server_ip = (java.util.Hashtable)request.getAttribute("server_ip");

if (server_ip.size() > 0) {
enumHash = server_ip.elements();
while (enumHash.hasMoreElements()) {

If you want only unique values, you should be looking at the various Set classes in the collections API.

Please don't post the same question in multiple forums. We've been discussing your question here for several days -- if you don't like the answers you're getting, then you'll need to refine your question.

Note that Bill just gave you the same answer as you're already getting in the other thread, by the way.

I'm closing this thread; take this discussion back to the other one.
