I want to access an embedded database from the browser (using the embedded framework is valuable due to the size of the database). I see how to open a Bolt connector here (Bolt connector - Java Reference), but the example just shuts the database down immediately. What is the preferred way to keep the database open and listening so that I can interact with it from the browser? I've experimented with just putting a sleep call in the code to give me a few minutes and make sure it works, but what is recommended?
