../common/lib is classes used for internal tomcat processes that need to be 
shared.  Try putting the JDBC driver in ../shared/lib

Tomcat V4.1.12

Trying to setup a connection pool to Oracle and get the following error:
java.sql.SQLException: Cannot load JDBC driver class 'null'

The Oracle classes12.jar file has been copied into ../common/lib  I checked
that the oracle.jdbc.driver.OracleDriver class specified in the server.xml
JDBC data resource is present in the jar file

Any ideas why Tomcat cannot find the JDBC driver ?

Thnaks for any help.
