Hi all,
I have 2 JBoss instances (3.2.3 on Windows 2003) in a cluster, and I have a client
Java application (in a separate VM) that tries a JNDI lookup. The Jndi.Properties of
the client is:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
So since provider url is not defined, it should look for the HA Jndi.
I create the initial context in the usual way:
javax.naming.InitialContext initialContext = new javax.naming.InitialContext();
when I do initialContext.lookup(), it succeeds or fails as follows:
If the 2 JBoss instances are up, the lookup succeeds.
If the 2 JBoss instances were up, and then one goes down, I am left with a single
JBoss - the lookup succeeds.
If only a single JBoss is up, the lookup fails!
The exception I get is below.
Is this behavior by design or is it a bug.
If it is by design, what is the intention of this design. I would like the client to
succeed in all cases. Why should it care that the cluster has only 1 node?
TIA
Evyatar.
