                         java.lang.ClassNotFoundException

Constructs a connection pool. Makes sure only one is active at one time in a ClassLoader context. When a new connection pool is created, all the instances created before it are deactivated. Upon deactivation, instances close their connections with the database and so cannot be used anymore. Any attempt to use a deactivated connection pool results in an internal error.
