A DataSourcePool listener which allows you to hook on the borrow/return process of getting or returning connections from the pool. 

In the configuration use the poolListener key to configure which listener to
use.




Example: datasource.ora10.poolListener=my.very.fancy.PoolListener





 Notice: This listener only works if you are using the default Avaje DataSourcePool.
