Configuring Java Component locale using localemap.xml
Open <context root>\WEB-INF\localemap.xml to see a listing of the available locales in Java Component. Add locales to this file by following the exact format of the existing locales. To see each locale defined in the file, search for one of the following strings:
<Locale
or:
<DisplayName>
Searching for <Locale places the mouse pointer on the line with the ID for the locale. Searching for <DisplayName> places the mouse pointer on the line with the descriptive name for the locale.
In general, the locale names have the following syntax:
<language>_<country>
For example, ar_EG is Arabic (Egypt). When a single language is spoken in multiple countries, the language remains the same and the country can have several values. For example, en_US is the locale for English (United States) while en_AU is the locale for English (Australia). en_BZ is the locale for English (Belize). Some countries can have several locales, one for each language. For example, Canada has both en_CA for English (Canada) and fr_CA for French (Canada).
You specify a default locale for a custom web application in <context root>\WEB-INF\web.xml.
