<h3><a NAME="introduction"></a><u>Introduction</u></h3>
<p>Today's software market is a global one in which it is desirable to develop and
maintain one application that supports a wide variety of national languages. International
Components for Unicode for Java provides the following tools to help you write language
independent applications:
<ul type="disc">
<li>International Calendars – Arabic, Buddhist, Hebrew, Japanese</li>
<li>Unicode Normalization – Canonical text representation for W3C</li>
<li>Number Format Enhancements – Scientific Notation, Spelled-out, ...</li>
<li>Enhanced word-break detection – Rule-based, supports Thai</li>
<li>Unicode Text Searching – Efficient multi-lingual searching</li>
<li>Unicode Text Compression – 2:1 compression on English Unicode text</li>
</ul>
<p>Your comments are important to making this release successful. We are committed
to fixing any bugs, and will also use your feedback to help plan future releases. </p>

<h3><a NAME="WhatContain"></a><u>What the International Components for Unicode for Java
Contains</u></h3>
<p>There are two ways to download the ICU4J releases,
<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 ICU4J version of the ICU4J source code. These versions are tested
more thoroughly than day-to-day development builds, and they are packaged in zip and tar
files for convenient download. These packaged files can be found at <a
href="http://oss.software.ibm.com/developerworks/opensource/icu4j/download/index.html">http://oss.software.ibm.com/developerworks/opensource/icu4j/download/index.html</a>.
<br>
If packaged snapshot is named <b>ICU4JXXXXXX.zip </b>, XXXXXX is the release version
number. <br>
Please unzip this file. It will re-construct 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: <br>
<ul type="circle">
<li>WebCVS:<br>
If you want to browse the code and only make occasional downloads, you may want to use
WebCVS. It provides a convenient, web-based interface for browsing and downloading the
latest version of the ICU4J source code and documentation. You can also view each file's
revision history, display the differences between individual revisions, determine which
revisions were part of which official release, and so on. <br>
</li>
<li>WinCVS:<br>
If you will be doing serious work on ICU4J, you should probably install a CVS client on
your own machine so that you can do batch operations without going through the WebCVS
interface. On Windows, we suggest the WinCVS client. The following is the example
instruction on how to download ICU4J via WinCVS: <ol>
<li>Install the WinCVS client, which you can download from the WinCVS home page.</li>
<li>In the WinCVS preferences, specify your CVSRoot to be
":pserver:anoncvs@oss.software.ibm.com:/usr/cvs/icu4j" <br>
with the password "anoncvs". To enter the CVSRoot value, select
"Preferences" from the "Cvs Admin" pull-down menu.
Authentication should be set to "'passwd' file on the cvs server".</li>
<li>To "extract" the most recent version of ICU4J, select "Checkout
module" from the "Cvs Admin" menu. Specify "icu4j" for the module
name. <br>
</li>
</ol>
</li>
<li>CVS command line:<br>
You can also check out the repository anonymously on UNIX using the following commands,
after first setting your CVSROOT to point to the ICU4J repository: <pre><code>export CVSROOT=:pserver:anoncvs@oss.software.ibm.com:/usr/cvs/icu4j
cvs login CVS password: anoncvs
cvs checkout icu4j
cvs logout</code></pre>
</li>
</ul>
</li>
</ul>

</p>
<p>Below, <b>$Root</b> is the placement of the icu directory in your file system, like
"drive:\...\icu4j" in your environment. "drive:\..." stands for any
drive and any directory on that drive that you chose to install icu4j into. </p>

<h3><a NAME="PlatformDependencies"></a><u>Platform Dependencies</u></h3>
<p>Parts of ICU4J depend on functionality that is only available in Java2 (JDk1.2) or
later, although some components work under 1.1. However, all components should be
compiled using a Java2 compiler as even components that run using a 1.1.x JVM may require
language features that are only present in 1.2. Currently 1.1.x is unsupported and
untested and you use the components on a 1.1.x system at your own risk. </p>
<h3><a NAME="HowToInstallJavac"></a><u>How to Install and Build</u></h3>
<p>To install ICU4J, simply place the prebuilt jar file <strong>icu4j.jar</strong> on your
Java CLASSPATH. No other files are needed.</p>
<p>The prerequisites for building ICU4J are a working JDK and the Ant build system:
<ul>
<li>First install a recent JDK, at least version 1.2.</li>
<li>Next install the <a href="http://jakarta.apache.org/ant/"><strong>Ant</strong></a> build
system, part of the Apache Software Foundation's <a href="http://jakarta.apache.org/"><strong>Jakarta</strong></a>
project. 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.</li>
<li>Installing Ant is straightforward. Download it (see <a
href="http://jakarta.apache.org/downloads/binindex.html">http://jakarta.apache.org/downloads/binindex.html</a>),
extract it onto your system, set some environment variables, and add it's bin directory to
your path. See the current Ant documentation for details.</li>
<li>It's recommended to install both the JDK and Ant somewhere <em>outside</em> the ICU4J
directory, to keep them out of CVS's hair. For example, on Linux you might install these
in /usr/local.</li>
</ul>
<p>Once Ant is 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.</p>
<blockquote>
<pre>F:\icu4j>ant tests
Buildfile: build.xml
Project base dir set to: F:\icu4j
Executing Target: core
Compiling 71 source files to F:\icu4j\classes
Executing Target: tests
Compiling 24 source files to F:\icu4j\classes
Completed in 19 seconds</pre>
</blockquote>
<p>Current targets that you can give after <strong>ant</strong>:</p>
<div align="left">
<table border="1" cellpadding="0">
<tr>
<td>all</td>
<td>Build all targets.</td>
</tr>
<tr>
<td>core</td>
<td>Build the main class files in the subdirectory <strong>classes</strong>. If no target
is specified, core is assumed.</td>
</tr>
<tr>
<td>tests</td>
<td>Build the test class files.</td>
</tr>
<tr>
<td>demos</td>
<td>Build the demos.</td>
</tr>
<tr>
<td>tools</td>
<td>Build the tools.</td>
</tr>
<tr>
<td>docs</td>
<td>Run javadoc over the main class files, generating an HTML documentation tree in the
subdirectory <strong>docs</strong>.</td>
</tr>
<tr>
<td>jar</td>
<td>Create a jar archive <strong>icu4j.jar</strong> in the root ICU4J directory containing
the main class files.</td>
</tr>
<tr>
<td>zip</td>
<td>Create a zip archive of the source, docs, and jar file for
distribution, excluding unwanted things like CVS directories and
emacs backup files. The zip file
<strong>icu4jYYYYMMDD.zip</strong> will be created in the
directory <em>above</em> the root ICU4J directory, where YYYYMMDD
is today's date. Any existing file of that name will be
overwritten.</td>
</tr>
<tr>
<td>zipsrc</td>
<td>Like the <strong>zip</strong> target, without the docs and
the jar file. The zip file <strong>icu4jsrcYYYYMMDD.zip</strong>
will be created in the directory <em>above</em> the root ICU4J
directory.</td>
</tr>
<tr>
<td>clean</td>
<td>Remove all built targets, leaving the source.</td>
</tr>
</table>
</div>
<p>For more information, read the Ant documentation and the <strong>build.xml</strong>
file.</p>
<p>After doing a build it is a good idea to run all the tests by typeing "java
-classpath classes com.ibm.test.topleveltest.TestAll". </p>
<p>(As an alternative to using Ant, you can build simply by running javac and javadoc
directly. This is not recommended, but a Windows batch file "buildall.bat"
exists to get you started if you're really allergic to build systems. You may have to
create destination directories.)</p>
