ResourceBundle in Google App Engine Servlet does not work as expected

问题

Can someone help me to understand why internationalization using ResourceBundle does not work in Google App Engine Servlet the same way it works in a command line Java application?

The following snippet:

ResourceBundle resource_en_US, resource_de_DE, resource_ja_JP;

resource_en_US = ResourceBundle.getBundle(bundleBasename, Locale.US); resource_de_DE = ResourceBundle.getBundle(bundleBasename, new Locale("de_DE")); resource_ja_JP = ResourceBundle.getBundle(bundleBasename, new Locale("ja_JP"));

logger.info("resource_en_US:" + resource_en_US.getLocale()); logger.info("resource_de_DE:" + resource_de_DE.getLocale()); logger.info("resource_ja_JP:" + resource_ja_JP.getLocale());

Logs only en_US in GAE.

resource_en_US:en_US

resource_de_DE:en_US

resource_ja_JP:en_US

But logs the appropriate Locales in command line Java program.

resource_en_US:en_US

resource_de_DE:de_DE

resource_ja_JP:ja_JP

Make sure your properties files are being copied into WEB-INF/classes. You can check this out using a command shell.
