Thanks Antonio Now I can make it connected.
By the way, can I say that, if I use <data-source> in my struts application, then the struts servlet manages the connection? That is, when the application is deployed, the struts servlet will automaticly create connections of numbers specified by "minCount". And the application just fetch the connection created to use?
