EJB client cannot connect: [SocketServerInvoker] Failed to a
Hi guys!
I have developed a very simple EJB with the JBoss IDE 1.5:
Here is the EJB:
Interface:
package src;
import javax.ejb.Remote;
@Remote
public interface MyCalculator
{
int add(int x, int y);
int sub(int x, int y);
}
Implementation:
package src;
import javax.ejb.Stateless;
import src.MyCalculator;
public @Stateless class MyCalculatorBean implements MyCalculator {
public int add(int x, int y)
{
return x+y;
}
public int sub(int x, int y)
{
return x-y;
}
}
jndi.properties:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces java.naming.provider.url=localhost:1099
It deployed successfully.
Next I developed the client.
First I got some ClassNotFoundException for the class EJBMetaDataImpl. Luckily that problem could be solved as I found another thread stating that the client project needs the jboss-client.jar.
Here ist the client:
import java.rmi.RMISecurityManager;
import java.util.Enumeration;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import src.MyCalculator;
public class MyCalculator_Client
{
/**
* @param args
*/
public static void main(String[] args)
{
try
{
System.setSecurityManager(new RMISecurityManager());
InitialContext ctx = new InitialContext();
MyCalculator myCalculator = (MyCalculator) ctx
.lookup("MyCalculatorBean/remote");
System.out.println("1+2=" + myCalculator.add(1, 2));
} catch (Exception e)
{
e.printStackTrace(System.err);
}
}
}
Here is the exception during invocation:

Any idea?
Thanks!
