Hi Patrick

Indeed, JSF 2.0 do not work out of the box with JOnAS 5.x.
JOnAS 5.x is Java EE 5 compliant and JSF 2 is part of Java EE 6.

Anyway, it's still possible to use JSF 2.0 withing JOnAS 5.x.
Here how to do that:

1. Ensure that your web.xml has the 'version' attribute set to 2.5 (JSF 
2 mandates Servlet 2.5)
2. Declares your Faces Servlet and maps *.jsf paths to it

   1.
      <servlet>
   2.
      <servlet-name>Faces Servlet</servlet-name>
   3.
      <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
   4.
      </servlet>
   5.
   6.
      <servlet-mapping>
   7.
      <servlet-name>Faces Servlet</servlet-name>
   8.
      <url-pattern>*.jsf</url-pattern>
   9.
      </servlet-mapping>


3. Also ensure that your faces-config.xml 'version' attribute is set to 
2.0 (See example of a minimum file below)

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
       http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
       version="2.0">
</faces-config>

4. You also have to tweak the ClassLoader to ensure that you will use 
the JSF API and implementation that you have in your webapp. This can be 
done using the WEB-INF/jonas-web.xml

<jonas-web-app xmlns="http://www.objectweb.org/jonas/ns"
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                xsi:schemaLocation="http://www.objectweb.org/jonas/ns
                http://www.objectweb.org/jonas/ns/jonas-web-app_4_0.xsd">
       <java2-delegation-model>false</java2-delegation-model>
</jonas-web-app>

4.b Note that you can achieve the same result by filtering javax.faces.* package using the conf/filtering-default-classloader.xml

5. Then your XHTML files should looks like:
<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:ui="http://java.sun.com/jsf/facelets">

6. Do not forget to embed the JSF 2.0 API+Implementation jars in your WEB-INF/lib


Notice that only the step #4 is specific to JOnAS.

Hope this helps....

Cheers
