The PoolMan library and virtual JDBC2.0 driver provide Java object pooling, with particular extensions for database resources and caching SQL queries/results across multiple databases. PoolMan eliminates a common bottleneck in enterprise apps and maximizes JDBC performance for servlets, Java Server Pages, and other Java database applications.

Release Notes: Some memory leaks were repaired. Handling of the unlocked-locked object transitions was also repaired. An additional ClassLoader fix which is relevant in deployment scenarios that require use of the System ClassLoader was added. The ability to retrieve the raw physical connection through the DataSource client-side handle was added.
Release Notes: JMX is optional, which circumvents occasional ClassLoader problems that pop up when used with Tomcat and JUnit. Improved performance of pool requests/responses, fixes for metadata and object return notification that were skewing the number of unavailable objects, a couple of new optional elements to the XML config, and a handful of minor additional bugfixes.
Release Notes: A synchronization issue with the thread that automatically returns lost and timed-out objects to their pools has been fixed. A new ResultSetMetaData implementation that corrects problems with several drivers has been added, as well as new configurable elements to handle super heavy load and validation. There are various other minor fixes.
Release Notes: Fixes for a ClassLoader problem causing InstanceAlreadyExists errors which made its appear as if PoolMan couldn't locate your pool in the XML, and a new third-party JAR required for installation.
Release Notes: This release rearchitects the internal frameworks to integrate JMX-based management and the Web admin agent for pools, replaces metadata with XML representation, and adds tons of parameters, new docs, a new Web app, and many bugfixes.
