HTTP Session replication problem

Question

Hi all,
After 3 days trying to make the http session replication work in my cluster is time to ask some help.
I´m trying to make a simple application (only a servlet) simulate a http session replication.
I´ve investigated all the possible problems that i encountered in google :
Here is my multicast tests :
SERVER 1
D:\>java -cp d:\bea\weblogic92\server\lib\weblogic.jar utils.MulticastTest -N SE
RVER1 -A 237.0.0.1 -p 12809
***** WARNING ***** WARNING ***** WARNING *****
Do NOT use the same multicast address as a running WLS cluster.
Starting test. Hit any key to abort
Using multicast address 237.0.0.1:12809
Will send messages under the name SERVER1 every 2 seconds
Will print warning every 600 seconds if no messages are received

Weblogic.XML descriptor
<session-descriptor>
          <session-param>
               <param-name>PersistentStoreType</param-name>
               <param-value>replicated</param-value>
          </session-param>
</session-descriptor>
CODE of the Servlet
HttpSession session = request.getSession();
          String sessionIdentif = (String)session.getAttribute("SESSIONIDENTIF");
          boolean boolNewSession = true;
          if(sessionIdentif == null) {
               session.setAttribute("SESSIONIDENTIF", "1234567890");
          } else
               boolNewSession = false;
As you can see the object that i put in session is a String, so Serializable....
All the requirements are validated (i think...) but it still not working ... i get the SESSION ID : WvHQMKzBh9T35BPhGJxyhQtGks5Q3qJmxnJwGn8mn7V24FM92cnh!949557342! NONE !1284141857480
And the NONE said that the session isn´t replicated.
Any idea what´s wrong with my try of getting http session replication working??
cheers,

Hi,
Thanks for your help.
I´ve tried your application with your proxy application but still no work...
I´m getting :
####<13/Set/2010 15H59m BST> <Debug> <Replication> <DST01VS51> <VIACTT2> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <> <1284389948055> <000000> <Creating primary 1678977133045201960>

In my early post i forgot to mention that i´m using an Apache 2.2 in the front-end with Weblogic 9.2 (cluster).
What is happening in this weblogic configuration so that this session replication don´t work.
cheers,
