Struts if tag doesn't work

I'm trying to use the Struts tag if

with an iterator, but it doesn't work. Here is the code for that

<s:iterator status="i" value="pages" >
   <s:set var="kk" value="<s:property />" />     

   <s:if test="%{(#kk<5)}">
      Hello
   </s:if><s:else>
      Hi
   </s:else>                        
</s:iterator>

A list pages

is a list of integers. The above code should print Hello

if the value is pages

less than 5, but print it for all values pages

.

There are so many options out there with OGNL, jstl, etc. that it can be a nightmare to get the value. Try with this, I think the following case %{}

is optional



<s:iterator id="page" value="pages">
   <s:if test="#page < 5">Hello</s:if> <!-- or <s:if test="%{#page < 5}"> -->
   <s:else>Hi</s:else>
</s:iterator>

Must use

<s:set name="kk"  value="0" />

instead



<s:set var="kk"  value="<s:property />" />

and you shouldn't use the tag <s:

in the struts tag attribute

<s:set name="kk" value="0"/>
<s:iterator status="i" value="bloglist" >
  <s:set name="kk"  value="%{#kk+1}" />
  <s:if test="%{(#kk<2)}">
    Hello<br>
  </s:if>
  <s:else>
  Hi<br>
</s:else>
</s:iterator>

You don't even need to use <s:set>

.

Just make full use of the power Iterator

:

 <s:iterator var="itr" status="ctr" value="pages" >    
    <s:if test="%{itr[#ctr] < 5}">
       Hello
    </s:if><s:else>
       Hi
    </s:else>    
 </s:iterator>
