问题
I have developed an application with derby db. I have created DB in my system. I need to deliver the application along with the db. I have deleted all the data from tables. Only the tables(structure with empty data) are remaining. So If I copy the db files (log,seg0,tmp,db.lck,service.properties all these in a single folder) to another system, will it work fine..?

Yes, it will work fine, although for the cleanest flow you should ensure that no application is accessing the database at the time that you copy the database folder.
From the Derby docs: http://db.apache.org/derby/docs/10.10/getstart/cgsintro.html
The on-disk database format used by Derby is portable and platform-independent. You can move Derby databases from machine to machine without needing to modify the data. A Derby application can include a pre-built, populated database if it needs to, and that database will work in any Derby configuration.
For more information about packaging a database with your application, see: http://db.apache.org/derby/docs/10.10/devguide/cdevdeploy32171.html
