docs/technotes/guides/imf/index.html"> Input Method Framework</a>.</p> </li> <li> <p><code>src/solaris/classes/sun/awt/fontconfigs</code>, <code>src/windows/classes/sun/awt/windows</code>:<br /> Contains source for the <a href="http://java.sun.com/javase/6/docs/technotes/guides/intl/fontconfig.html"> font configuration files</a></p> </li> </ul> <h2>Building and Rebuilding</h2> <p>After building the whole JDK tree, output class files will be generated under the corresponding directories under <code>build/classes</code> directory. Some of the locale data will be incorporated in the <code>build/lib/ext/localedata.jar</code> file. To rebuild the internationalization library sources, you may want to run <code>gnumake</code> in the following directories:</p> <ul> <li><code>make/java/java</code></li> <li><code>make/java/text</code></li> <li><code>make/java/util</code></li> <li><code>make/java/awt</code></li> </ul> <h2>Documentation</h2> <ul> <li><a href="http://java.sun.com/javase/6/docs/technotes/guides/intl/">Internationalization Support</a></li> </ul> <h2>Community</h2> <ul> <li><strong>Mailing lists</strong> <ul> <li><a href="https://mail.openjdk.org/mailman/listinfo/i18n-dev">i18n-dev</a></li> </ul> </li> </ul> <ul> <li><strong>Internationalization bloggers</strong> <ul> <li><a href="http://blogs.oracle.com/naotoj/">Naoto Sato</a></li> <li><a href="http://blogs.oracle.com/masayoshi/">Masayoshi Okutsu</a></li> </ul> </li> </ul> <a name="l10n" id="l10n"></a> <h1>The Localization Group</h1> The localization group is comprised of developers and translators interested in localizing JRE and JDK into various languages.<br /> <br /> Activities include contributing translation or linguistic review, validating and providing locale data, providing other locale-specific features into Java, or maintaining/bug fixing existing localization bugs.<br /> <h2>Introduction</h2> Until Java 6, user interface provided in both JRE and JDK have been localized into following languages.<br /> <br /> <table class="wikitable" border="1" summary="Localized Languages"> <tbody> <tr> <td>Language</td> <td>JRE</td> <td>JDK</td> </tr> <tr> <td>Chinese (Simplified)</td> <td>O</td> <td>O</td> </tr> <tr> <td>Chinese (Traditional)</td> <td>O</td> <td><br /></td> </tr> <tr> <td>English</td> <td>O</td> <td>O</td> </tr> <tr> <td>French</td> <td>O</td> <td><br /></td> </tr> <tr> <td>German</td> <td>O</td> <td><br /></td> </tr> <tr> <td>Italian</td> <td>O</td> <td><br /></td> </tr> <tr> <td>Japanese</td> <td>O</td> <td>O</td> </tr> <tr> <td>Korean</td> <td>O</td> <td><br /></td> </tr> <tr> <td>Spanish</td> <td>O</td> <td><br /></td> </tr> <tr> <td>Swedish</td> <td>O</td> <td><br /></td> </tr> </tbody> </table> <br /> JRE includes user interface elements such as Swing dialogs, runtime messages, and tools messages. JDK includes user interface elements for additional tools such as compiler, JConsole, javadoc, demos, etc.<br /> <h2>Source Files</h2> Localization resource files are distributed throughout the JDK workspace. They are usually located in the resources directories for each component.<br /> <br /> Below are some of the locations of the localizable resource files.<br /> <br /> rt.jar (jre)<br />

make/common/Defs.gmk in j2se workspace, which means update j2se/make/common/Defs.gmk<br /> <br /> in following two lines, add the locale you are going to localize.<br /> <br /> J2RE_LOCALES = de es fr it ja ko sv zh_CN zh_TW zh_HK<br /> PLUGIN_LOCALES = de es fr it ja ko sv zh_CN zh_TW zh_HK<br /> <br /> For example, if you are going to localize JRE into thai, then<br /> J2RE_LOCALES = de es fr it ja ko sv th zh_CN zh_TW zh_HK<br /> PLUGIN_LOCALES = de es fr it ja ko sv th zh_CN zh_TW zh_HK<br /> <br /> update make/common/Defs.gmk in deploy workspace.<br /> In follwoing line, add the locale you are goingto localize<br /> PLUGIN_LOCALES = de es fr it ja ko sv zh_CN zh_TW zh_HK<br /> <br /> <b>Include locale in JDK</b><br /> update make/common/Defs.gmk in j2se workspace<br /> in following line, add the locale you are going to localize.<br /> <br /> J2SDK_LOCALES = ja zh_CN<br /> <br /> Notes: It's not mentioned how to include locale in install ws, to localize the installshield of JRE and JDK in windows. It's related with many changes, and will be described later.<br /> <h2>Building and Rebuilding</h2> After building the whole JDK tree, the localization related resource files can be found in various jar files such as rt.jar, localdata.jar, tools.jar, jconsole.jar, resources.jar, indicim.jar, thaiim.jar, etc.<br /> <br /> <h2>Additional Localization Projects</h2> You may also be interested in
