Struts if tag with iterator tag is not working

I am trying to use Struts if tag with iterator but it is not working.

Here is the code for this:

<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>

The pages list is a list of integers.

The above code should print Hello if pages value is less than 5 but print it for all values of pages.

You do not even need to use <s:set>.

Just fully exploit the Iterator power:

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

Should use 

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

instead of 

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

and you should not use <s: tag in the attribute of struts tags

<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>

There's so many options with OGNL, jstl and so on that it can become a nightmare to retrieve a value. Try with this one, I think in the following case the %{} is not mandatory

<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>
