Hello
I have written a MVC2 : DAO program using an Apache derby embedded DB.
Currently I have not been able to jar the program : runs in IDE.
My question concerns running this program on multiple work stations of a local network. Will this be possible?
Currently when I run it in the IDE it will only allow one connection. Could someone explain the basics of what it would take to run this program on a network?
