Hello again,
I don't know why, but I'm still (again?) facing problems concerning cluster node auto detection.
I have now the following properties for the InitialContext:
Properties prop = System.getProperties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
prop.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
prop.put(Context.PROVIDER_URL, "");
I think these are right because sometimes I get a connection and am able to lookup my stateless session bean.
But most of the times it doesn't work. I think it works more often when I started the cluster nodes freshly, but I don't know if that is just my imagination.
It would be really great if somebody could help me with this problem. Perhaps someone out of the JGroups team.
By the way, here is the stacktrace of the exception when my client doesn't get a connection.
javax.naming.CommunicationException: Receive timed out. Root exception is java.net.SocketTimeoutException: Receive timed out

HA-JNDI discovery is *not* done by JGroups. Can you increase the timeout value for jnp.discoveryTimeout, to e.g. 10000 ? Also, try putting a list of at least some of your servers in PROVIDER_URL. If none are found, only then do we use multicast discovery.
