Subject RE: Tomcat 3.3 and Oracle9i
Date Fri, 20 Dec 2002 22:37:44 GMT

Oracle 8 jar doesn't work with oracle 9.. Connections will always
fail until you either patch your or get the ojdbc14.jar
Drivers from oracle.

Obviously, Tomcat 3.3 hasn't changed ;-).  I can't see any reason why
replacing the "Oracle 8" jar with the "Oracle 9" jar wouldn't work.  If
you can post more information on your config (e.g. where the Oracle jar
is located), and any errors in the logs, it would help the list to help
you :).
