A servlet is a web application component. It is invoked when a web client makes 
a request. The client expects SOMETHING as a response from the server and, thus, 
from the servlet.

So, quitting with no response is not a good practice. What you should do is 
display an error page. There are several ways you can do it, 
"requestDispatcher.forward()" or throw an exception and have custom error pages
