The Localization Component is an efficient and flexible replacement of the old MessageTool class, which eases the deployment of XWiki applications.

Localization here refers to translation; see the Wikipedia article about internationalization and localization for more details. In summary, this Component allows applications and components (or any Java code in general) to be translated into different languages.


  • Efficient implementation by making intensive use of caching.
  • Pluggable Translation Bundle types, allowing developers to create and use new types of translations. At the moment Bundles defined in wiki documents (a.k.a. Document Translation Bundles) and in .properties files (File Translation Bundles) are supported.
  • Document Translation Bundles can be dynamically registered using Translation XObjects. This allows applications and Components to include their own translation documents without requiring additional configuration, and without bloating the main File Translation Bundle (found in
  • Powerful parameterized translations, as supported by the Java MessageFormat class.


Translation macro

You can insert a translation in a content using the translation macro as follow:

{{translation key="some.translation"/}}

See the Translation Macro documentation for more details.

From Velocity

See Localization Scripting.

From Java

Two main entry points (components) are available on Java side to manipulate translations:

import org.xwiki.localization.ContextualLocalizationManager;
import org.xwiki.localization.LocalizationManager;

public class MyComponent
 // For most use cases (simpler API, use the locale from the context, plain text output helper, etc.)
 private ContextualLocalizationManager contextLocalization;

 // Or if you need more control
 private LocalizationManager localization;


See Component Module if you need more details on how to lookup a component.

Register a wiki translation

It's possible to mark a document as a Document Resource Bundle by adding a XWiki.TranslationDocumentClass XObject to this document.

  • Scope:
    • GLOBAL: translation registered for the whole farm
    • WIKI: translation registered only for the document wiki
    • USER:  translation registered only for the document author

The content of this document is a list of key=value pairs, as in:

my.translation.key=Some translation message
my.other.translation.key=Some other translation message

Provide translation bundle in a jar

A jar (installed extension or core extension) can come with its own translations bundle. For that all is needed is to name it for the default language and ApplicationResources_<locale>.properties (for example for its translations and put them in the default package (i.e. root of your JAR). It will be automaticlally registered at startup for core extensions and when installed for installed extension (it will also be unregistered automatically if the jar extension is uninstalled).

Tested on

This extension has been tested with the following configurations.
