Does TOMCAT provide JDBC Connection Pooling ?
Tomcat (talking about version 3.x.x) is the reference implementation of the webapp part of J2EE (ie, no EJB). In this spec connection pooling is not contemplated.
You can however use pooling by using the JDBC 2.0 optional package instead of JDBC 2.0 directly.
[Also, http://www.javaexchange.com hosts a fine implementation of a JDBC Connection Pool. -Alex]
