Steps to send and receive messages using JMS

However, before we start using JMS APIs, let's take a look at the generic steps involved in using them. The following steps show how to send a message to a queue and receive it. Although the steps focus on queues, the steps for topics are similar, but with appropriate topic-related classes:

1. Look up ConnectionFactory using JNDI:

InitialContext ctx = new InitialContext(); 
QueueConnectionFactory connectionFactory = (QueueConnectionFactory)initCtx.lookup("jndi_name_of_connection_factory"); 

2. Create a JMS connection and start it:

QueueConnection con = connectionFactory.createQueueConnection(); 
con.start(); 

3. Create a JMS session:

QueueSession session = con.createQueueSession(false, Session.AUTO_ACKNOWLEDGE); 

4. Look up JMS Queue/Topic:

Queue queue = (Queue)initCtx.lookup("jndi_queue_name");
