Derby is really your only option.

With respect to other alternatives, I don't believe MySQL is "free" if =
you're=20

Of all of the "free" RDBMSs, Derby has the smallest footprint, and since =

of=20
application that you're attempting to build. You could use PostGress, =

need=20
or want.

The only caveat is your "good support" criteria.
"Good Support" is relative. You get what you pay for...

As I said, you're going to get a biased response.

I like others are looking at Derby from a similar perspective.

The only drawback is that Derby is under GPL. So as long as you follow =
GPL's=20
rules, you're ok.
