Package org.logicalcobwebs.proxool Description

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.

I want to add some better documentation right here. But in the meantime you should find comprehensive information on our web site

The latest version of this code is available from Sourceforge.

The majority of the work on Proxool (as of May 2002) was funded by Telenor Media AS
