[Design of Messaging on JBoss (Messaging/JBoss)] - Problem in running the JMS program in JbossMq
by milinduc
I am completely new to jbossmq I got the probel in running jmms programs. Herer I created the two jms files one is message to que and que to message.
message to que:->
package src.jms;
import javax.jms.*;
import javax.naming.*;
import java.util.Hashtable;
import java.util.Properties;
public class MessageToQueue
{
public static void main(String[] args)
{
QueueConnectionFactory cf;
QueueConnection connection;
QueueSession session;
Queue destination;
QueueSender sender;
TextMessage message;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1199");
try {
Context ctx = new InitialContext(env);
/* ctx = new InitialContext(); */
cf = (QueueConnectionFactory) ctx.lookup("/ConnectionFactory"); destination = (Queue)ctx.lookup("queue/testQueue");
connection = cf.createQueueConnection();
session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
sender = session.createSender(destination);
message = session.createTextMessage();
message.setText("Hello World!");
System.out.println("Sending Message.");
sender.send(message);
connection.close();
System.out.println("Done.");
}
catch (NamingException e) {
e.printStackTrace();
}
catch (JMSException e) {
e.printStackTrace();
}
}
}
que to message:->
package src.jms;
import javax.jms.*;
import java.util.Hashtable;
import java.util.Properties;
import javax.naming.*;
/**
* Receives a TextMessage from a Queue
*/
public class QueueToMessage
{
public static void main(String[] args)
{
QueueConnectionFactory cf;
QueueConnection connection;
QueueSession session;
Queue destination;
QueueReceiver receiver;
TextMessage message;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "172.24.1.226:1199");
try {
Context ctx = new InitialContext(env);
cf = (QueueConnectionFactory) ctx.lookup("/ConnectionFactory");
destination = (Queue) ctx.lookup("queue/testQueue");
connection = cf.createQueueConnection();
session = connection
.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
receiver = session.createReceiver(destination);
System.out.println("Waiting For A Message.");
connection.start();
message = (TextMessage) receiver.receive();
System.out.println("The message was: " + message.getText());
connection.close();
System.out.println("Done.");
}
catch(JMSException e){
e.printStackTrace();
}
catch(NamingException e){
e.printStackTrace();
}
}
}
