[Baypiggies] Need help root causing exception http.client.BadStatusLine

[AM]

I think what Guido meant was that the server was alive but did not 
respond with anything, instead closing the connection.

Assuming you are running on linux or OSX a quick way to check it is to 
use the netcat tool in a terminal:

nc -l -p 8080

Then have your client connect to localhost:8080/...

In the terminal you should see the request. Ctrl-C netcat and you should 
(afaik) see the BadStatusLine error.

What that would mean is that somewhere tomcat decided to simply close 
the connection before any response was sent out.
