Erro na JSP quando tenta "zebrar" uma tabela usando JSTL

Boa tarde amigos,

Estou tentando zebrar uma tabela no JSP usando JSTL, mas está apresentando erro. Segui o exemplo que achei aqui no forum mas não funfa. Lembrando que sem tentar zebrar, funfa sem problemas. O que pode ser amigos?

Exemplo:

<table>  
     <c:forEach items="${suaLista}" var="linha" varStatus="i">  
         <c:choose>  
             <c:when test="${i.count % 2 == 0}">  
                 <tr bgColor="#CC0000"> <%-- Use styles... fica melhor... --%>  
             </c:when>  
             <c:otherwise>  
                 <tr bgColor="#0000CC">  
             </c:otherwise>  
   
             <td>${linha.atributo1}</td>  
             <td>${linha.atributo2}</td>  
             <td>${linha.atributo3}</td>  
   
             </tr> 
   
         </c:choose>  
     </c:forEach>  
 </table>

Minha JSP:

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt"%>

<table>
	<c:forEach items="${lFornecedor}" var="fornecedor" varStatus="i">
			<c:choose>
             		<c:when test="${i.count % 2 == 0}">  
				<tr bgColor="#CC0000">
			</c:when>
				<c:otherwise> 
					<tr bgColor="#0000CC">
				</c:otherwise>
					<td>${fornecedor.razaoSocial}</td> 				
				        <td>${fornecedor.cnpj}</td>
			    </tr>
			  </c:choose>
	</c:forEach>
</table>

Erro:

Tente mover o para a linha 16:

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt"%>

<table>
	<c:forEach items="${lFornecedor}" var="fornecedor" varStatus="i">
			<c:choose>
             		<c:when test="${i.count % 2 == 0}">  
				<tr bgColor="#CC0000">
			</c:when>
				<c:otherwise> 
					<tr bgColor="#0000CC">
				</c:otherwise>
			  </c:choose>
					<td>${fornecedor.razaoSocial}</td> 				
				        <td>${fornecedor.cnpj}</td>
			    </tr>

	</c:forEach>
</table>

Pela mensagem de erro, ele não estava esperando nada além das tags c:when e c:otherwise dentro do c:choose.
