I am new to JSF's and using JBoss 4.2.0 application server.

I trying to use <t:panelTabbedPane> and <t:panelTab> in my page like this:

<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>
<t:panelTabbedPane id= "tbParticipant" selectedIndex = "0">
<t:panelTab id = "ptFirstName" label = "First Name"></t:panelTab>
<t:panelTab id = "ptLastName" label = "Last Name"></t:panelTab>
</t:panelTabbedPane>

When I open my page i get this error

ExtensionsFilter not correctly configured. JSF mapping missing. JSF pages not covered.
Please see: http://myfaces.apache.org/tomahawk/extensionsFilter.html

I have my web.xml configured exactlly as described at http://myfaces.apache.org/tomahawk/extensionsFilter.html
Actually I copied and paste the whole text word by word as shown below but still getting that error.


<filter-name>MyFacesExtensionsFilter</filter-name>
<filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
<init-param>
<param-name>maxFileSize</param-name>
<param-value>20m</param-value>
Set the size limit for uploaded files.
Format: 10 - 10 bytes
10k - 10 KB
10m - 10 MB
1g - 1 GB

</init-param>


<!-- extension mapping for adding , , and other resource tags to JSF-pages -->
<filter-mapping>
<filter-name>MyFacesExtensionsFilter</filter-name>
<!-- servlet-name must match the name of your javax.faces.webapp.FacesServlet entry -->
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

<!-- extension mapping for serving page-independent resources (javascript, stylesheets, images, etc.) -->
<filter-mapping>
<filter-name>MyFacesExtensionsFilter</filter-name>
<url-pattern>/faces/myFacesExtensionResource/*</url-pattern>
</filter-mapping>
Alternate mapping using a url-pattern instead of a servlet-name (you still need the /faces/myFacesExtensionResource/* mapping as well):
<!-- extension mapping for adding , , and other resource tags to JSF-pages -->
<filter-mapping>
<filter-name>MyFacesExtensionsFilter</filter-name>
<url-pattern>*.jsf</url-pattern>
</filter-mapping>

Please help and thank you in advance.
