5 1.1 Using the static Resource Bundles
6
7 * Stop your XWiki instance
8 * Unjar the <tt>WEB-INF/lib/xwiki-core-\*.jar</tt> file (it was named <tt>xwiki.jar</tt> in old versions) in <tt>WEB-INF/classes</tt> and remove it from <tt>WEB-INF/lib</tt>
9 * Edit the <tt>WEB-INF/classes/ApplicationResources*.properties</tt> Resource Bundle files by adding the key/value pairs you need for your application.
10 * In your document, use the following to get the value associated with a key:
11
12 {code}
13 $msg.get("key")
14 {code}
15
16 This will get the value from the Resource Bundle corresponding to the current language you are using in XWiki.
17
18 1.1 Using properties located in XWiki pages
19
20 #warning("The features described below are only available in XWiki 1.0 Beta 4 and above. The ability to parametrize the resource string is available only in XWiki 1.0 Beta 5 and above.")
21
22 * Create a page that will host your key/value pairs.
23 * Enter all the key/value pairs in that page (use the wiki editor). For example:
24
25 {code}
26 greeting=hello
27 welcome=Welcome
28 withparams=I can {0} pass {1} {2} params too using the Java MessageFormat syntax
29 {code}
30
31 * Do the same for all the translations you want.
32
33 #info("To enable multiple languages you'll need to go to the Administration page and set MultiLingual to true and list the different languages you wish to use in the Languages field.")
34
35 * Tell XWiki that your page is a Document Bundle by going to the Administration page, selecting the "Programming" icon and entering it in the "Internationalization Document Bundles" field. You can specify several pages, separated by commas.
36
37 #info("When creating \"Internationalization Document Bundles\", you should avoid naming the pages with names that include spaces. For example, a document name of Main.My Messages could cause issues, instead, use Main.MyMessages")
38
39 * Alternatively you can also specify the list of Internationalization Document Bundles in <tt>xwiki.cfg</tt> under the key <tt>xwiki.documentBundles</tt>.
40
41 * On the page where you want to use the internationalized message, use:
42
43 {code}
44 $msg.get("key")
45 $msg.get("key", ["param1", "param2", ...])
46 {code}
47
48 where <tt>key</tt> is the key for the message to retrieve. Parameters can also be passed as is shown in the second syntax above.

50 1.1 I18n of XWiki Objects
51
52 This is currently not implemented (see our logged issue: [XWIKI-69>http://jira.xwiki.org/jira/browse/XWIKI-69]). There are 2 workarounds you can use:
53 * Have several objects, one for each language, with a language field, and then decide which object to use (for example in a Class Sheet, based on the current language).
54 * Use Velocity scripting to do an IF in your object. For example, you could have:
55 {code:none}
56 #if ($context.language == "fr")
57 French texts
58 #else
59 Default texts
60 #end
61 {code}
