Changing Message Selector fails
Hi,
I have two brokers B1 and B2. Producer P1 connected to B1 and B2 added to
B1 as network connector. As per my requirement I will be changing the
selector dynamically. The following code is written to change the selector
for Consumer.
public void changeMessageSelector(String filter)
{
if( filter != null )
try
{
if (consumer != null)
{
MessageConsumer consumerNew =
session.createConsumer(topic, filter);
consumerNew.setMessageListener(this);
consumer.close();
consumer = consumerNew;
if (LogClient.isFinerAllowed)
{
_logger.finer("Message Selector Changed to
"+filter);
}
}
}
catch (JMSException e)
{
_logger.log(Level.SEVERE, "Failed to change Message
Selector, Exception", e);
}
else
{
_logger.severe("NULL Message Selector is passed");
}
}
Consumber C1 connected to broker B1 then everything is working I am able
to change the selector dynamically and getting all the message published by
P1.
But if Consumer C2 connected to B2 then when ever I try to change the
selector I am getting the following error message and broker stop reporting
new messages.
