AMQPool

AMQPool

Jencks contains an JMS pooled ConnectionFactory specific for ActiveMQ. The main difference with the ActiveMQ provided one is that it plays nicely in a transacted environment (XA or JCA) and can also have better performances in some cases (see this blog).

This connection pool comes with three spring factories:

Note that you always use a JcaPooledConnectionFactory if you prefer.
