How to I get to Dubrovnik, Croatia from Austria/Italy? - croatia cruises

I am planning a trip to Europe and I can not find a simple way (I know that the cruise lines from Italy to Dubrovnik, Ancona go), but no way to Vienna, Austria to Dubrovnik. What would be the best way mate there and one night?
