Hello,
I am using JBoss 4.0.2, JDK 1.5.0_03 & Eclipse 3.02 and I have successfully
deployed the "Fibonaci Computation"-application from the JBoss-Eclipse-Tutorial.
Now I want to connect to the Fibo-EJB from a swing-client with the following
program:
import java.util.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import tutorial.interfaces.FiboHome;
public class SwingClient {
public static void main(String[] args) {
try {
Hashtable props = new Hashtable();
props.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
props.put("java.naming.provider.url",
"jnp://localhost:1099");
props.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
Context context = new InitialContext(props);
Object ref = context.lookup("java:/comp/env/ejb/Fibo");
} catch (Exception ex) {
System.err.println("Caught an exception:");
ex.printStackTrace();
}
}
}
After running this program, an exception is occurred:
Caught an exception:
javax.naming.NameNotFoundException: comp not bound

at client.SwingClient.main(SwingClient.java:39)
This line doesn't work:
Object ref = context.lookup("java:/comp/env/ejb/Fibo");
But what's wrong with my code?
