Reference previous post, the servlet compiles fine.
Possibility 1, a bug in the browser.
Possibility 2, your servlet or jsp is looping, the browser
crashes because it can't cope with the volume of html returned.
Possiblity 3, you aren't closing tags somewhere, which produces a "stack overflow error" in the browser's parser.
Have you tried using wget to get the html produced by your page, or a different browser?
