Figure 3: Interoperation Client / Web Server / Servlet Container 

3.1.2  The Servlet Container 

The Servlet Container, as illustrated by Figure 3, receives the HTTP request for a dynamic page 

from the Web server, and is then responsible for invoking the servlet and returning the 

generated response to the Web server. Exactly how the Servlet Container processes the 

requests can vary from implementation to implementation. However, an efficient and therefore 

common implementation of a Servlet Container is shown in Figure 4.
