# Messages libraries

The following list describes the items required in order for Derby to provide localized messages.

- You must have the locale-specific Derby jar file. Derby provides such jars for only some locales. You will find the locale jar files in the /lib directory in your Derby installation.
- The locale-specific Derby jar file must be in the classpath.

The locale-specific Derby jar file is named derbyLocale_ll_CC.jar, where ll is the two-letter code for language, and CC is the two-letter code for country. For example, the name of the jar file for error messages for the German locale is `derbyLocale_de_DE.jar.`

Derby supports the following locales:

- derbyLocale_cs.jar - Czech
- derbyLocale_de_DE.jar - German
- derbyLocale_es.jar - Spanish
- derbyLocale_fr.jar - French
- derbyLocale_hu.jar - Hungarian
