what are the INTIAL_CONTEXT parameters

[Raja Sagar Panamgipalli]

Hello there...

Guys,i'm not able understand what to insert here in the HelloClient program ..ie..while getting the initialcontext...
i haven't really gone through the documentation ..plz help me as to why this is needed...

 private Context getInitialContext() throws NamingException {
    Hashtable environment = new Hashtable();
    environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
    environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming :-o	 rg.jnp.interfaces");
    environment.put(Context.PROVIDER_URL, "jnp://localhost:8080");
    return new InitialContext(environment);
  }
 

Is the above correct...its autogenerated by the IDE...
when i compile the Hworld Client i also get the exception as below...

  javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out]

hi,

simple solution
change environment.put(Context.PROVIDER_URL, "jnp://localhost:8080");
to environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");
and make sure your JBoss is running :-)
