generating Destinatios programatically

Yes you can but the methods are not part of the JMS spec - they are vendor specific. The code below is an example of how to create a topic for Oracle AQ. As to whether it is temperory or permanant is dependant on your code.

You can, of course, create durable subscritpions to topics at runtime through JMS.

public void createTopic(String topicName) throws AQException{

AQQueueTableProperty qtable_prop;

AQQueueProperty queue_prop;

AQQueueTable q_table;

AQQueue queue;

AQAgent subs1, subs2;

try{

// Get session

if(aq_sess == null)

aq_sess = createSession();

// Create a AQQueueTable property object (payload type - TEXT):

qtable_prop = new AQQueueTableProperty("SYS.AQ$_JMS_TEXT_MESSAGE");

// Set multiconsumer flag to true:

qtable_prop.setMultiConsumer(true);

// Create a queue table called <topicName> in <username> schema: */

q_table = aq_sess.createQueueTable (username,topicName, qtable_prop);

// Create a new AQQueueProperty object:

queue_prop = new AQQueueProperty();

// Create a topic called <topicName>

queue = aq_sess.createQueue (q_table, topicName, queue_prop);

// Enable enqueue/dequeue on this queue:

queue.start();

System.out.println("Successful queue start");

}catch(AQException ex){

aq_sess = null;

ex.printStackTrace();

throw ex;

}finally{

aq_sess = null;

}

}
