 Example 1 - publish specifying delay, correlation

TopicConnectionFactory    tc_fact   = null;
TopicConnection           t_conn    = null;
TopicSession              jms_sess;
TopicPublisher            publisher1;
Topic                     shipped_orders;
int                       myport = 5521;

/* create connection and session */
tc_fact = AQjmsFactory.getTopicConnectionFactory("MYHOSTNAME",
                                                  "MYSID", myport, "oci8");
t_conn = tc_fact.createTopicConnection("jmstopic", "jmstopic");
jms_sess = t_conn.createTopicSession(true, Session.CLIENT_ACKNOWLEDGE);    
  
shipped_orders = ((AQjmsSession )jms_sess).getTopic("OE", "Shipped_Orders_
Topic");
publisher1 = jms_sess.createPublisher(shipped_orders);

/* create text message */
TextMessage     jms_sess.createTextMessage();

/* Set correlation and delay */

/* set correlation */
jms_sess.setJMSCorrelationID("FOO");

/* set delay of 30 seconds */
jms_sess.setLongProperty("JMS_OracleDelay", 30);

/* publish  */
