trouble with apache derby embedded datasource

I'm trying to create an Apache Derby Embedded data source on a Mac. I'm actually trying to install the database provided with the Adobe ColdFusion 9 Getting Started book. I have the datasource in the db folder, but I continue to receive this error:

Connection verification failed for data source: ows

org.apache.derby.impl.jdbc.EmbedSQLException: Database '/Applications/ColdFusion9/db/ows/' not found.

The root cause was that: java.sql.SQLException: Database '/Applications/ColdFusion9/db/ows/' not found.

Does the datasource go into another folder than db on Mac? Thanks for any help.
