Thanks for this site. As someone who is trying to teach themselves JEE, this is really helpful.
I have followed the write your own code version of the HelloWorld tutorial, got it up and running, everything seems to be in order, but when it opens my browser (Firefox) the page that displays is an error message (see below). Obviously, since I’m working on a HelloWorld program, I’ve 0 experience to know where to look and how to debug. I’d be grateful for suggestions.
