I still think it is possible to "run as user". If you are interested, I could show you a simple demo of how it works. Please contact me directly on my email..

Whoops, I meant Winstone or Jetty. Derby (database engine written in Java) is a completely different ball of wax.

Even I would love to have Java Servlet support. Setting up one of the enterprise grade servlet containers might be difficult. But, a small one like Winstone or even Derby is very very easy. Please consider adding this support. I need it for my application. I can help you set it up too.
