Yes, I agree that the above is much cleaner. In my example, I was using
the Java database connectivity classes directly. Since I only have to
use a subset of the available Java SQL classes and methods, I wrote a
simple Faï¿½ade for the classes and methods I needed. This ensures that
only the most necessary objects are created in IDL and simplifies the
access overall. I can definitely see myself using the Faï¿½ade pattern
quite a bit in the coming days....
