Oracle has changed the driver class for version 1.1x to 1.2. In 1.1x it was oracle.jdbc.driver.OracleDriver while in 1.2 is oracle.jdbc.OracleDriver - so use the driver depending upon the version you are using (you can unjar/unzip and you'd find what class you really have).

RE: Tomcat 4.1, DBCP and Oracle
Yes, I have been able to do that. When you say that Tomcat doesn't automatically recognize the file in its classpath, how do you know that? And when you hard code it in /bin/setclasspath.sh and it sees it, does your DataSource config now work? If not, then there is a config problem. You'll have to post your configuration in order to flesh that issue out. One hint, make sure to use username and not user for DBCP configuration. Attached is the DBCP config I use for your reference.

RE: Tomcat 4.1, DBCP and Oracle
Sounds as if you don't have the class that it says you don't have. You need to load in the appropriate JDBC driver class. Have you just loaded the standard version of JDBC?

1. Rename classes12.zip to classes12.jar. You don't have to repackage the classes, simply rename the file. 2. Put classes12.jar in CATALINA_HOME/common/lib.

Did you configure Oracle DataSource thru the web interface of Admin app in Tomcat 4.1? If you did, you will need to link the Global datasource to your webapp in server.xml.
