Localization
...
Localization (aka L10n) is all about getting the right text to the user, in the right language.

Localization support is well integrated into Tapestry. Tapestry allows you to easily separate the text you present to your users from the rest of your application ... pull it out of your Java code and even out of your component templates. You can then translate your messages into other languages and let Tapestry put everything together.
...
Individual pages and components can override the values defined in the message catalog.

{note:title=Avoid BOMs}
Make sure that your properties files don't contain [byte order marks (BOM)|http://en.wikipedia.org/wiki/Byte_order_mark], because Java -- and thus Tapestry -- doesn't support BOM in properties files (see Make sure that your properties files don't contain byte order marks (BOM), because Java – and thus Tapestry – doesn't support BOM in properties files (see http://bugs.sun.com/view_bug.do?bug_id=4508058). Some editors write them out when saving a file in UTF-8, so watch out. {note} {float} |
Properties File Charset
Tapestry uses the UTF-8 character set (charset) when reading the properties files in a message catalog. This means that you don't have to use the Java native2ascii tool.
...
If you change a property file in a message catalog, you'll see the change immediately, just as with component classes and component templates (provided you're not running in production mode).
Asset Localization
When injecting assets, the injected asset will be localized as well. A search for the closest match for the active locale is made, and the final Asset will reflect that.
...
The PersistentLocale service can be used to programmatically override the locale. Note: You should be careful to only set the persistent locale to a supported locale.
