Primefaces tag library on tomcat, rendering an empty page from a valid jsp file

Question

I've posted here earlier about how to make a tic tac toe for two users using jsf and I got the link for this great taglib, Primefaces. It's absolutely perfect for what I need to do, but I'm being stuck on trying to make it do anything, even render the examples from their website.

So I've been following this tutorial I found (sadly, there aren't many of them on the subject of Primefaces): http://java.dzone.com/articles/primefaces-quickstart-tutorial Step by step, I made everything according to this tutorial, yet when I run it, it renders an empty page every time.

So I tried a simpler example from the official website: http://www.primefaces.org/gettingStarted.html

This (test.xhtml):

 <html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">
    <h:head>
    </h:head>   
<h:body>    
<p:spinner />   
</h:body>
</html>

renders an empty page, while this:

 <html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">
    <h:head>
    </h:head>   
<h:body>
test test test test
<p:spinner />   
</h:body>
</html>

renders only the "test test test test" text.

So I guess the problem must be in the tags, tomcat doesn't see them/doesn't know how to interprete them. But, according to the tutorial and the primefaces website all I need to do is to put the jars in WEB-INF/lib as I have done (by the way, I'm using Eclipse and the empty project I created was "Dynamic Web Project"). In my WEB-INF/lib I have the following jars:

jsf-api-2.0.3.jar

jsf-impl-2.0.3.jar

jstl-1.0.2.jar

primefaces-3.3.RC1.jar

If it's of any help, here's the content of the tomcat console:

    2012-05-27 13:18:17 org.apache.catalina.startup.Catalina start
    INFO: Server startup in 5096 ms

What can be the case? Am I putting the jars in wrong place, is it a tomcat failure or maybe something else entirely?

Ok, I solved it, maybe someone will someday find this useful.

So, when using Primefaces with JSF, not only the webpage files have to have the .xhtml extension (a solution I've found here: http://www.coderanch.com/t/473437/JSF/java/not-allowed-template-text), but also the web.xml file must be modified (a solution I've found here: Simple primefaces application not working), like this:

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

Now it works perfectly well.

This problem is not strictly related to PrimeFaces, but to basic JSF in general. You would have exactly the same problem when not using PrimeFaces. Rightclick page in browser, *View Source*, you'll see that standard JSF tags like `` and so on are **also** unparsed when the request did not invoke the `FacesServlet`! – BalusC May 27 '12 at 17:30
