Hello,
we´re porting an application which worked on one single JBoss without any
problems. Actually we configured a Cluster with 2 nodes via a
multicast-address. When we do a ping to the multicast-ip theese both nodes
answers fine (and only theese two nodes)
Our JNDI-Lookup looks like this:
| Hashtable props = new Hashtable();
| props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
| props.put(Context.PROVIDER_URL,
"jnp://localhost:1100,jnp://172.17.28.13:1100");
|
The Client (a Swing Apllication called via Webstart) fails then with the
following Exception:

| javax.naming.CommunicationException: Failed to retrieve stub from server
localhost:1100 [Root exception is java.io.StreamCorruptedException: unexpected

When i try a call via telnet ( telnet localhost 1100) then i can see that the
server respondes with a serializied Object ( probably the needed stub from
JBoss) This looks like this:

The only thing we changed actually is that we entered a clustered=true into our
beans and that we changed our server conf to the default "all" configuration
where we added our multicast-address
We don´t need any cluster-services for Tomcat so we left all the needed files
in original
Any help is appreciated
Regards
Achim
