In the Tomcat world, a Server represents the whole container. Tomcat provides a default implementation of the Server interface., and this is rarely customized by users... An Engine represents request processing pipeline for a specific Service. As a Service may have multiple Connectors, the Engine received and processes all requests from these connectors, handing the response back to the appropriate connector for transmission to the client. The Engine interface may be implemented to supply custom Engines, though this is uncommon... This manual is a primer covering the basic steps of using Tomcat to set up a development environment, organize your source code, and then build and test your application. It does not discuss architectures or recommended coding practices for web application development, or provide in depth instructions on operating the development tools that are discussed. References to sources of additional information are included in the following subsections.
