Erm.... if he weren't importing those packages, his code wouldn't
compile. The OP has a problem with /configuration/:

Something is wrong in here:

>>> <Resource
>>> name="jdbc/test" auth="Container"
>>> type="oracle.jdbc.pool.OracleConnectionPoolDataSource"

I wonder if Tomcat doesn't really know what to do with this "type". Why
do you want to use the OracleConnectionPoolDataSource specifically?

>>> driverClassName="oracle.jdbc.pool.OracleConnectionPoolDataSource"

This is probably wrong. This class is the same as the one you used for
"type", which probably extends javax.sql.DataSource. You want something
that implements java.sql.Driver. Re-check the Oracle documentation to
see what driver class you should really be using.
