I'm trying to run the JDBC examples (JdbcCheckup.java) 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 avail. As far as I can tell My classpath is correctly pointed to the zipfile. path=D:\oracle\ora81\jdbc\lib\classes12.zip. Can anyone offer any advice as to making these classes available?
