NOTE: THIS PROJECT IS UNMAINTAINED
The canonical repository for this project is now hosted on Github (https://github.com/proxool/proxool) but even that hasn't been updated since 2011.
A Java SQL Driver that provides a connection pool wrapper around another Driver of your choice. Very simple to migrate existing code. Fully configurable. Fast, mature and robust. Transparently adds connection pooling to your existing JDBC driver.
Thanks for Proxool, it's the best!
