Using Derby with Java Web Start

[Néstor Boscán]

Hi
 
I need to create a standalone Swing application with an embedded database
that can be downloaded to 500 workstation using Java Web Start. I have the
following questions:
 
1.- Can I use Derby downloading it using Java Web Start?
2.- What happens when I download a new version of Deby? Will it upgrade my
database files automatically without ANY user intervention?
 
Regards,
