HI guys I have to develop an application where i have to build a bridge between two enterprise application and I am using JMS to establish the communication between these two application. Here I am using Message Driven Bean to send the JMS message from one application to another. I am struck where when my one application can send the message to other one but can not send the reply back to the requestor one.
private void sendJMSMessageToMyTestQueue(Message messageData) {
try {
context.createProducer().send(myTestQueue, messageData);
System.out.println("\tTime: " + System.currentTimeMillis() + " ms");
System.out.println("\tMessage ID: " + messageData.getJMSMessageID());
System.out.println("\tCorrel. ID: " + messageData.getJMSCorrelationID());
System.out.println("\tReply to: " + messageData.getJMSReplyTo());
//System.out.println("\tContents: " + messageData.getText());
} catch (JMSException ex) {
Logger.getLogger(HomeLoanJMS.class.getName()).log(Level.SEVERE, null, ex);
}
}
private void recieveSync() {
Message msg = context.createConsumer(myTestQueue).receive();
if (msg instanceof TextMessage) {
try {
TextMessage tms = (TextMessage) msg;
System.out.println("Received reply ");
System.out.println("Received reply ");
System.out.println("\tTime: " + System.currentTimeMillis() + " ms");
System.out.println("\tMessage ID: " + tms.getJMSMessageID());
System.out.println("\tCorrel. ID: " + tms.getJMSCorrelationID());
System.out.println("\tReply to: " + tms.getJMSReplyTo());
System.out.println("\tContents: " + tms.getText());
System.out.println("Coming Reply: ---->>>>" + tms.getText());
} catch (JMSException ex) {
Logger.getLogger(HomeLoanJMS.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
@Override
public void sendMessage(String message) {
try {
TextMessage msg = context.createTextMessage(message);
// msg.setJMSType("Textmsg");
msg.setText(message);
msg.setJMSReplyTo(myTestQueue); //setting reply destination
sendJMSMessageToMyTestQueue(msg);
System.out.println("after reply");
// recieveSync();
} catch (JMSException ex) {
Logger.getLogger(HomeLoanJMS.class.getName()).log(Level.SEVERE, null, ex);
}
}
But when this message is received by the replier I does print the getReplyTo destination but when i build a reply and send it back it set the destination value as null and reply is never executed. the replier code is given below
@MessageDriven(activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
, @ActivationConfigProperty(propertyName = "destinationLookup", propertyValue = "jms/myTestQueue")
})
public class TestingMDB implements MessageListener {
@EJB
private SavingBeanRemote savingBean;
@Resource(mappedName = "jms/myTestQueue")
private Queue myTestQueue;
@Inject
@JMSConnectionFactory("jms/myTestQueueConnectionFactory")
private JMSContext context;
public TestingMDB() {
}
@Override
public void onMessage(Message message) {
try {
if (message instanceof MapMessage) {
MapMessage mmsg = (MapMessage) message;
String id = mmsg.getString("messageType");
System.out.println(id);
String cid = mmsg.getString("C_ID");
System.out.println(cid);
} else if (message instanceof TextMessage && (message.getJMSReplyTo() != null)) {
TextMessage tm = (TextMessage) message;
System.out.println("Received request");
System.out.println("\tTime: " + System.currentTimeMillis() + " ms");
System.out.println("\tMessage ID: " + tm.getJMSMessageID());
System.out.println("\tCorrel. ID: " + tm.getJMSCorrelationID());
System.out.println("\tReply to: " + tm.getJMSReplyTo());
System.out.println("\tContents: " + tm.getText());
String contents = tm.getText();
Double balance = savingBean.getBalance("c0566664", "a4016692");
String text = (String)balance.toString();
Destination replyDestination = (Destination)message.getJMSReplyTo();
TextMessage replyMessage = context.createTextMessage();
replyMessage.setText(text);
replyMessage.setJMSCorrelationID(tm.getJMSMessageID());
context.createProducer().send(replyDestination, replyMessage);
System.out.println("Sent reply");
System.out.println("\tTime: " + System.currentTimeMillis() + " ms");
System.out.println("\tMessage ID: " + replyMessage.getJMSMessageID());
System.out.println("\tCorrel. ID: " + replyMessage.getJMSCorrelationID());
System.out.println("\tReply to: " + replyMessage.getJMSReplyTo());
System.out.println("\tContents: " + replyMessage.getText());
TextMessage tms = context.createTextMessage("Reply from Client");
for (int i = 0; i < 2; i++) {
try {
try {
System.out.println(message.equals(tm));
Thread.sleep(1000);
System.out.println(tm.getText());
System.out.println(tm.getText());
} catch (InterruptedException ex) {
Logger.getLogger(TestingMDB.class.getName()).log(Level.SEVERE, null, ex);
}
} catch (JMSException ex) {
Logger.getLogger(TestingMDB.class.getName()).log(Level.SEVERE, null, ex);
}
}
} else {
System.out.println("error");
}
} catch (JMSException ex) {
Logger.getLogger(TestingMDB.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
so what is happening that i can send a message but can not receive the reply. please help me what am i missing or doing wrong. thanks
