There is no "official" Java way to do this AFAIK.

The way I usually hunt for it is to use find and jar to look through all jar files in a given tree.

./v2.6.1/lib/csw_library.jar
./v2.6.1/lib/oracle_drivers_12_01.jar
oracle/sql/BLOB.class

If you're on Windows and don't want to install Cygwin, then I suppose you would have to write a batch script to locate the jar files.
