The derby.ui.locale property specifies an alternative supported locale name when you use one of the Derby tools with a language not supported by your default system.
The locale determines the localized display format for numbers, dates, times, and timestamps, as well as the language of the messages from the Derby tools.
This property is commonly used in conjunction with the derby.ui.codeset property.
derby.ui.locale=derbyval
where derbyval is a supported locale name, in the form ll_CC, where ll is the two-letter language code, and CC is the two-letter country code; for example, ja_JP.
The following command runs ij using the Japanese locale (derby.ui.locale=ja_JP) and Japanese Latin Kanji mixed encoding (derby.ui.codeset=Cp939):
java -Dderby.ui.locale=ja_JP -Dderby.ui.codeset=Cp939 \ -Dij.protocol=jdbc:derby: org.apache.derby.tools.ij
