How to know if List is empty or not in Struts2?

list, struts2

Solution

You can use Struts2 `<s:if>` and `<s:else>` tags for conditional checking like this:

<s:if test="%{getProductList().isEmpty()}">
   Error
</s:if>
<s:else>
     <s:iterator value="productList">
        <tr style="background-color: #99CCFF">      
            <td><s:property value="pid"/></td>
            <td><s:property value="productname"/></td>
            <td><s:property value="producttype"/></td>
            <td><s:property value="productprice"/></td>
            <td><s:property value="shopname"/></td>
            <td><s:property value="productcity"/></td>
            <td><s:property alue="ownername"/></td>                 
        </tr>
    </s:iterator> 
</s:else>
