Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file - jboss

Question

I'm new to JMS and I'm studying the following example
public class SendRecvClient
{
static CountDown done = new CountDown(1);
QueueConnection conn;
QueueSession session;
Queue que;
public static class ExListener
implements MessageListener
{
public void onMessage(Message msg)
{
done.release();
TextMessage tm = (TextMessage) msg;
try {
System.out.println("onMessage, recv text=" + tm.getText());
} catch(Throwable t) {
t.printStackTrace();
}
}
}
public void setupPTP()
throws JMSException,
NamingException
{
InitialContext iniCtx = new InitialContext();
Object tmp = iniCtx.lookup("ConnectionFactory");
QueueConnectionFactory qcf = (QueueConnectionFactory) tmp;
conn = qcf.createQueueConnection();
que = (Queue) iniCtx.lookup("queue/testQueue");
session = conn.createQueueSession(false,
QueueSession.AUTO_ACKNOWLEDGE);
conn.start();
}
public void sendRecvAsync(String text)
throws JMSException,
NamingException
{
System.out.println("Begin sendRecvAsync");
// Setup the PTP connection, session
setupPTP();
// Set the async listener
QueueReceiver recv = session.createReceiver(que);
recv.setMessageListener(new ExListener());
// Send a text msg
QueueSender send = session.createSender(que);
TextMessage tm = session.createTextMessage(text);
send.send(tm);
System.out.println("sendRecvAsync, sent text=" + tm.getText());
send.close();
System.out.println("End sendRecvAsync");
}
public void stop()
throws JMSException
{
conn.stop();
session.close();
conn.close();
}
public static void main(String args[])
throws Exception
{
SendRecvClient client = new SendRecvClient();
client.sendRecvAsync("A text msg");
client.done.acquire();
client.stop();
System.exit(0);
}
}
I ran this in JBoss and it gave the following exception
Begin sendRecvAsync

I think this is an error with JNDI name, but I couldn't find which xml file to edit in JBOSS to over come this problem. Please some one help me.
