try{
System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url", "localhost:1099");
Context context = new InitialContext();
try{
home = (StudentHome)PortableRemoteObject.narrow(context.lookup("Student"), StudentHome.class);
}catch(Exception e){System.out.println("err in StudentHome"+e);}
/* try{
home.create("Ammamn","A01");
}catch(Exception e){System.out.println("err in HomeCreate"+e);}*/
}catch(Exception e){System.out.println("error in client"+e);}
System.out.println("i am in end");

Try this,
Context context = new InitialContext(System.getProperties());
