You can package a read-only Derby database into one of the jar files in your classpath, and access it using a different form of the connection URL. See: http://db.apache.org/derby/docs/10.8/devguide/cdevdvlp24155.html and http://db.apache.org/derby/docs/10.8/devguide/cdevdeploy11201.html#cdevdeploy11201

Sure it's possible, you can put your DB image into any JAR's classpath and access it using:

Class.getResourceAsStream()
