Proxool is a Java connection pool. It's not rocket science but we've been doing it since 2001 and we've ironed out a lot of problems. Development has slowed down considerably over the past few years but we're still here, making releases and answering support questions.


Transparency: Transparently adds connection pooling to your existing JDBC driver.

Open Source: Our licence allows you flexibility to use it in both commerical and other open source products.

Standards: Complies with the J2SE API, giving you the confidence to develop to standards.

Control: You can monitor the performance of your database connections and listen to connection events

Ease of use: It's easy to configure using the JDBC API, XML, or Java property files - you decide.


23 August 2008 - 0.9.1. Fix to include proxool-cglib.jar in the binary release. This file is a repackaged version of CGlib 2.1.3. See the change log for details.

19 August 2008 - 0.9.0. Finally. See the change log for details.

10 January 2007 - 0.9.0RC3. Getting close to a 0.9.0 release. This wraps up some fixes for the packaging of Cglib, more flexibility when shutting down, a missing property when configuring as a datasource. See the change log for details.

23 March 2006 - 0.9.0RC2. Only a few changes since RC1, but the most important is our upgrade to Cglib 2.1_3. With the use of Jar Jar Links we can now keep up to date very easily. See the change log for details.

2 March 2006 - 0.9.0RC1. 810 days. What a long gap between releases! 0.9.0 has been in the pipeline for many months now and a considerable amount of work was put in during 2004 and, to a lesser extent, 2005. Unfortunately, we let things slip and this release is well overdue. Thank you to all the people who continue to use Proxool and tell us so. There are no known problems with this release but, as ever, you should remember that it is only a release candidate. The latest stable release remains 0.8.3. See the change log for details.

14 December 2003 - 0.8.3 Changes to allow Proxool to work with Cglib 2.0. If you upgraded to Hibernate 2.1 then you will need to upgrade to Proxool 0.8.3. See the change log for details.

Older news

Which JDK?

Proxool is fully compatible with JDKs 1.2 to 1.5. Our tests with early releases of JDK 1.6 show no problems.

New: As of 0.8.0, because of the use of Cglib's proxy library, we are now able to support all JDKs from 1.2 upwards.
