java jstl 用法？出异常了

<table width="100%" class="statusDataTable">

                          	<c:forEach var="i" begin="0" end="10" step="1"  >

                          		<c:choose>

     								 <c:when test="${i}%2==0">// <c:when test="${i%2==0}">这样写也不行

       									<tr bgcolor="#FFFFFF">

                                  			<td>${i}</td>

                               			</tr>

      								</c:when>

     						 		<c:otherwise>

       									<tr bgcolor="#E1DEDD">

                                  			<td>${i}</td>

                               			</tr>

      								</c:otherwise>

								</c:choose>

                          </c:forEach>

                  </table>

According to TLD or attribute directive in tag file, attribute test does not accept any expressions
