I get a ClassCastException when attempting to send a MapMessage to a queue.
I'm running JBoss 4.0.0. The same code worked in JBoss 3.2.3.
| MapMessage message = queueSession.createMapMessage();
| for (Iterator iter = messageData.keySet().iterator(); iter.hasNext();)
| {
| String key = (String) iter.next();
| Object value = messageData.get(key);
| message.setObject(key, value);
| }
|
| queueSender.send(message);
|
The ClassCastException occurs on the "queueSender.send" line. See the stack
trace below.
