I am following the book, EJB3 in Action
As i was running, chapter- 4 examples under eclipse:

i used to get some error like createActiveAdapter rar

in order to resolve this issue, i did two steps-

1) in glassfish server, i added additional property under

jms resources>> connection factories

Name- jms/QueueConnectionFactory

2) in my client code, i did initalcontext lookup for this jms/QueueConnectionFactory.

now i am able to run my code very well.

So my code now looks like-

----------------------------------------------------------------------
InitialContext ctx = new InitialContext();
Destination destination = (Destination)ctx.lookup("ShippingRequestQueue");
InitialContext ctx1 = new InitialContext();
ConnectionFactory connectionFactory = (ConnectionFactory)ctx.lookup("jms/QueueConnectionFactory");
Connection connection = connectionFactory.createConnection();
connection.start();

------------------------------------------------------------------------

So now i am doing jndi lookup for 2 jndi name's.

Question-1- if i remember correctly, somewhere in book, i read, that we can't do lookup for jndi name in 1 program 2 time's.

Question-1.1- As i have seen on other forum's, people doing jndi lookup for jms/QueueConnectionFactory,
they are actually adding these line's to code to do,

----------------------------------------------
Hashtable properties = new Hashtable(2);
properties.put(Context.PROVIDER_URL,"iiop://127.0.0.1:3700");
properties.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.appserv.naming.S1ASCtxFactory");
try {
ctx = new InitialContext(properties);
} catch (NamingException ex) {
ex.printStackTrace();
}
------------------------------------------

But in my case, i didn't did this, instead- i added property under glassfish under jms/QueueConnectionFactory,

so is this my step manual replacement for adding above line's of code?

Question-2- in this program- /Chapter - 4 EJB Project/src/actionbazaar/buslogic/ShippingRequestProcessorMDB.java

@Resource(name = "jdbc/TurtleDS")

we are injecting the resource. but my question here is how this jdbc resource was created under glassfish server. I am unable to point out, how this magic is happening.

Question-3- i have run this program /Chapter - 4 Client Project/src/actionbazaar/buslogic/ShippingRequestJMSProducer.java 1 time only, but it seems that at eclipse console output,
Shipping Request Message Sent ..

i see in console output, this below message keep on updating after session time, what sort of this message represents info to us?
