I put the code that opened the connection to the DB in a try/catch construct, and that worked fine if there was a problem with the DB (the catch clause displayed the exception using toString() so I could see what the problem was). However, at a later point the code tried to close the connection whether or not the open had succeeded, and that caused a NullPointerException in the case that the connection had failed. Going from memory, I think I fixed it by testing for null before closing the database connection.
