My code is below:

try {
java.util.Hashtable JNDIParm = new java.util.Hashtable();
JNDIParm.put(Context.PROVIDER_URL, "localhost");
JNDIParm.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
jndiContext = new InitialContext(JNDIParm);
} catch (NamingException e) {
System.out.println("Could not create JNDI API " +
"context: " + e.toString());
System.exit(1);
}
try {
queueConnectionFactory = (QueueConnectionFactory)
jndiContext.lookup("JBossMQProvider");
queue = (Queue) jndiContext.lookup(queueName);
} catch (NamingException e) {
System.out.println("JNDI API lookup failed: " +
e.toString());
System.exit(1);
}

JBossMQProvider
when my program run, it throws an exception,
JNDI API lookup failed: javax.naming.NameNotFoundException: JBossMQProvider not bound

who can Help?
thank you

the result of look UIL2ConnectionFactory is

JNDI API lookup failed: javax.naming.NameNotFoundException: UIL2ConnectionFactory not bound.
Maybe I think the JNDI name is in a file?
but I can't fiind it.

to Adrian:
I run my program while JBoss is running.
but it still does not work.
Follow is JNDIContext:
java.util.Hashtable JNDIParm = new java.util.Hashtable();
JNDIParm.put(Context.PROVIDER_URL, "localhost");
JNDIParm.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
jndiContext = new InitialContext(JNDIParm);
when I use it to look up EntityBean,it runs well.

package simple;
import javax.jms.*;
import javax.naming.*;

public class SimpleQueueReceiver {
public static void main(String[] args) {
String queueName = "A";
Context jndiContext = null;
QueueConnectionFactory queueConnectionFactory = null;
QueueConnection queueConnection = null;
QueueSession queueSession = null;
Queue queue = null;
QueueReceiver queueReceiver = null;
TextMessage message = null;
System.out.println("Queue name is " + queueName);
try {
// jndiContext = new InitialContext();
java.util.Hashtable JNDIParm = new java.util.Hashtable();
JNDIParm.put(Context.PROVIDER_URL, "localhost");
JNDIParm.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
jndiContext = new InitialContext(JNDIParm);

queueConnectionFactory = (QueueConnectionFactory)
jndiContext.lookup("ConnectionFactory ");
queue = (Queue) jndiContext.lookup(queueName);

queueConnection =
queueConnectionFactory.createQueueConnection();
queueSession =
queueConnection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);
queueReceiver = queueSession.createReceiver(queue);
queueConnection.start();
while (true) {
Message m = queueReceiver.receive(1);
if (m != null) {
if (m instanceof TextMessage) {
message = (TextMessage) m;
System.out.println("Reading message: " +
message.getText());
} else {
break;
}
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (queueConnection != null) {
try {
queueConnection.close();
} catch (JMSException e) {}
}
}
}
}

Up is my JMS reciever. I known there is a default Queue named "A".But How can I get ConnectionFactory?Is there a JNDI name I can use and what is it?

Queue name is A

This is the error message when it runs.

Thank you,everyone.
The problem has resovled.
