I have done a couple projects using JSF and facelets, but it has been awhile since I set up a new one from scratch. I think I have all the pieces in place but the facelet will not render. Can anyone tell me what I am missing? The last piece of code is the resulting HTML page. The <application:signIn></application:signIn> line is where the facelet is supposed to render, but some link must be missing.

Thank you in advance!
Jon

I found my problem, or problems. The funny thing is now I'm not sure how my current projects are working!

First problem was my taglib.xml couldn't be found. I simply had it in the wrong folder. Once I moved it to the correct place I got past the rendering problem.

Then I got the following error:
javax.servlet.ServletException: PWC1232: Exceeded maximum depth for nested request dispatches: 20

After researching this awhile I found that I didn't have things configured right.

First, in my faces-config.xml I needed to change my opening tag and comment out the view-handler:
XML: 
<?xml version="1.0" encoding="UTF-8"?>
<faces-config 
   xmlns="[URL unfurl="true"]http://java.sun.com/xml/ns/javaee"[/URL]  
   xmlns:xsi="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema-instance"[/URL]  
   xsi:schemaLocation="[URL unfurl="true"]http://java.sun.com/xml/ns/javaee[/URL] [URL unfurl="true"]http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"[/URL] 
   version="2.0">
	
	<!-- 
	<application>
    	<locale-config>
    	  <default-locale>en</default-locale>
	    </locale-config>
		<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
	</application>
	-->

Then in my web.xml I needed to change my default suffix to .xhtml
XML: 
  <context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.xhtml</param-value>
  </context-param>

And finally I had to rename my main page signIn.jsf to signIn.xhtml. Then viola, it worked!!
