is your Driver loaded?

Are you using the <driver>oracle.jdbc.driver.OracleDriver</driver> tag
in the configuration?  Is the driver jar in the WEB-INF/lib directory?
Does the jar have a ".jar" extension?

The most common cause for this is that the server is not finding the
class.  Some Servlet Containers do not load jars that do not have the
".jar" interface.  You either need to place the driver jar in the
WEB-INF/lib directory or in $JAVA_HOME/jre/lib/ext directory.  You cannot
ever assume that classes loaded by the server are accessible by the webapps.
