NullPointerException in the HTTP Example

[Richard Jackson]

I just copied the example code into my own package and commented out
the cookie stuff because I don't need it for what I'm doing right now.
I'm just using it to verify that I have started/shut down my server
correctly. Once I have that done then I will be replacing it any ways
with a servletHandler I will be writing.
