not coming up

[Palat, Anil]

Hi,
 
Iam working with tomcat 5.0.28, Myfaces 1.1.5 & JDK1.4.2_14
 
When I run the following JSP Iam not getting the datatable displayed
though the text "Tomahawk table" is displayed. Please let me know
whether Iam missing anything.
Is it due to any version incompatibilities?
 
<[EMAIL PROTECTED] uri="http://java.sun.com/jsf/core"; prefix="f"%> 
<[EMAIL PROTECTED] uri="http://java.sun.com/jsf/html"; prefix="h"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk"; prefix="t"%>
 
   <f:view>
       <t:outputText value="Tomahawk table"/>
       <t:dataTable var="mapper" value="#{selectMappingBean.mappings}">
           <h:column>
               <f:facet name="one">
                   <t:outputText value="Manager Name"/>
               </f:facet>
               <t:outputText value="#{mapper.managerName}"/>
           </h:column> 
       </t:dataTable>
   </f:view>
 
 thanks
