Thanks, that is indeed the area that I have been looking at. While searching the archives I came across a message claiming that the Hypersonic database that comes included here is pretty weak and buggy, and recommends replacement with MySQL or even Oracle in a production environment. Should I be looking for a related issue happening here? This would be a lot more interesting and fun if I wasn't trying to make this work as a vendor for a client.
