Translating the Pentaho Administration Console and Pentaho Enterprise Console
Both the Pentaho Enterprise Console and the Pentaho Administration Console use a message bundle called PacLocalizedMessages.properties which contains all of the text content common to each console. The default language is English, but translated message bundles for the following languages are also shipped with both PEC and PAC:
The instructions differ slightly between PAC and PEC because of JAR name differences and extra features in PEC. Follow the directions below for the console you are using (PEC for Enterprise Edition, and PAC for Community Edition).
Pentaho Administration Console
If you would like to make a message bundle for another language, check out the pentaho-open-admin-console project, and edit the /org/pentaho/pac/client/i18n/PacLocalizedMessages.properties file in it. Create a translated copy of that message bundle, appending the ISO language code appropriately. Rebuild the application when the new bundle is ready. You cannot drop the message bundle directly into the compiled JAR.
For a Japanese translation, you would create a file called PacLocalizedMessages_ja.properties. Search Google if you do not know what your two-letter ISO language code is. Two-letter country codes are also supported, so you can have a PacLocalizedMessages_fr_CA.properties for a French Canadian locale.
Pentaho Enterprise Console
If you would like to create a message bundle for another language, create a translated copy of the default PacLocalizedMessages.properties file found inside of the pentaho-open-admin-console-3.0.0-GA.jar file, appending the ISO language code appropriately. The exact path to the file is /pentaho/server/admin-console/lib/pentaho-open-admin-console-3.0.0-GA.jar/org/pentaho/pac/client/i18n/PacLocalizedMessages.properties
PEC contains an extra set of functions that have a separate message bundle inside the pentaho-bi-platform-engine-core-3.0.0-GA.jar file. The exact location of the extra message bundle is: /pentaho/server/enterprise-console/lib/pentaho-bi-platform-engine-core-3.0.0-GA.jar/org/pentaho/platform/engine/core/messages/messages.properties
The JARs will have to be unpacked with an archive utility before you can edit files inside of them. Once you have the modified properties files, contact your Pentaho support representative and ask to have an engineer rebuild the application with the new message bundles. You cannot drop the message bundles directly into the compiled JARs.
For a Japanese translation, you would create files called PacLocalizedMessages_ja.properties and messages_ja.properties. Search Google if you do not know what your two-letter ISO language code is. Two-letter country codes are also supported, so you can have a PacLocalizedMessages_fr_CA.properties for a French Canadian locale.
