Struts2: comparing 2 variable in If tag not working

Question

I am retrieving 2 values (user id and profile id) and I've set them in the variable userId and profileId as shown below.

<s:set name="userId" value="#session.User.id"/>
<s:set name="profileId" value="%{#parameters['id']}"/>

<s:if test="%{#userId} != %{#profileId}" >

<a href="#" title="Follow" id="follow-btn">
<img src="theme/images/follow.png" alt="like" />
<span>Follow</span>
</a>

</s:if>

I have tested by using <s:property value="%{#userId}" /> and <s:property value="%{#profileId}" /> and both of them is able to display out the value. However I just can't get it to work in the if tag. Right now, the link button will never display no matter what's the value in those 2 variable.

I'm not sure if the if tag statement is right however I have tried a lot of combination (playing around with the %{} and ' ')

I have a feeling it has something to do with the data type but no matter what I did, the comparison expression just doesn't seem to be working..

Cheers!~

UPDATE: okay I've found out that the problem is in #profileId. Probably because the value is from #parameters['id'] which returns a String value. Is there any way to convert this value to int? I've tried Integer.parseInt(#profileId) but that doesn't work.

Try using this:

<s:if test="#userId != #profileId" >
