I'm using Oracle 9i and have no problems. I placed the oracle classes12.jar within the common/lib directory and use a resource description within the server.xml to identify the database where I store XML and other documents within a generic event logging framework with no problem.
Here are a few items to consider: 1. Do you have the correct jar file in common/lib 2. If using a Resource definition: is your resource configured with the proper class definition (e.g. <value>oracle.jdbc.driver.OracleDriver</value>) 2.1 Is the resource within the proper context (e.g. <Context path="/DBC_Logger" docBase="DBC_Logger.war"... <Resource name="jdbc/DBC_Logger" auth="Container" type="javax.sql.DataSource"/> ... <ResourceParams name="jdbc/DBC_Logger"> ... Hope this helps.
