Like:
        Properties p = new Properties();
        p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.RemoteInitialContextFactory");
        p.setProperty(Context.PROVIDER_URL, "ejbd://localhost:4201");
        Context initialContext=null;
        try {
            initialContext=new InitialContext(p);
                       
            Object object1 = initialContext.lookup("Secure3Remote");
            Secure3Remote s3r=(Secure3Remote)object1;
           
        } catch (NamingException e) {
            e.printStackTrace();
        }
