Testa assim:

<%@page contentType="text/html" pageEncoding="UTF-8"%> 

<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%> 
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

                    </h:column>

            </h:form>

    </body> 
</html>

Se não funcionar vê se a a variável 'code' está escrita corretamente.
