I think its better to direct these questions to the dbcp guys; dbcp is, as is usual for Jakarta stuff, extremely undocumented - but _someone_ must know the answers to these questions.
I *don't*; I've ALWAYS used an appserver datasource in production. If you can't get definitive answers from dbcp guys, try out c3p0 or proxool. I *know* that Steve Waldman will support c3p0 properly. > Connections only time out late at night or over the weekend when the web > app in question is not being used. > > Normally, the web app is used heavily during the day until about 9pm and > then no more until the next day. > > I want to take advantage of pooling with Hibernate when the app is being > used heavily, but i do not want it to drop the connection afterwards > when it is idle. > > I simply would like some good docs for how to properly set up DBCP with > Hibernate and the validation query.
