These links did not help me though. I think this is because I am on Windows XP, not Windows 7.
One thing I have noticed is that when I am getting that blank page, the Tomcat terminal receives all the html that I was supposed to get into my browser. As if the bug is that something tells Tomcat to send the html to the standard output instead of to the browser.
On the other hand, it might be doing this since it thinks it's some kind of an error output. I don't know since I cannot see the beginning of the html (it's too long).
