In this example I'll add a parameter to a facelets template. The example contains three tabs, each tab points to a different page. The tab control is shared among all pages, therefore, it is put in the template. Starting from the simple facelet example , make these additions: Create a new template WEB-INF/templates/tabs.xhtml :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric...Add a page for the about tab ( about.xhtml ):

This is a simple example to demonstrate the templating power of JSF facelets. If you've used struts tiles before, you'll recognize the simplicity of templating with facelets. I've stripped out everything else except the pages themselves, just to put our focus on facelets. This is a Maven based project, and you need Tomcat (or any servlet container) to run the resulting webapp. To begin with this is the list of files:
./pom.xml ./src/main/webapp/home.xhtml ./src...I left faces-config.xml in there for completeness sake, it may not be needed. The Maven POM ( pom.xml ):

I have long noticed that IE8 displays a "broken page" icon while showing my web pages, but didn't pay much attention. Since the world in general considers IE to be broken, it's not so unlogical for IE to see much of the world as broken. Until one day I noticed that the Google home page was not "broken". Then I thought may be I should fix my pages also. So I moused over the "broken page" icon, and this is what I saw: Compatibility View: websites designed for older browsers will often look better, and problems such as out-of-place menus, images, or text will be corrected. Very descriptive indeed! Older browsers? Such as Firefox 1.5? When it comes to MS products, I often had better...
