JNDI problem

[lukio]

How use lookup method to find simple bean that return String "hello world".

The folder structure within the Ejb-jar file looks as follows:
META-INF/
META-INF/MANIFEST.MF
examples/
examples/HelloBean.class
examples/HelloHome.class
examples/Hello.class
examples/HelloLocal.class
examples/HelloLocalHome.class
META-INF/ejb-jar.xml

J have write a class HelloClient

public class HelloClient {
 public static void main(String[] args) throws Exception {
 Properties props = System.getProperties();
 Context ctx = new InitialContext(props);
 Object obj = ctx.lookup("HelloHome");
 HelloHome home = (HelloHome)
 javax.rmi.PortableRemoteObject.narrow(
 obj, HelloHome.class);
 Hello hello = home.create();
 System.out.println(hello.hello());
 hello.remove();
 }
}

but this

Object obj = ctx.lookup("HelloHome");

Exception in thread "main" 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

Instead of passing the system properties into the constructor just put a file called jndi.propertied on the classpath of the client app with the following properties: -

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://127.0.0.1:1099
java.naming.factory.url.pkgs=org.jboss.naming
