Newbie question on howto run simple HelloWorld application

Hello,

I'm very new to j2ee and are trying to get my first app to run. I've written a stateless session bean and added it to an ear file and deployed this to application-deployments. when I try to run my HelloClient I gt the following error:

C:\WINDOWS\Profiles\Anders\Visual Studio Projects\Hello>java hello.HelloClient
javax.naming.NoInitialContextException: Need to specify class name in environmen
t or system property, or as an applet parameter, or in an application resource f
ile: 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 hello.HelloClient.main(HelloClient.java:14)

/Anders

// HelloClient.java:

package hello;

import javax.ejb.*;
import javax.naming.*;
import javax.rmi.*;
import java.util.Properties;

public class HelloClient{

public static void main(String args[]){
  try{
   Properties props = System.getProperties();
   Context context = new InitialContext(props);
   java.lang.Object objref = context.lookup("HelloHome");
   HelloHome home = (HelloHome)PortableRemoteObject.narrow(objref, HelloHome.class);

   Hello hello = home.create();

   System.out.println(hello.hello());
   hello.remove();
  }catch(Exception e){
   e.printStackTrace();
  }
}
}
