Instead of Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); p.put(Context.URL_PKG_PREFIXES, "jboss.naming:org.jnp.interfaces"); p.put(Context.PROVIDER_URL, "localhost:1100"); // HA-JNDI // port initial = new InitialContext(p); i did this : Hashtable env = new Hashtable(); env.put("jnp.partitionName", "IndicsPartition"); env.put("jnp.discoveryGroup", "230.0.0.5" ); initial = new InitialContext(p); and i changed the ip in the indicspartition machine to 230.0.0.5 i got a communication exception on the client side ?? is this all or am i missing something ?
