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

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).
