Never mind. I got the answer to my query on reading this excellent article :
http://www.ibm.com/developerworks/data/library/techarticle/dm-0502thalamati/index.html

The answer is that the desired database location needs to be specified in the database connection string.

As an aside, I would like to add that there is a dearth of good articles on Derby. It is just a candid opinion, and I don't intend to offend anyone, particularly those who are involved with this project.

Hi All,

My understanding is that restoring a backedup database should restore it to to its original location. If for example, a database is backedup from the location c:\one to c:\two, and if it is later restored, then the database ought to be restored to the original location, i.e. c:\one. However, I find that this is not the case with Derby. 

String connectionURL = "jdbc:derby:mydbname;restoreFrom=c:/temp/two/mydbname"

On using the above-mentioned connection string, the connection to the database is indeed made; however, it is not restored to its original location. Where the database is restored, and how I can get it restored to its original location?

Thanks in advance.

Regards,
Dinesh
