struts2 question

[Raj Bhandari]

Hi all,
I want to find out the size of a results list so I can display correct message.
In Struts 1.x, I'd do this:

    
<bean:size id="size" name="xyzForm" property="resultList"/>
 
<logic:equal name="size" value="0">
<center><FONT color="red"><b>No Results Found</b></FONT></center>
</logic:equal>
 
<logic:greaterThan name="size" value="0">
       //begin iteration
</logic:greaterThan>

But how do I do the same using Struts2 ? Is there a way now without JSTL tags for this?

Tks :-)

I'd suggest just using JSTL:

<c:choose>
  <c:when test="${empty resultList}" >
    <!-- do something -->
  </c:when><c:otherwise>
    <!-- do something else -->
  </c:otherwise>
</c:choose>

Tks Merrill, I knew one option is jstl or we could do this:

    
<s:if test="%{resultList!=null}">
  Search Results: <br><br>

  <s:if test="%{resultList.isEmpty}">
     No results found
  </s:if>
  <s:else>
     //iterate thro's list
  </s:else>
</s:if>

Hopefully, it helps someone..
