Myfaces Tomahawk for JSF

Pessoal

Alguém sabe me dizer como configurar o web.xml no netbeans para funcionar com o Myfaces Tomahawk ?

Fiz da seguinte forma

No netbeans criei um projeto web com suporte a jsf.

no web.xml

adicionei o seguinte:

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

<!-- extension mapping for adding <script/>, <link/>, 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>/*.jsp</url-pattern>
</filter-mapping>

fonte http://myfaces.apache.org/tomahawk/extensionsFilter.html

e no arquivo jsp

<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>

Mas ele fica dando uma mensagem no jsp dizendo que não conseguiu resolver a url na linha deste taglib…

obs.: Importei os jar.

Obrigado,
