Your understanding of the how Servlet Spec dictates servlet instance creation is incomplete. While n instances of a servlet *may* be created by the container, that's not required, and that's only one way to manage things. What Tomcat does is create one instance of each servlet for every <servlet> tag in your web.xml, and then a pool of threads which can use this servlet (aka the request processing threads). So even though your servlet doesn't implement SingleThreadModel (I hope, since that interface is gone, evil, and misleading), there's only one instance of it. And you're responsible for synchronization as needed for your domain-level objects and business processes.
