Sending and Receiving Messages Using Queues

The following should be noted if you are writing a similar sample:

• It is not possible to use the @ symbol in the username or password.

  It is also not possible to use the percentage (%) sign in the password. When building the connection string URL inside the andes client code of MB, the URL is parsed. This parsing exception happens because the percentage (%) sign acts as the escape character in URL parsing. If using the percentage (%) sign in the connection string is required, use the respective encoding character for the percentage (%) sign in the connection string. For example:

  If you need to pass adm%in as the password, then the % should be encoded with its respective URL encoding character. Therefore, you have to send it as adm%25in.

  For a list of possible URL parsing patterns, see URL encoding reference.
   

• In addition to using javax.jms.QueueSender class to send the messages you can also use a javax.jms.MessageProducer client and send the messages to a destination queue. Following is the way of creating a JMS MessageProducer.

  javax.jms.MessageProducer messageProducer = queueSession.createProducer(queue);

  messageProducer.send(textMessage);

  messageProducer.close();
   

• When subscribing and publishing to a queue in a tenant the qualified queue name, DOMAIN_NAME/Queuename should be given as follows.

  String queueName = "mydomain.com/testQueue";

  Queue queue = (Queue) ctx.lookup(queueName);
