IBM played a key role in providing globalization technology to Sun for use in Java. Over the past seven years, the ICU team has continued to enhance and extend this technology. IBM makes this technology available in Java through the ICU4J open-source project.</p> <p>ICU4J provides the following tools: <ul> <li><b>Unicode Normalization</b> – NFC, NFD, NFKD, NFKC<br> Produces canonical text representations, needed for XML and the net. <li><b>International Calendars</b> – Arabic, Buddhist, Hebrew, and Japanese<br> Required for correct presentation of dates in some countries. <li><b>Number Format Enhancements</b> – Scientific Notation, Spelled-out Numbers<br> Enhances standard Java number formatting.

Unicode 5.0 will be used in many operating systems and applications, and this version of ICU is important maintain interoperability with these new operating systems and applications. More information about Unicode 5.0 can be found in the <a href="http://www.unicode.org/press/pr-ucd5.0.html">Unicode press release</a>.</li> <li><strong>Locale Data</strong>: ICU uses and supports data from <a href="http://www.unicode.org/press/pr-cldr1.4.html">Common Locale Data Repository (CLDR) 1.4</a>, which includes many improvements in quality and quantity of data. There is 25% more CLDR locale data in 245 locales in ICU.</li> <li><strong>Globalization Preferences</strong>: A new flexible container for locale data was added.</li> <li><strong>Formatting</strong>: A <strong>preview</strong> of the flexible date/time format generator has been added. This allows multiple date and time format patterns to be generated that are valid for specific locales.</li> <li><strong>Charset Conversion</strong>: A <strong>preview</strong> of the ICU4J implementation of the java.nio.charset.Charset API was added.</li> </ul> <p><i><font color="red"><strong>Note</strong>: Do not use preview APIs in production code. They may change drastically in subsequent releases.</font></i></p> <h3 class="doc"><a name="license"></a>License Information</h3> <p> The ICU projects (ICU4C and ICU4J) use the X license. The X license is <b>suitable for commercial use</b> and is a recommended free software license that is compatible with the GNU GPL license. This became effective with release 1.8.1 of ICU4C and release 1.3.1 of ICU4J in mid-2001. All new ICU releases will adopt the X license; previous ICU releases continue to utilize the IPL (IBM Public License). Users of previous releases of ICU who want to adopt new ICU releases will need to accept the terms and conditions of the X license. </p> <p> The main effect of the change is to provide GPL compatibility. The X license is listed as GPL compatible, see the GNU page at <a href="http://www.gnu.org/philosophy/license-list.html#GPLCompatibleLicenses"> http://www.gnu.org/philosophy/license-list.html#GPLCompatibleLicenses</a>. This means that GPL projects can now use ICU code, it does <b>not</b> mean that projects using ICU become subject to GPL. </p> <p> The IBM version contains the essential text of the license, omitting the X-specific trademarks and copyright notices. The full copy of <a href="license.html">ICU's license</a> is included in the download package. </p> <h3 class="doc"><a name="PlatformDependencies"></a>Platform Dependencies</h3> <p> By default ICU4J depends on functionality that is only available in JDK 1.4. We provide the ability to build a variant of ICU4J that will run on JDK 1.3, but not all build targets work on that platform. Currently 1.1.x and 1.2.x JVMs are unsupported and untested, and you use the components on these JVMs at your own risk.</p> <p> The reference platforms which we support and test ICU4J on are:</p> <ul> <li> WinXP, IBM JDK 1.5.0</li> <li> Solaris 5.9, Sun JDK 1.5.0</li> <li> AIX 5.2, IBM JDK 1.5.0</li> </ul> <p>Please use the most recent updates of the supported JDK versions.</p> <p>Additionally, we have built and tested ICU4J on the following <b>unsupported</b> platforms (note, only some build/test targets work on 1.3 platforms): </p> <ul> <li> WinXP / IBM JDK 1.4.2, 1.4.1, Sun JDK 1.5.0, 1.4.2</li> <li> Solaris 5.6 , Solaris 5.7 / Sun JDK 1.4.2, 1.4.1, 1.4.0</li> <li> Solaris 5.9 / Sun JDK 1.4.2, 1.4.1, 1.4.0</li> <li> AIX 5.2 / IBM JDK 1.4.2, 1.4.1</li> <li> AIX 5.1 / IBM JDK 1.4.2, 1.4.1</li> <li> RedHat Enterprise Linux 3/ IBM JDK 1.5.0, 1.4.2, Sun JDK 1.5.0, 1.4.2, 1.4.1, 1.4.0</li> <li> HP UX Sun JDK 1.5.0, 1.4.2</li> </ul> <h3 class="doc"><a name="download"></a>How to Download ICU4J</h3> <p>There are two ways to download the ICU4J releases. </p> <ul type="disc"> <li><b>Official Release Snapshot:</b><br> If you want to use ICU4J (as opposed to developing it), your best bet is to download an official, packaged version of the ICU4J source code. These versions are tested more thoroughly than day-to-day development builds, and they are packaged in jar files for convenient download. These packaged files can be found at the <a href="http://icu.sourceforge.net/download/">ICU Downloads page</a>. A packaged snapshot is named <b>icu4j-XXX-src.jar</b>, where XXX is the release version number. Please unjar this file. It will reconstruct the source directory.</li> </ul> <ul type="disc"> <li><b>CVS Source Repository:</b><br> If you are interested in developing features, patches, or bug fixes for ICU4J, you should probably be working with the latest version of the ICU4J source code. You will need to check the code out of our CVS repository to ensure that you have the most recent version of all of the files. There are several ways to do this. Please follow the directions that are contained on the <a href="http://www.ibm.com/software/globalization/icu/repository.jsp">Source Repository page</a> for details. </li> </ul> <p>For more details on how to download ICU4J directly from the web site, please see the ICU downloads page at <a href="http://icu.sourceforge.net/download/">http://icu.sourceforge.net/download/</a> </p> <h3 class="doc"><a name="WhatContain"></a>The Structure and Contents of ICU4J</h3> <p>Below, <b>$Root</b> is the placement of the icu directory in your file system, like "drive:\...\icu4j" in your environment.

If you need Charset API support please place <strong>icu4j-charsets.jar</strong> on your class path. No other files are needed.</p> <p><b>Eclipse users:</b> See the ICU4J site for information on<a href="http://icu.sourceforge.net/docs/eclipse_howto/eclipse_howto.html"> how to configure Eclipse</a> to build ICU4J.</p> <p>To build ICU4J, you will need a Java2 JDK and the Ant build system. We strongly recommend using the Ant build system to build ICU4J. It's recommended to install both the JDK and Ant somewhere <em>outside</em> the ICU4J directory. For example, on Linux you might install these in /usr/local.</p> <ul> <li>Install a recent JDK, version 1.4.x will work.</li> <li>Install the <a href="http://ant.apache.org/"><strong>Ant</strong></a> build system. Ant is a portable, Java-based build system similar to make. ICU4J uses Ant because it introduces no other dependencies, it's portable, and it's easier to manage than a collection of makefiles. We currently build ICU4J using a single makefile on both Windows 9x and Linux using Ant. The build system requires Ant 1.6 or later. <p>Installing Ant is straightforward. Download it (see <a href="http://ant.apache.org/bindownload.cgi">http://ant.apache.org/bindownload.cgi</a>), extract it onto your system, set some environment variables, and add its bin directory to your path. For example: </p> <pre> set JAVA_HOME=C:\jdk1.5.0<br> set ANT_HOME=C:\ant<br> set PATH=%PATH%;%ANT_HOME%\bin</pre> <p>See the current Ant documentation for details.</p> </li> </ul> <p>Once the JDK and Ant are installed, building is just a matter of typing <strong>ant</strong> in the ICU4J root directory. This causes the Ant build system to perform a build as specified by the file <strong>build.xml</strong>, located in the ICU4J root directory. You can give Ant options like -verbose, and you can specify targets. Ant will only build what's been changed and will resolve dependencies properly. For example:</p> <blockquote> <pre>F:\icu4j>ant tests<br>Buildfile: build.xml<br>Project base dir set to: F:\icu4j<br>Executing Target: core<br>Compiling 71 source files to F:\icu4j\classes<br>Executing Target: tests<br>Compiling 24 source files to F:\icu4j\classes<br>Completed in 19 seconds</pre> </blockquote> <i>Note: The above output is an example. The numbers are likely to be different with the current version ICU4J.</i> <p>The following are some targets that you can provide to <b>ant</b>.

ICU4J release 2.6 and later provide build options to build individual ICU4J 'modules' for a more compact distribution. The modules are based on a service and the APIs that define it, e.g., the normalizer module supports all the APIs of the Normalizer class (and some others). Tests can be run to verify that the APIs supported by the module function correctly. Because of internal code dependencies, a module contains extra classes that are not part of the module's core service API. Some or most of the APIs of these extra classes will not work. <b>Only the module's core service API is guaranteed.</b> Other APIs may work partially or not at all, so client code should avoid them.</p> <p> Individual modules are not built directly into their own separate jar files. Since their dependencies often overlap, using separate modules to 'add on' ICU4J functionality would result in unwanted duplication of class files. Instead, building a module causes a subset of ICU4J's classes to be built and put into ICU4J's standard build directory. After one or more module targets are built, the 'moduleJar' target can then be built, which packages the class files into a 'module jar.' Other than the fact that it contains fewer class files, little distinguishes this jar file from a full ICU4J jar file, and in fact they share the same name.</p> <p> Currently ICU4J can be divided into the following modules: </p> <p><b>Key:</b></p> <table bgcolor="#ccccff" cellpadding="3" frame="void" width="623"> <tbody> <tr> <th align="left" valign="baseline"><b>Module Name</b></th> <th align="left" valign="baseline"><b>Ant Targets</b></th> <th align="left" valign="baseline"><b>Test Package Supported</b></th> <th align="right" valign="baseline"><b>Size<7A></b></th> </tr> <tr bgcolor="#ffffff"> <td colspan="4"> <table> <tbody> <tr> <td valign="baseline">Package*</td> <td valign="baseline">Main Classes<65> </td> </tr> </tbody> </table> </td> </tr> </tbody> </table> <b><font size="2">* com.ibm. should be prepended to the package names listed. <br> <0A> Class name in bold indicates core service API.

--> </tbody> </table> <p>Building any of these modules is as easy as specifying a build target to the Ant build system, e.g: <br> To build a module that contains only the Normalizer API: </p> <ol> <li> Build the module. <br> <code> ant normalizer </code> </li> <li> Build the jar containing the module. <br> <code>ant moduleJar </code> </li> <li> Build the tests for the module. <br> <code> ant normalizerTests </code> </li> <li> Run the tests and verify that the self tests pass. <br> <code> java -classpath $icu4j_root/classes com.ibm.icu.dev.test.TestAll -nothrow -w </code> </li> </ol> If more than one module is required, the module build targets can be concatenated, e.g: <ol> <li> Build the modules. <br> <code> ant normalizer collator </code> </li> <li> Build the jar containing the modules. <br> <code>ant moduleJar </code> </li> <li> Build the tests for the module. <br> <code> ant normalizerTests collatorTests </code> </li> <li> Run the tests and verify that they pass. <br> <code> java -classpath $icu4j_root/classes com.ibm.icu.dev.test.TestAll -nothrow -w </code> </li> </ol> The jar should be built before the tests, since for some targets building the tests will cause additional classes to be compiled that are not strictly necessary for the module itself. <h5> Notes: </h5> <ul> <li>Regardless of whether ICU4J is built as a whole or as modules, the jar file produced is named <em>icu4j.jar</em>.</li> <li>To ascertain if an icu4j.jar contains all of ICU4J or not, please see the manifest file in the jar</li> <li>The target moduleJar does not depend on any other

It just creates a jar of all class files under $icu4j_root/classes/com/ibm/icu/, excluding the classs files in $icu4j_root/classes/com/ibm/icu/dev folder</li> <li>The list of module build targets can be obtained by running the command: <code>ant -projecthelp</code></li> </ul> <h3 class="doc"><a name="tryingout"></a>Trying Out ICU4J</h3> <p><strong>Note:</strong> the demos provided with ICU4J are for the most part undocumented. This list can show you where to look, but you'll have to experiment a bit. The demos (with the exception of richedit) are <strong>unsupported</strong> and may change or disappear without notice.</p> <p>The icu4j.jar file contains only the core ICU4J classes, not the demo classes, so unless you build ICU4J there is little to try out. </p> <h4>Charset</h4> To try out the <strong>Charset</strong> package, build <strong>icu4j.jar</strong> and <strong>icu4j-charsets.jar</strong> using 'jar' target. You can use the charsets by placing these files on your classpath. <blockquote><tt>java -cp $Root/icu4j.jar:$Root/icu4j-charsets.jar <your program></tt></blockquote> <h4>Rich Edit</h4> To try out the <strong>richedit</strong> package, first build the richeditJar target. This is a 'runnable' jar file. To run the richedit demo, type: <blockquote><tt>java -jar $Root/richedit/richedit.jar</tt></blockquote> This will present an empty edit pane with an awt interface. <p>With a fuller command line you can try out other options, for example:</p> <blockquote><tt>java -classpath $Root/richedit/richedit.jar com.ibm.richtext.demo.EditDemo [-swing][file]</tt></blockquote> <p>This will use an awt GUI, or a swing GUI if <tt>-swing</tt> is passed on the command line. It will open a text file if one is provided, otherwise it will open a blank page. Click to type.</p> <p> You can add tabs to the tab ruler by clicking in the ruler while holding down the control key. Clicking on an existing tab changes between left, right, center, and decimal tabs. Dragging a tab moves it, dragging it off the ruler removes it.</p> <p> You can experiment with complex text by using the keymap functions. Please note that these are mainly for demo purposes, for real work with Arabic or Hebrew you will want to use an input method. You will need to use a font that supports Arabic or Hebrew, 'Lucida Sans' (provided with Java) supports these languages.</p> <h4>Other demos</h4> <p>The other demo programs are <strong>not supported</strong> and exist only to let you experiment with the ICU4J classes. First, build ICU4J using <tt>ant all</tt>. Then try one of the following: </p> <ul> <li><tt>java -classpath classes com.ibm.icu.dev.demo.calendar.CalendarApp</tt> </li> <li><tt>java -classpath classes com.ibm.icu.dev.demo.holiday.HolidayCalendarDemo</tt> </li> <li><tt>java -classpath classes com.ibm.icu.dev.demo.rbbi.TextBoundDemo</tt><br> (Click in the text, then use <tt>ctrl-N</tt> and <tt>ctrl-P</tt> to select the next or previous block of text.) </li> <li><tt>java -classpath classes com.ibm.icu.dev.demo.rbnf.RbnfDemo</tt> </li> <li><tt>java -classpath classes com.ibm.icu.dev.demo.translit.Demo</tt> </li> </ul> <h3 class="doc"><a name="resources">ICU4J Resource Information</a></h3> Starting with release 2.1, ICU4J includes its own resource information which is completely independent of the JDK resource information. (Note, in ICU4J 3.2 and 3.4, time zone information still depends on the underlying JDK). The new ICU4J information is equivalent to the information in ICU4C and many resources are, in fact, the same binary files that ICU4C uses. <p> By default the ICU4J distribution includes all of the standard resource information. It is located under the directory com/ibm/icu/impl/data. Depending on the service, the data is in different locations and in different formats. <strong>Note:</strong> This will continue to change from release to release, so clients should not depend on the exact organization of the data in ICU4J.</p> <ul> <li>The primary <b>locale data</b> is under the directory <tt>icudt36b</tt>, as a set of <tt>".res"</tt> files whose names are the locale identifiers. Locale naming is documented the <code>com.ibm.icu.util.ULocale</code> class, and the use of these names in searching for resources is documented in <code>java.util.ResourceBundle</code>. </li> <li>The <b>collation data</b> is under the directory <tt>icudt36b/coll</tt>, as a set of <tt>".res"</tt> files.</li> <li>The <b>rule-based transliterator data</b> is under the directory <tt>icudt36b/translit</tt> as a set of <tt>".res"</tt> files. (<b>Note:</b> the Han transliterator test data is no longer included in the core icu4j.jar file by default.)</li> <li>The <b>rule-based number format data</b> is under the directory <tt>icudt36b/rbnf</tt> as a set of <tt>".res"</tt> files. <li>The <b>break iterator data</b> is directly under the data directory, as a set of <tt>".brk"</tt> files, named according to the type of break and the locale where there are locale-specific versions.</li> <li>The <b>holiday data</b> is under the <tt>data</tt> directory, as a set of <tt>".class"</tt> files, named <tt>"HolidayBundle_"</tt> followed by the locale ID.</li> <li>The <b>character property data</b> as well as assorted <b>normalization data</b> and default <b>unicode collation algorithm (UCA) data</b> is found under the <tt>data</tt> directory as a set of <tt>".icu"</tt> files. </li> </ul> <p> Some of the data files alias or otherwise reference data from other data files. One reason for this is because some locale names have changed. For example, <tt>he_IL</tt> used to be <tt>iw_IL</tt>. In order to support both names but not duplicate the data, one of the resource files refers to the other file's data. In other cases, a file may alias a portion of another file's data in order to save space. Currently ICU4J provides no tool for revealing these dependencies.</p> <blockquote><strong>Note:</strong> Java's <code>Locale</code> class silently converts the language code <tt>"he"</tt> to <tt>"iw"</tt> when you construct the Locale (for versions of Java through Java 5). Thus Java cannot be used to locate resources that use the <tt>"he"</tt> language code. ICU, on the other hand, does not perform this conversion in ULocale, and instead uses aliasing in the locale data to represent the same set of data under different locale ids.</blockquote> <p> Resource files that use locale ids form a hierarchy, with up to four levels: a root, language, region (country), and variant. Searches for locale data attempt to match as far down the hierarchy as possible, for example, <tt>"he_IL"</tt> will match <tt>he_IL</tt>, but <tt>"he_US"</tt> will match <tt>he</tt> (since there is no <tt>US</tt> variant for he, and <tt>"xx_YY</tt> will match root (the default fallback locale) since there is no <tt>xx</tt> language code in the locale hierarchy. Again, see <code>java.util.ResourceBundle</code> for more information. </p> <p> <strong>Currently ICU4J provides no tool for revealing these dependencies</strong> between data files, so trimming the data directly in the ICU4J project is a hit-or-miss affair. The key point when you remove data is to make sure to remove all dependencies on that data as well. For example, if you remove <tt>he.res</tt>, you need to remove <tt>he_IL.res</tt>, since it is lower in the hierarchy, and you must remove iw.res, since it references <tt>he.res</tt>, and <tt>iw_IL.res</tt>, since it depends on it (and also references <tt>he_IL.res</tt>). </p> <p> Unfortunately, the jar tool in the JDK provides no way to remove items from a jar file. Thus you have to extract the resources, remove the ones you don't want, and then create a new jar file with the remining resources. See the jar tool information for how to do this. Before 'rejaring' the files, be sure to thoroughly test your application with the remaining resources, making sure each required resource is present. </p> <h4>Using additional resource files with ICU4J</h4> <blockquote> <table cellpadding="3" frame="border" rules="none" width="50%"> <tbody> <tr> <td><b><font color="red" size="+1">Warning:</font> Resource file formats can change across releases of ICU4J!</b></td> </tr> <tr> <td>The format of ICU4J resources is not part of the API. Clients who develop their own resources for use with ICU4J should be prepared to regenerate them when they move to new releases of ICU4J.</td> </tr> </tbody> </table> </blockquote> <p> We are still developing ICU4J's resource mechanism. Currently it is not possible to mix icu's new binary <tt>.res</tt> resources with traditional java-style <tt>.class</tt> or <tt>.txt</tt> resources. We might allow for this in a future release, but since the resource data and format is not formally supported, you run the risk of incompatibilities with future releases of ICU4J. </p> <p> Resource data in ICU4J is checked in to the repository as a jar file containing the resource binaries, <tt>icudata.jar</tt>. This means that inspecting the contents of these resources is difficult. They currently are compiled from ICU4C <tt>.txt</tt> file data. You can view the contents of the ICU4C text resource files to understand the contents of the ICU4J resources. </p> <p> The files in <tt>icudata.jar</tt> get extracted to <tt>com/ibm/icu/impl/data</tt> in the build directory when the 'core' target is built. Building the <tt>'resources'</tt> target will force the resources to once again be extracted.
