RMI call To a specific EJB in a cluster ignored!!!

Question

I have an enumeration of objects in a cluster.
A specific problem is to reset some cash on every instance of a BEAN on all servers in a cluster.
Code below works fine when I start 2 instances of servers not in a clustered mode:
URL1=t3://pbwebs01:9466
and
URL2=t3://pbwebs02:9466
from t3://pbwebs01:9466 EJB instance -> call method resetCash() on t3://pbwebs02:9466 EJB instance
result:--> resetCash() on t3://pbwebs02:9466 EJB instance is called.
However when i start both servers in a clustered mode:
URL1=t3://pbwebs01:9466
and
URL2=t3://pbwebs02:9466
from t3://pbwebs01:9466 EJB instance -> call method resetCash() on t3://pbwebs02:9466 EJB instance
result:--> resetCash() on t3://pbwebs01:9466 EJB instance is called.
Here is the code:
for (all bean instances in a cluster)
Hashtable context_env = new Hashtable();
context_env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
context_env.put(Context.PROVIDER_URL, url);
context_env.put(Context.SECURITY_PRINCIPAL, uid);
context_env.put(Context.SECURITY_CREDENTIALS, password != null ? password : "");
InitialContext admctx = new InitialContext(context_env);
AdmUserHome admh = (AdmUserHome) admctx.lookup("AdmUserHome");
AdmUserRemote admr = admh.create();
admr.resetCash();
Any ideas?
Thanks in advance.

Answer 1

Since you are using clustered services WebLogic will always prefer local call vs remote.
You can use JMS (http://dima.dhs.org/misc/readOnlyUpdates.jar for example) to achieve this.
