Any alternative to c3p0 connection pool library

I am currently using c3p0 library to connect to MySQL using Hibernate. Any other alternative available for free?

there is the commons-dbcp. this is usually bundled in tomcat servers. but is its own project. the 1.4 series supports JDBC 4 features.

4 most popular and widely used open source connection pool libraries are available in Java. http://www.findbestopensource.com/ta...onnection-pool
