Chapter 1. Overview

AMQ JMS Pool is a library that provides caching of JMS connections, sessions, and message producers. It enables reuse of connection resources beyond the standard lifecycle defined by the JMS API.

AMQ JMS Pool operates as a standard JMS ConnectionFactory instance that wraps the ConnectionFactory of your chosen JMS provider and manages the lifetime of Connection objects from that provider based on the configuration of the JMS pool. It can be configured to share one or more connections among callers to the pool createConnection() methods.

AMQ JMS Pool is part of AMQ Clients, a suite of messaging libraries supporting multiple languages and platforms. For an overview of the clients, see AMQ Clients Overview. For information about this release, see AMQ Clients 2.10 Release Notes.

AMQ JMS Pool is based on the Pooled JMS messaging library.
