For handling uncaught exceptions you can provide a new ThreadGroup which provides an implementation of ThreadGroup.uncaughtException(...). You can then catch any uncaught exceptions and handle them appropriately (e.g. send a crash log home).

Not sure if this is what you needing, but you can also detect if an exception has occurred from within your native code. See [http://java.sun.com/javase/6/docs/technotes/guides/jni/spec/functions.html#wp5234][1] for more info.

I wanted to accept both Free Wildebeest's and Orion Edwards' answers but it would not let me. The reason I wanted to do this is that I'd come to the conclusion that these were the two main ways to do it, but which one to chose depends on the individual case (mostly the size of the database). |

Depending on your library, you can usually just put both queries in one Command String, seperated by a semi-colon. |
