| props.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");

|
| Context ctx = new InitialContext(props);
|
| System.out.println("It;s ok");
|
|
| HelloLocalHome home=(HelloLocalHome) ctx.lookup("java/env/ejb/alr");
| HelloLocal bean = home.create();
| String hello= bean.hello();
| bean.remove();
| ctx.close();
What is the wrong in above code. Please tell me. I have been trying for this.
some issues:
1. If i don't write optional jboss.xml what is the optional jndi name for jboss4.0.2
2. while calling local ejb on same machine, jndi properties are not required. can you
confirm?
Advanced thanks. Please give answer
