Sorry to ask so many questions in one here. I'm not sure if this is the same
problem or not. I've got jBoss running and the bean deployed. I have a program
that does this:
System.out.println("Starting");
Context jndiContext = null;
Hashtable env = new Hashtable();
String searchfor="ADMIN";
try {
searchfor=args[0];
} catch (Exception e) {}
System.out.println("1 Setting env");
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "206.233.214.192:1099");
System.out.println("2 Loading InitialContext");
jndiContext = new InitialContext(env);
System.out.println("Got initial context\n");
System.out.println("3 Account EJB Test\n");
AccountHome accountHome =
(AccountHome)PortableRemoteObject.narrow(jndiContext.lookup("accountEJB"),
AccountHome.class);
System.out.println("4 Made AccountHome\n");
Account a1 = accountHome.findByPrimaryKey(searchfor);
When I run it (local to JBoss) from Linux it does this:
Starting
1 Setting env
2 Loading InitialContext
Got initial context
3 Account EJB Test

There was a question similar to this a while back. But what code am I supposed to
use? Am I supposed to cast jndiContext.lookup()?
==========================================================
When I run the same program (remote) from Windows, it does this:
Starting
1 Setting env
2 Loading InitialContext
Got initial context

This is the connection refused error. But it seems to get this error every time
(if jBoss is running remote on Linux) yet it has never done it if jBoss is running
on the same Windows machine.
What am I doing wrong? And why does it say "connection refused to localhost?"
since I'm not trying to connect to localhost.
Regards and many thanks,
