Ok, Chris -- good news and bad news for me, I suppose. I made a sole reference to the driver source in a standalone JSP, which could hit it, so we know the driver is good and valid.
It's just that it's being refused in the DBCP setting within the context.xml file in the META-INF fldr, as well as whether I not I put the resource ref in the web.xml file of the webapp folder. That tells me my Oracle jar file works fine, and driver. Just got to shore up the conn pool part now.

When this happens to people, I usually recommend: 1. Quadruple-check that you have your JDBC driver only in one place (in Tomcat's /lib directory) 2. Remove all unnecessary configuration from your <Resource> element: just (simple) URL, driver class, username and password, just to get things started. Good luck, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkuG7toACgkQ9CaO5/Lv0PD/YACgu9h3NO6F8HRwRj8F1k9CRYu/ s4oAnirBRqqMw0S3GYByn6GzHLiRwug5 =9Mzd -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
