Accessing databases within a jar file using the classpath/modulepath Once an archive containing one or more databases has been created it can be placed in the classpath/modulepath. This allows access to a database from within an application without the application's knowing the path of the archive. Accessing read-only databases from classpath Read-only databasesputting in classpath

When jar or zip files are part of the classpath/modulepath, you specify the classpath subsubprotocol instead of the jar subsubprotocol to connect to them.

To access a database in a zip or jar file in the classpath/modulepath:

Set the classpath/modulepath to include the jar or zip file before starting up :CLASSPATH="C:\dbs.jar;%CLASSPATH%" Connect to a database within the jar or zip file with the following connection URL: jdbc:derby:classpath:databasePathWithinArchive

For example:

jdbc:derby:classpath:products/boiledfood
