This is one really trying my patience. I have a simple Spring 3.1 + Jersey application that I’m trying to work with ojdbc6.jar as my datasource. Unfortunately, no matter what I try, it can never find “oracle.jdbc.driver.OracleDriver” class.

I have turned on class loader tracing and I CAN SEE the ojdbc6.jar being loaded:

My jdbc.properties file:

jdbc.user="USER"/>
jdbc.password="password"/>

I’ve tried putting it in the WEB-INF/lib directory and in within Tomcat’s LIB directory. Both attempts have been in failure.

    Turns out that after a good night’s rest and some time away led me to this link here in SO. Turns out my jdbc.properties file was badly constructed for my Oracle instance but right for my Sybase one. Thanks to all for your help. Down voting me for being absurd.
