Is this expected, within a servlet, or is this just post hoc ergo propter hoc at it finest and I changed something else (wittingly or not). Same code outside of servlet does not need the forced loading of the class and the manual claims it's not need after java 1.6

I too am suspicious. But the vagaries of javax are daunting.
But if I comment it out, as just now, “No suitable driver found...”. I was days playing with configuration and such think that this very specific error message was telling me my CLASSPATH was wrong.
I wonder if I have an old javax installation (which I put in place just recently).
