It could be many things: the error message itself is in Chinese, and
it's in an image so there's no way for me to plug it into Google
Translate to see what it actually says.

My guess is that the client disconnected before you were able to send
the redirect, and so there's nowhere for the data to go -- that would
be a case where this exception is entirely expected and shouldn't be
considered a problem.

So, you're saying that Tomcat isn't running but it is somehow still
running? Can you be more specific? Why do you think it's running? Why
do you think it's not running?

By the way, you have code after your "sendRedirect" call that might
affect the response -- that's probably a bad idea. Generally, you want
"sendRedirect" to be the last thing your code does before returning
from the doGet (or functionally-equivalent) method.
