I know, the docs can be a little intimidating.
Here's (more or less) what you've provided us:
<logic:iterate id="thread" name="page_of_results" indexId="index">
<bean:define id="hot_topic" name="hot_topic" value="false" />
<logic:greaterThan name="thread" property="replyCount" value="100">
<bean:define id="hot_topic" name="hot_topic" value="true"/>
</logic:greaterThan>
<logic:equal name="hot_topic" value="true">
<img src="/midletsite/images/hot_topic.gif"/>
</logic:equal>
</logic:iterate>
From this I am assuming:
- You are iterating over a collection of beans.
(I'll call them TopicBeans for now.)
- You've placed this collection in the request (or some scope) under the name
"page_of_results".
Now you want to know if the number of replies to that thread are greater than
100 (thread.getReplyCount() > 100)
If so, then show the "hot_topic.gif" icon.
Am I on target so far?
If so, first thing I would do is pull that logic out of the tags. Hell, pull
it out of the page altogether. Make this configurable via the bundle. Add a
boolean to your bean isHotTopic. In your action, check to see if the number
of threads is greater than 100 (or some parsed value from your properties
file).
So you should be able to do this:
<logic:iterate id="thread" name="page_of_results" indexId="index">
<logic:equal name="thread" property="hotTopic" value="true">
<html:img page="/images/hot_topic.gif"/>
</logic:equal>
</logic:iterate>

BTW. I also fixed your image tag, you should never hard-code your
application's context in your pages.
