From what I understand,
$ORACLE_HOME/jdbc/lib/classes12.jar is for JDK 1.3 and earlier $ORACLE_HOME/jdbc/lib/ojdbc14.jar is required for JDK 1.4
We've found that you can get by with the classes12.jar on Oracle 9i (this was on Gentoo and RedHat) even with JDK 1.4, but in the move up to Oracle 10g it seems more crucial.
Also there were some docs by Oracle (still trying to find it) where they suggested using "oracle.jdbc.OracleDriver" instead of "oracle.jdbc.driver.OracleDriver" as of the move to 10g. During tests, we found instances in our code where that appears to make a important different -- but that was fairly esoteric code, such as proxy users.

There is definitely more than just a name change between class12.jar and ojdbc14.jar. I think the former follows JDBC 1.2 spec and the latter follows JDBC 1.4 spec. I'm not sure what exactly the changes are but I remember reading something in Oracle.com that said there was a difference.
