[jboss-user] [JNDI/Naming/Network] - Communication Exception in JBoss Cluster while connecting t
Hi Everyone,
I am using JBoss in clustered mode !!!
My JBoss running Environment was:
1. JBoss running with options : -b myhostName -g mypartitionName -c ALL
2. JBoss is running on Windows XP
3. System is using Two LAN's(one of them is rendering Video's) where the JBoss
server is running.
4. Client is also running in the same machine.
5. JBoss Version is 4.2.3GA
6. using EJB 3.0
Problem:
If I use Two LAN's(as I mentioned above) I am unable to connect, and my application is
throws below Communication Exception
If I disable the video LAN and restart JBoss server, my application connects with out any
Exception.
I am getting following Exception :

My Connction Parameters are :
Properties props = new Properties();
props.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
props.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
props.put("jnp.partitionName", "MY_PARTITION");
InitialContext ctx;
try
{
ctx = new InitialContext(props);
MyService connection = (MyService) ctx.lookup("MyServiceImpl/remote");
System.out.println("Connection : " + connection);
}
catch (NamingException anException)
{
// TODO Auto-generated catch block
anException.printStackTrace();
}
I am unable to sort it out :(
Can any body provide/suggest me the solution?
What's the problem in identifying the partition? and
How it is related to Network/Number of LAN's on a Computer?
Thanks in Advance,
Jagan.
