< p > The International Components for Unicode (ICU) library provides
robust and
full-featured Unicode services on a wide variety of platforms. ICU
supports the

most current version of the Unicode standard, including support for
supplementary characters (needed for GB 18030 repertoire support).< / p >

up with evolving standards. The ICU team continues to extend Java's

Unicode and internationalization support, focusing on improving
performance,
keeping current with the Unicode standard, and providing richer APIs,
while

remaining as compatible as possible with the original Java text and
internationalization API design.< / p >

2007-08-30 23:51:41 +00:00
< p > < b > Changes to J2SE version requirement for building ICU4J< / b >
< p > Previous version of ICU4J was successfully built with J2SE SDK 1.4 or later
versions. In this release, there is a new feature which uses a new type introduced
in J2SE 5.0. Although the new feature does not need the type available at run time,
it requires J2SE 5.0 or newer version of Java class library at the build time to enable
the feature. The binary distribution version of ICU4J available at the ICU download
page was built with J2SE SDK 5.0 and this version should work well on JRE 1.4 or later
versions. If you want to build your own copy of ICU4J binaries with J2SE SDK 1.4,
you can still run all of the Ant standard build targets in build.xml and make ICU4J
binaries. The build script detects the current Java version and comments out code
blocks including references to J2SE 5.0 only types.< / p >
2007-09-14 03:06:52 +00:00
< p > < b > Changes to timezone formatting and parsing< / b >
< p > In ICU 3.8, the behavior of date formatting and parsing has changed
significantly, perhaps requiring recoding on your part depending on your
usage. For more information, see < a href = "http://icu-project.org/userguide/formatDateTime.html" >
Formatting Dates and Times< / a > in the User Guide.

< p > < b > Status of ICU4J charset converter< / b >
< p > The ICU4J implementation of java.nio.charset.Charset is included as a Technology
Preview. Not all functionality from the java.nio.Charset interfaces is operational,
and some converters are known to mis-handle Unicode supplementary characters. Use with caution.

The ICU projects (ICU4C and ICU4J) use the X license. The X
2005-07-26 21:44:58 +00:00
license is < b > suitable for commercial use< / b > and is a recommended free software license
2005-02-18 00:19:33 +00:00
that is compatible with the GNU GPL license. This became
2004-11-09 23:35:01 +00:00
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
2005-02-18 00:19:33 +00:00
releases continue to utilize the IPL (IBM Public License). Users
2004-11-09 23:35:01 +00:00
of previous releases of ICU who want to adopt new ICU releases will
need to accept the terms and conditions of the X license.

2005-02-18 00:19:33 +00:00
The main effect of the change is to provide GPL compatibility.
2005-07-26 21:44:58 +00:00
The X license is listed as GPL compatible, see the GNU page at

< p > By default ICU4J depends on functionality that is only available
2007-08-30 23:51:41 +00:00
in J2SE 1.4 or later releases. Some new ICU4J features support types
introduced in J2SE 5, you can still use the same ICU4J binaries on JRE
1.4. We provide the ability to build a variant of ICU4J that will run
on JRE 1.3, but not all build targets work on that platform. Currently
1.1.x and 1.2.x JREs are unsupported and untested, and you use the
components on these JREs at your own risk.

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
2005-02-18 00:19:33 +00:00
code. These versions are tested more thoroughly than day-to-day
2005-07-26 21:44:58 +00:00
development builds, and they are packaged in jar files for convenient
download. These packaged files can be found at the < a
2007-08-04 02:07:57 +00:00
href="http://www.icu-project.org/download/">ICU Downloads page< / a > .
2006-09-29 21:03:27 +00:00
A packaged snapshot is named < b > icu4j-XXX-src.jar< / b > , where XXX
2005-07-26 21:44:58 +00:00
is the release version number. Please unjar this file. It
will reconstruct the source directory.< / li >

If you are interested in developing features, patches, or bug fixes for
ICU4J, you should probably be working with the latest version of the
2007-08-04 02:07:57 +00:00
ICU4J source code. You will need to check the code out of our Subversion
2004-11-09 23:35:01 +00:00
repository to ensure that you have the most recent version of all of
2005-02-18 00:19:33 +00:00
the files. There are several ways to do this. Please follow the
directions that are contained on the < a

how to configure Eclipse< / a > to build ICU4J.< / p >
2007-08-30 23:51:41 +00:00
< p > To build ICU4J, you will need a J2SE SDK and the Ant build system.
2004-11-23 20:09:14 +00:00
We strongly recommend using the Ant build system to build ICU4J.
2007-08-30 23:51:41 +00:00
It's recommended to install both the J2SE SDK and Ant somewhere < em > outside< / em >
2004-11-09 23:35:01 +00:00
the ICU4J directory. For example, on Linux you might install these in
2004-11-23 20:09:14 +00:00
/usr/local.< / p >
< ul >
2007-08-30 23:51:41 +00:00
< li > Install J2SE SDK 5.0. (You can use any version of J2SE SDK 1.4 or newer,
but for J2SE SDK 5.0 is required to enable the all available ICU4J features.)< / li >
2004-11-23 20:09:14 +00:00
< li > Install the < a href = "http://ant.apache.org/" > < strong > Ant< / strong > < / a >
2004-11-09 23:35:01 +00:00
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
2007-08-30 23:51:41 +00:00
currently build ICU4J using a single makefile on all platforms Ant.
The build system requires Ant 1.6 or later.
2001-11-30 20:48:48 +00:00
< p > Installing Ant is straightforward. Download it (see < a
2004-11-09 23:35:01 +00:00
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 >
2007-08-30 23:51:41 +00:00
< pre >
set JAVA_HOME=C:\jdk1.5.0
set ANT_HOME=C:\ant
set PATH=%PATH%;%ANT_HOME%\bin< / pre >
2000-09-21 21:49:12 +00:00
< p > See the current Ant documentation for details.< / p >
< / li >
2000-04-14 00:21:00 +00:00
< / ul >
2007-08-30 23:51:41 +00:00
< p > Once the J2SE SDK and Ant are installed, building is just a matter of
2001-11-30 20:48:48 +00:00
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
2004-11-09 23:35:01 +00:00
properly. For example:< / p >

< p > Some clients may not wish to ship all of ICU4J with their
application, since the application might only use a small part of
ICU4J.
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 >

Currently ICU4J can be divided into the following modules:

< p > Building any of these modules is as easy as specifying a build

< li > Build the module. < br >
< code > ant normalizer < / code > < / li >
< li > Build the jar containing the module. < br >

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 >

2004-11-09 23:35:01 +00:00
< / 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.

Starting with release 2.1, ICU4J includes its own
2002-08-15 17:39:50 +00:00
resource information
2007-08-30 23:51:41 +00:00
which is completely independent of the JRE resource information. (Note,
ICU4J 2.8 to 3.4, time zone information depends on the underlying JRE).
2007-08-04 02:07:57 +00:00
The new ICU4J information is equivalent to the information in ICU4C and
many resources are, in fact, the same binary files that ICU4C uses.
2002-08-15 17:39:50 +00:00

information. It is located under the directory com/ibm/icu/impl/data.
2004-06-15 22:59:13 +00:00
Depending on the service, the data is in different locations and in
2004-11-09 23:35:01 +00:00
different formats. < strong > Note:< / strong > This will continue to change

Some of the data files alias or otherwise reference data from other
data files. One reason for this is because some locale names have
2004-11-09 23:35:01 +00:00
changed. For example, < tt > he_IL< / tt > used to be < tt > iw_IL< / tt > . In
2004-06-15 22:59:13 +00:00
order to support both names but not duplicate the data, one of the
2004-11-09 23:35:01 +00:00
resource files refers to the other file's data. In other cases, a
2004-06-15 22:59:13 +00:00
file may alias a portion of another file's data in order to save
2004-11-09 23:35:01 +00:00
space. Currently ICU4J provides no tool for revealing these
dependencies.< / p >

< blockquote > < strong > Note:< / strong > Java's < code > Locale< / code > class
2004-11-09 23:35:01 +00:00
silently converts the language code < tt > "he"< / tt > to < tt > "iw"< / tt >
2005-07-26 21:44:58 +00:00
when you construct the Locale (for versions of Java through Java 5). Thus
2004-06-15 22:59:13 +00:00
Java cannot be used to locate resources that use the < tt > "he"< / tt >
2004-11-09 23:35:01 +00:00
language code. ICU, on the other hand, does not perform this
2004-06-15 22:59:13 +00:00
conversion in ULocale, and instead uses aliasing in the locale data to
represent the same set of data under different locale
ids.< / blockquote >

< p >
2004-06-15 22:59:13 +00:00
Resource files that use locale ids form a hierarchy, with up to four
2004-11-09 23:35:01 +00:00
levels: a root, language, region (country), and variant. Searches for
2004-06-15 22:59:13 +00:00
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 >
2004-11-09 23:35:01 +00:00
variant for he, and < tt > "xx_YY< / tt > will match root (the
2004-06-15 22:59:13 +00:00
default fallback locale) since there is no < tt > xx< / tt > language code
2004-11-09 23:35:01 +00:00
in the locale hierarchy. Again, see
2004-06-15 22:59:13 +00:00

< strong > Currently ICU4J provides no tool for revealing these
dependencies< / strong > between data files, so trimming the data
2004-11-09 23:35:01 +00:00
directly in the ICU4J project is a hit-or-miss affair. The key point
2004-06-15 22:59:13 +00:00
when you remove data is to make sure to remove all dependencies on
2004-11-09 23:35:01 +00:00
that data as well. For example, if you remove < tt > he.res< / tt > , you
2004-06-15 22:59:13 +00:00
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 > ).
2002-08-15 17:39:50 +00:00
< / p >
< p >
Unfortunately, the jar tool in the JDK provides no way to remove items
2004-11-09 23:35:01 +00:00
from a jar file. Thus you have to extract the resources, remove the
2002-08-15 17:39:50 +00:00
ones you don't want, and then create a new jar file with the remining
2004-11-09 23:35:01 +00:00
resources. See the jar tool information for how to do this. Before
2002-08-15 17:39:50 +00:00
'rejaring' the files, be sure to thoroughly test your application with
the remaining resources, making sure each required resource is
present.

prepared to
regenerate them when they move to new releases of ICU4J.< / td >

We are still developing ICU4J's resource mechanism. Currently it
is not possible to mix icu's new binary < tt > .res< / tt >
2004-11-09 23:35:01 +00:00
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.

Resource data in ICU4J is checked in to the repository as a jar file
2004-11-09 23:35:01 +00:00
containing the resource binaries, < tt > icudata.jar< / tt > . This
2004-06-15 22:59:13 +00:00
means that inspecting the contents of these resources is difficult.
2004-11-09 23:35:01 +00:00
They currently are compiled from ICU4C < tt > .txt< / tt > file data. You
2004-06-15 22:59:13 +00:00
can view the contents of the ICU4C text resource files to understand
the contents of the ICU4J resources.

The files in < tt > icudata.jar< / tt > get extracted to < tt > com/ibm/icu/impl/data< / tt >
in
2005-07-26 21:44:58 +00:00
the build directory when the 'core' target is built.
Building the < tt > 'resources'< / tt > target will force the
2004-11-09 23:35:01 +00:00
resources to once again be extracted. Extraction will
2004-06-15 22:59:13 +00:00
overwrite any corresponding resource files already in that directory.

< li > Change directory to < I > $icu4c_root< / I > /source/tools/genrb. < I > $icu4c_root< / I >
2008-05-02 23:46:07 +00:00
is the root directory of ICU4C source package.< / li >
< li > Run gendtjar.pl from that directory itself with the command < br >
< tt > ./gendtjar.pl --icu-root=< I > $icu4c_root< / I > --jar=< I > $jdk_home/bin< / I > --icu4j-root=< I > $icu4j_root< / I > < / tt > < br >
e.g. < br >
< tt > ./gendtjar.pl --icu-root=$HOME/icu4c --jar=/usr/local/bin/java/bin/ --icu4j-root=$HOME/icu4j< / tt > < br >
Execution of gendtjar.pl script will create the required jar files in
the $icu4c_root/source/tools/genrb/temp directory and then copy them to their
final locations in the ICU4J structure,
< tt > $icu4j_root/src/com/ibm/icu/impl/data< / tt > and < tt > $icu4j_root/src/com/ibm/icu/dev/data< / tt > .< / li >
< li > Build resources target of ant to unpack the jar files with the following commands: < br >
