Using a deployed (but not running) showcase application... * replace sparkle-comps.jar for the one included in this zip file * replace calendar.xhtml for the one include din this zip file * copy skin-sprite.css and skin-sprite.png to the application's root directory (same directory as calendar.xhtml) Start the server and access http://localhost:8080/test/calendar.jsf to see that both the left and right arrows have changed to red, and hovering over a day changes its background to red, as well. Try editing the deployed calendar.xhtml file and removing (at the bottom). Then, when accessing the page again, the calendar will look normal. Note: it might be necessary to shift-reload the page sometimes.
