< p > The International Components for Unicode (ICU) library provides

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

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.

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 available
2009-04-25 21:33:06 +00:00
in J2SE 5 or later releases. The binary distribution of ICU4J
jar file may have a problem with older JRE versions.
We provide the ability to build a variant of ICU4J for JRE 1.3
or 1.4. If you want to use ICU4J running on JRE 1.4, you should
build ICU4J libraries from the source package with JDK 1.4.
With older JDK releases, some build targets may not work.

If you want to use ICU4J (as opposed to developing it), your best bet
2008-06-30 18:08:59 +00:00
is to download an official, packaged version of the ICU4J library files.
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://www.icu-project.org/download/" > ICU Downloads page< / a > .

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

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 >
2009-04-25 21:33:06 +00:00
< li > Install J2SE SDK 6.0. (You can use any version of J2SE SDK 1.3 or newer,
but but J2SE SDK 5.0 is the minimum version 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 >
2009-04-25 21:33:06 +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
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 >
2009-04-25 21:33:06 +00:00
set JAVA_HOME=C:\jdk1.6.0
2007-08-30 23:51:41 +00:00
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 >

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).
2008-06-30 18:08:59 +00:00
The ICU4J resource information is equivalent to the information in ICU4C and
2007-08-04 02:07:57 +00:00
many resources are, in fact, the same binary files that ICU4C uses.
2002-08-15 17:39:50 +00:00
< p >
2004-06-15 22:59:13 +00:00
By default the ICU4J distribution includes all of the standard resource

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
from release to release, so clients should not depend on the exact

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 >

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
< code > java.util.ResourceBundle< / code > for more information.

< 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 > ).

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.

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.

< p > ICU4J 4.4M4 includes time zone data version 2010a, which is the latest one as of
2008-06-30 18:08:59 +00:00
the release date. However, time zone data is frequently updated in response
to changes made by local governments around the world. If you need to update
the time zone data, please refer the ICU user guide topic
< a href = "http://www.icu-project.org/userguide/dateTimezone.html#tzupdate" > Updating the Time Zone Data< / a > .< / p >
< p > Starting with ICU4J 4.0, you can optionally configure ICU4J date and time
service classes to use underlying JDK TimeZone implementation (see the ICU4J API reference
< a href = "http://www.icu-project.org/apiref/icu4j/com/ibm/icu/util/TimeZone.html" > TimeZone< / a >
for the details). When this configuration is enabled, ICU's own time zone data
won't be used and you have to get time zone data patches from the JRE vendor.< / p >
