As you've learned from the Programming feature it's possible to put code inside XWiki pages. You can combine several pages together to form an application. In other words an application is simply a self-contained set of XWiki pages. You can export these pages into a single archive file named a XAR (it stands for XWiki Archive) which can then be imported again into other wikis. This is a very nice way to create reusable applications.

Applications offer a powerful way to create advanced content within wiki pages.

List of Applications available for download on

Check the Extensions wiki which lists all applications available that you can install in your wiki.
