Re: [icu-support] [icu_support]how to customize the data for icu4j?

[Ram V. <ram...@gm...>]

ICU4J 3.4 is based on Unicode 4.1. If you create data for Unicode 4.0 and
add it to ICU4J, please be warned that some APIs will behave differently.

yes. Please see
http://source.icu-project.org/repos/icu/icu4j/tags/release-3-4/readme.html#resources
the
section "Building ICU4J Resources from ICU4C"

just like the icudata.jar within the source code of icu4j.


ICU4J data depends on ICU4C. So you need to build ICU4C data and convert
that to ICU4J format.

Could you

icudata.jar is generated by icu/source/tools/genrb/gendtjar.pl.
