Is it possible to run Java DB from read-only media in embedded mode?

I want to use Java DB in embedded mode in a Java application run开发者_如何学编程ning from a CD-ROM. Does anyone have any experience of doing this? Will it work? The database will only have selects issued against it.

This is possible: Deploying the database on the read-only media

Also I have noted select statements work when the database is owned by root with all write access withdrawn and is accessed by a non-privileged user.
