Hi,
I have a peculiar problem which I am unable to decipher. Please allow me to
explain it.
I have an instance of JBoss server running on a box A(IP: 10.8.24.250). On
another box B(IP: 10.8.24.236), I am trying to lookup an EJB deployed on the
JBoss server on A. The code looks like the following:
|
| import java.util.Hashtable;
|
| import java.net.Socket;
| import javax.ejb.EJBHome;
| import javax.naming.Context;
| import javax.naming.InitialContext;
| import javax.naming.NamingEnumeration;
| import javax.naming.NamingException;
| import javax.rmi.PortableRemoteObject;
|
| public class SchedulerClient
| {
| public static void main(String[] args) throws Exception
| {
| Hashtable props = new Hashtable();
| props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| props.put(Context.PROVIDER_URL, "10.8.24.250:1099");
| InitialContext ctx = new InitialContext(props);
| //Socket sock = new Socket("10.8.24.250", 1099);
| //System.out.println("The socket has been created successfully: "+
sock);
| Object obj = ctx.lookup("com.abc.scheduler.ejb.SchedulerManager");
| SchedulerManagerHome home = (SchedulerManagerHome)
PortableRemoteObject.narrow(obj, SchedulerManagerHome.class);
| System.out.println("Got the home object :" + home);
| System.out.println("Got the ejb object :" + home.create());
| }
| }
|
If I run this client application on box A, it works absolutely fine and returns
me the correct EJB instance.
However, if I run the same code from machine B, it throws me the following
error:
2006-09-14 05:10:27,442 ERROR [com.nubridges.framework.ejb.EJBHomeFactory]

at SchedulerClient.lookup(...)
I fail to understand the reason. Both the boxes are Linux boxes running with
Java 5. The JBoss version in 4.0.2.
One more thing, if both the boxes are windows boxes, the same code works fine
on both of them. Any clues what am I doing wrong?
Thanks,
Deepak.
