The following code establishes the initial JNDI context, which represents the JNDI configuration:

Hashtable<String, String> jndiEnvironment = new Hashtable<String, String>();

// set the factory class
jndiEnvironment.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.qpid.jndi.PropertiesFileInitialContextFactory");

// set the connection factory name 
jndiEnvironment.put("connectionfactory.ConnectionFactory",
     "amqp://username:password@clientid/test?brokerlist='tcp://localhost:5672'");

// Set the provider URL that points to a property file     
jndiEnvironment.put(Context.PROVIDER_URL, "myPRoviderURLPath");

// create the initial context 
InitialContext initialContext = new InitialContext(jndiEnvironment);

Once the JNDI configuration has been created, we can get the connection factory as follows:

ConnectionFactory connectionFactory = (ConnectionFactory) initialContext.lookup("ConnectionFactory");

The connection factory is used to create a connection, and the connection is used to create a session, as follows:

Connection connection = connectionFactory.createConnection("guest", "guest");
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

Programs that use JNDI close both the connection and the JNDI context, as follows:

connection.close();
getInitialContext().close();
