java.rmi.NotBoundException

Question

i have written small RMI chat program and its compiling properly.but when i try to run Client program it results exception "java.rmi.NotBoundException - ServerInterface" Server program runs without any errors..please help me to solve this.

here is some of Client code

public static void main (String[] args)
{
String address = "rmi://localhost/ServerInterface";
try
{
ServerInterface si= (ServerInterface) Naming.lookup(address);
new Thread(new Client(si)).start();
}
catch (Exception e)
{
System.err.println(e.toString()) ;
}
}

Solution 1

A NotBoundException is thrown if an attempt is made to lookup or unbind in the registry a name that has no associated binding.

What is your server code look like? This exception you are having most likely caused by server not set up properly.

I think in your server code you are bind with name ChatServer

 Naming.rebind("ChatServer", new Server());

But in your client code you are using ServerInterface name

String address = "rmi://localhost/ServerInterface";

For more details Naming

Solution 2

It looks like you are attempting to look up a name that is not bound.

public class NotBoundException extends Exception

A NotBoundException is thrown if an attempt is made to lookup or unbind in the registry a name that has no associated binding.

@SumitSingh I read your answer. I am asking you a question about it. You haven't answered it. 'Mainly' implies that there are other causes. What other cause is there?

@SumitSingh Wrong again, nothing to do with me, and no misunderstanding either. Just a complete failure to answer my question.

@MukulGoel I could show you dozens. I saw one today with a tick and 20 upvotes that went to 19 for some unexplained reason.
