I wrote an application client to execute function on EJB, Client Code is this:
"try {
Context ic = new InitialContext(); // entry point in JNDI service
System.out.println("first line executed");
Object o = ic.lookup("AdviceHome"); // lookup for Advice Bean
System.out.println("second line executed");
AdviceHome home = (AdviceHome) PortableRemoteObject.narrow(o,
AdviceHome.class);
System.out.println("third line executed");
Advice advisor = home.create();
System.out.println("fourth line executed");
System.out.println( advisor.getAdvice() );

}"

It compiles well but when I tried to execute, it issues following error on 3rd
line :
