Looks like J.Bean didn't read the errata. Strange, though, my copy had some errors and not others. Protocol & Content handler stuff is a godsend. Sure can't figure out that stuff from the JavaDoc. I agree that the Security section (and mention of signed applets) might need to be updated in a future version, but it's a big ball of twine at the moment. (Java Plugin 1.2.2 has cleaned things up a bit, but only if you pay $$$ for a certificate.)
