Richfaces 4 sem skin

Front-end
#1

Olá, segui os passos da documentação, porém não aparece as skins do richfaces.

Uso o tomcat 7 e já adicionei as libs jsf 2 api e impl, richfaces-core-api, richfaces-core-impl, richfaces-components-api, richfaces-components-ui, jstl, sac-1.3.jar, cssparser-0.9.5.jar, google-guava-r08.jar

Meu web.xml:

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>

Minha página cadastro-movimentacao.xhtml usa o componente rich:dataTable. Ele está sendo renderizado de acordo com a lógica do managedBean, mas sem a skin do rich:

						itemLabel="#{tipoMovimentacao}" />
				</h:selectOneMenu>
			</h:panelGrid>

			<h:outputLabel value="Digite uma descricao para pesquisa" />
			<h:inputText value="#{movimentacaoMB.descricao}" />
			<h:commandButton action="#{movimentacaoMB.pesquisaMovimentacoes}"
				value="Pesquisar" render="tabela_listaMovimentacoes">


			</h:commandButton>





			<rich:dataTable width="700"
				rendered="#{movimentacaoMB.movimentacoes != null}"
				value="#{movimentacaoMB.movimentacoes}" var="movimentacao"
				id="tabela_listaMovimentacoes" rows="5">
				<f:facet name="header">Lista de Movimentacoes</f:facet>
				<rich:column>
					<f:facet name="header">
						<h:outputText value="Valor" />
					</f:facet>
					<h:outputText id="valor" value="#{movimentacao.valor}" />
				</rich:column>
			</rich:dataTable>

		</h:form>
	</h:body>
</ui:composition>
</html>

Alguém já passou por isso ?
