Internationalization with Resource Bundles

Internationalizing Content

Components can be used on different websites and countries. In those cases, Content can be internationalized so that it is displayed in different ways depending on the region.

To enable the internationalization of contributed content, each individual component property can have the feature enabled.

Editing in Jahia Studio

Note the Internationalized option is checked off.

Editing with a Text Editor or IDE

The i18n or internationalized keyword can be appended to the property definition.

Note the following example for a property title:

[mynt:myComponent] > jnt:content, jmix:structuredContent
 - title (string)

The resulting internationalization becomes either:

 - title (string) i18n

or

 - title (string) internationalized

Note that the i18n and internationalized keywords achieve the same result. Both enable internationalization for the given property.

As a result of this change, content of type mynt:myComponent has a language dependent title value.

Internationalizing Properties

In addition to Content, the Edit window UI labels corresponding to defined components may also be internationalized.

This is useful in cases where a multilingual editing team is a working on the same project. 

Editing in Jahia Studio

The Resource Bundle files can be found in /resources/resources.

Right-clicking Edit on one of the available [moduleName]_[lang].properties files opens the Studio Resource Bundle Editor for the corresponding file:

Selecting the generic [moduleName].properties enables editing the labels for each available language:

Editing in a Text Editor or IDE

For example, editing the English label title for mynt:myComponent :

1. Open the file at /resources/resource/{module_name}.en.properties
2. Add mynt_myComponent.title as the key
3. Set the desired value

Example Result:

mynt_myComponent.title=desired value

Internationalizing Static Values

In views, there is sometimes a need to display static values such as labels or messages.

Despite being static, those values can be internationalized according to the the visitor browsing language.

In views, values should not be hardcoded. Instead, a label can be referenced:

1. Declare a new property in the[module_name].properties file:

   [unique_prefix].[label_name]=[desired_label_value]

   [unique_prefix] enables a unique identifier for label_name. This is particularly useful when properites with the same label_name are referenced in several properties files.

2. Reference the property value to be displayed in the view using the fmt:message function:

   <%@ taglib prefix="fmt” uri="http://java.sun.com/jsp/jstl/fmt" %>
   <fmt:message key="propertyKey"/>

Displaying a warning message to Editors:

1. Declare the given property in the properties file: myComponent.emptyEditorWarningMessage. 
2. Reference the property value to be displayed in the view:

   <%@ taglib prefix="fmt” uri="http://java.sun.com/jsp/jstl/fmt" %>
   <fmt:message key="myComponent.emptyEditorWarningMessage"/>

Exercise: Internationalizing a Component Property

Part I - Internationalize the Employee Biography Property

1. In the definitions.cnd, internationalize the Biography field
2. Enter the values for the property in several languages. The Resource Bundle Editor, can be useful here.
3. Check the result in preview mode for each language for which biography was given a value.

Part II - Internationalize the Employee Property Label

To edit the English employee property label:

1. Open the file at /resources/resources/[module_name]_en.properties.
2. Add mynt_employee.jcr_title as the key.
3. Set the desired value.

Then, repeat these steps for another language and verify the results in Edit Mode.
