JNDI lookup failing in clustered environment in JBoss-3.2.3

[ashankerdas]

Hi,
I have trying, without success, since the past few days, to lookup a bean in a clustered environment. I am using JBoss-3.2.3
Here is my scenario:
There are 2 nodes in my cluster. Say node1 and node2
I have a bean "MySampleBean" deployed on both the nodes and set the atttribute to "true".
The bean is bound to jndi name "MySampleBean".

I startup both the nodes. I have a standalone code on node1 which looks up "MySampleBean". I carry out the lookup as follows:

Context ctx = new InitialContext();
ctx.looup("MySampleBean");

My jndi.properties file contains the following:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

I keep getting the following error:

javax.naming.CommunicationException: Failed to retrieve stub from server 0.0.0.0:1100

Sometimes i even get "ReceiveTimedOut" error.

Can anyone suggest a solution for this?
