结果集为空时，无法在JSP中显示空白字段值

Question

我有一个PRODUCT字段，它在JSP中有两个字段（SELECTED＆TOTAL COST）。 如果产品不是EMPTY，但我可以检索字段名称和值 产品为空时，无法将字段值（SELECTED＆TOTAL COST）显示为空白。  根据要求，这两个字段值如果为空，则应显示为空白。

我使用，但是它循环了多次， 它不会显示空白字段

实际代码：

<tr>
                <td class="panelLabel" style="text-decoration: underline;">PRODUCT:</td>
                <td class="panelValue"></td>
            </tr>
            <c:forEach items="${applicationDetails.application.product}" var="product">
            <c:if test="${not empty product and (fn:toUpperCase(product.isPlanSelected) eq 'Y')}">
            <c:set var="isAtleastOneSelected" value="yes"></c:set>
            <tr>
                <td class="panelLabel">SELECTED: &nbsp</td>
                <td class="panelValue"><c:out value="${product.isPlanSelected}"/></td>
            </tr>       
            <tr>
                <td class="panelLabel">TOTAL COST: &nbsp</td>
                <td class="panelValue"><fmt:formatNumber type="currency" value="${product.totalCost}"/></td>
            </tr>
            </c:if>
            </c:forEach>

我尝试过的代码：

<tr>
                <td class="panelLabel" style="text-decoration: underline;">PRODUCT:</td>
                <td class="panelValue"></td>
            </tr>
            <c:forEach items="${applicationDetails.application.product}" var="product">
            <c:choose>
            <c:when test="${not empty product and (fn:toUpperCase(product.isPlanSelected) eq 'Y')}">

            <c:set var="isAtleastOneSelected" value="yes"></c:set>
            <tr>
                <td class="panelLabel">SELECTED: &nbsp</td>
                <td class="panelValue"><c:out value="${product.isPlanSelected}"/></td>
            </tr>       
            <tr>
                <td class="panelLabel">TOTAL COST: &nbsp</td>
                <td class="panelValue"><fmt:formatNumber type="currency" value="${product.totalCost}"/></td>
            </tr>

            </c:when>
            <c:otherwise>

            <tr>
                <td class="panelLabel">SELECTED: &nbsp</td>
                <td class="panelValue"></td>
            </tr>       
            <tr>
                <td class="panelLabel">TOTAL COST: &nbsp</td>
                <td class="panelValue"></td>
            </tr>

            </c:otherwise>
            </c:choose>
            </c:forEach>
