j2ee newbie question about context and lookup

[raminaa niilian]

Ok
My problem goes deepr than what i suggest at first.
I post another mesage in sun apps section but now my problem goes general :
I have some question about context , jndi ...

1- what does "java:comp/env/" means ?
should i put the last forward slash ?
2- how i should use context and initial context etc.. ?
here is my situation :
I defined two jms resource from the admin console of Sun Apps 8.1: one factory with exact jndi name of : jms/QueueFactory
and one queue with exact name of : jms/dest/queueDestination
Now i tried to access them but i simply can not
it trows exception : javax.naming.NameNotFoundException: No object bound for java:comp/env/jms/QueueFactory
i tried and removed java:comp/env/ from my lookup string with no luck
can some one help me and tell me that :
1-when does that java:comp/env/ is required ?
2-is my following code true ? i write them in netbeans.

 Properties env = new Properties();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.SerialInitContextFactory");
        env.put(Context.PROVIDER_URL, "localhost:3700");
 
     try{
        Context ctx = new InitialContext(env);
        //ctx.lookup("java:comp/env");
     QueueConnectionFactory qcf = (QueueConnectionFactory)ctx.lookup("java:comp/env/jms/QueueFactory ");
     Destination qd = (Destination)ctx.lookup("jms/dest/queueDestination");
     Connection con = qcf.createConnection();
     Session session = con.createSession(false,Session.AUTO_ACKNOWLEDGE);
     
     
     MessageProducer prod =session.createProducer(qd);
    TextMessage msg = session.createTextMessage("Im the message");     
     prod.send(msg);
     System.out.println("I send the message");
 
     
     MessageConsumer cons = session.createConsumer(qd);
     TextMessage txtmsg = (TextMessage)cons.receive();
     System.out.println(txtmsg+ "  is recived message");
     }
     catch(Exception e){
         e.printStackTrace();
         System.out.println("I get the exception");
         
     }
     

I think that my poblem is about the class name for initial_Context_name and provider_url
also with the lookup String.
sorry if it goes too long

Aha i made some changes and it works but now it gives another very long exception
the change which i made is i made a typo in QueuesFactory and put an space in its end

QueueConnectionFactory qcf = (QueueConnectionFactory)ctx.lookup("jms/QueuesFactory");

and the long long exception is :
