      Hi,
      thank you, I'm now able to deploy my bean.
      But now, I don't get the client started.
      In my bean, I have the "jboss.xml" with the following code:

      <jboss>
 <enterprise-beans>
 <session>
 <ejb-name>KontoBean</ejb-name>
 <jndi-name>ejb/KontoBean</jndi-name>
 </session>
 </enterprise-beans>
<resource-managers>
 </resource-managers>
</jboss>


      Here is my client code: 
      import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.util.*;


public class HelloWorldClient
{
 public static void main(String[] args)
 {
 try
 {
 // Die EJB Über JNDI ermitteln
 Context initial = new InitialContext();
 System.out.println(initial);
 Object ref = initial.lookup("java:comp/env/ejb/KontoBean");
 // Home-Interface referenzieren
 KontoHome home = (KontoHome)
 PortableRemoteObject.narrow
 (ref, KontoHome.class);
 // Konto-Bean referenzieren
 Konto konto = home.create();
 // Konto-Methoden nutzen
 System.out.println ("Startguthaben: "
 + konto.getKontostand());
 konto.einzahlen (1000);
 System.out.println ("Neues Guthaben: "
 + konto.getKontostand());
 double betrag = konto.abheben (500);
 System.out.println ("Abgehoben: " + betrag
 + "; neues Guthaben: "
 + konto.getKontostand());
 }
 catch(Exception e)
 {
 System.out.println ("Ein Fehler ist aufgetreten!");
 e.printStackTrace();
 }
 }
}


      From this, I get the exception:

      javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
      at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
      at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
      at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
      at javax.naming.InitialContext.lookup(Unknown Source)
      at HelloWorldClient.main(HelloWorldClient.java:24)


      If I use the following client code: 
      import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.util.*;


public class HelloWorldClient
{
 public static void main(String[] args)
 {
 try
 {
 // Die EJB Über JNDI ermitteln
 Properties p = new Properties();
 p.put(Context.INITIAL_CONTEXT_FACTORY,
 "org.jnp.interfaces.NamingContextFactory");
 p.put(Context. PROVIDER_URL, "jnp://localhost:1099");
 Context initial = new InitialContext(p);
 System.out.println(initial);
 Object ref = initial.lookup("java:comp/env/ejb/KontoBean");
 // Home-Interface referenzieren
 KontoHome home = (KontoHome)
 PortableRemoteObject.narrow
 (ref, KontoHome.class);
 // Konto-Bean referenzieren
 Konto konto = home.create();
 // Konto-Methoden nutzen
 System.out.println ("Startguthaben: "
 + konto.getKontostand());
 konto.einzahlen (1000);
 System.out.println ("Neues Guthaben: "
 + konto.getKontostand());
 double betrag = konto.abheben (500);
 System.out.println ("Abgehoben: " + betrag
 + "; neues Guthaben: "
 + konto.getKontostand());
 }
 catch(Exception e)
 {
 // System.out.println("Ein Fehler ist aufgetreten!");
 e.printStackTrace();
 }
 }
}


      Then I get:
      javax.naming.NameNotFoundException: comp not bound

      Please help me that my client is able to communicate the my bean.

      Regards,
      PeaceMaker
