I wonder if if this configuration does the pooling correctly?

Here (http://activemq.apache.org/how-do-i-use-jms-efficiently.html) it
is suggested that "you can reuse the same MessageProducer for sending
messages to different destinations" which seems ok.
But I wonder if JmsTemplate is doing that correctly with the
org.jencks.amqpool.JcaPooledConnectionFactory? I thought that
JmsTemplate was creating a new producer/receiver each time, please
tell me I am wrong. If so, could I somehow configure that with JmsTemplate?

Hi,
I am using release 4.1.1 and I am wondering whether or not
TopicConnections are pooled automatically somehow.
No.
I have quite a lot TopicPublisher who publish to different topics.
Should I keep one TopicConnection open and use it for all
TopicSessions or should I open and close the connections each time?
http://activemq.apache.org/how-do-i-use-jms-efficiently.html
so typically use 1 connection and have a pool of consumers (maybe via
MDBs or Jencks or Springs MessageListenerContainers) then use a pool
of session/producers either through ActiveMQ's PooledConnectionFactory
with Spring's JmsTemplate or just use one producer and synchronize on
it
