<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 <a
|
||
href="http://www.wincvs.org">http://www.wincvs.org</a>.</li>
|
||
<li>Select <strong>Preferences</strong> from the <strong>Admin</strong> menu.<ol type="a">
|
||
<li>On the <strong>General</strong> tab panel: Set your <strong>CVSROOT</strong> to "<strong>:pserver:anoncvs@oss.software.ibm.com:/usr/cvs/icu4j</strong>".<br>
|
||
Leave other options on this page at their default.</li>
|
||
<li>On the <strong>Ports</strong> tab panel: Check the <strong>pserver</strong> checkbox and
|
||
enter port <strong>2401</strong>.</li>
|
||
</ol>
|
||
</li>
|
||
<li>Click on the Login menu button (<strong>Admin</strong> menu). Enter in "<strong>anoncvs</strong>" when requested.</li>
|
||
<li>To extract the most recent version of ICU4J, select <strong>Checkout module</strong>
|
||
from the <strong>Create</strong> menu. Specify "<strong>icu4j</strong>" for the
|
||
module name. This will create a new copy of the workspace on your local hard drive.</li>
|
||
<li>In the future, you can download updated files from the repository to your hard drive
|
||
using the <strong>Update selection</strong> item in the <strong>Modify</strong> menu.<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><b>Data organization:</b> </p>
|
||
|
||
<p>Data is stored in various locations in ICU4J:
|
||
|
||
<ul>
|
||
<li>Data that is "raw" data goes into <strong>$Root/src/data</strong>. This
|
||
includes things like the raw Unicode database. <strong>$Root/src/data</strong> does <em>not</em>
|
||
contain <strong>.java</strong> source files.</li>
|
||
<li>Data that is in the form of a Java class, typically a ResourceBundle, but not
|
||
necessarily, goes into one of the packages <code>com.ibm.util.resources</code> or <code>com.ibm.text.resources</code>,
|
||
depending on whether the associated code lives in <code>com.ibm.util</code> or <code>com.ibm.text</code>.</li>
|
||
<li>Data that is not part of ICU4J proper (or its base tool set), but rather part of a test,
|
||
sample, or demo, should go near the source code of its owner. This makes it easy to ship a
|
||
core ICU4J release without optional components.</li>
|
||
</ul>

<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 its bin directory to
|
||
your path. For example:<pre> set JAVA_HOME=C:\jdk1.2.2
|
||
set ANT_HOME=C:\jakarta-ant
|
||
set PATH=%PATH%;%ANT_HOME%\bin
|
||
call antsetup</pre>
|
||
<p>See the current Ant documentation for details.</p>
|
||
</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
|

|
||
<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.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>
