Found this site which lists almost all the possible connection strings for almost every database.
http://www.connectionstrings.com
This is an excerpt from the site itself which says :-
Today there are 213 connection strings in the database which have been collected from other internet sites, books, help files, msdn etc or have been submitted by fellow developers from all around the world.

Pretty MS centric site. Looked for a number of JDBC connection strings and found none for SQL Server or Oracle. Also, no connect string for Derby.
