JDBC to oracle

I am trying to run the JDBC examples provided in the oracle/ora81/jdbc/demo/samples/oci8/basic-samples directory and the compiler cannot find the oracle.jdbc.driver package contained within the classes12.zip. I have also tried unzipping the file but to no progress. My classpath is correctly pointed to the zipfile. path=D:\oracle\ora81\jdbc\lib\classes12.zip.

Any advice pls
