Using the embedded driver I can connect to my derby database using the JDBC url:
jdbc:derby:mydbname
But, I usually put the full path for the db like:
jdbc:derby:/Users/oreyes/dbs/mydbname
Is there a way I can just specify the db name and have something like a "db_path" or something like that?
I'm not an expert with derby, setting derby.system.home as described in developers guide seems to work as you expect.
