The openacs package acs-content-repository uses some java utility procs when running on oracle. It should have called the file packages/acs-content-repository/java/Util-oracle.sqlj upon installation of openacs. Maybe that failed because java is not set up correctly on your oracle installation - I think there are some options regarding java support that should not be unchecked or something like that (haven't looked into the installation guide for some time).
