Host: User-Agent: Mozilla/4.0 (compatible MSIE5.01 Windows NT) A service element may have several contexts.Ī typical Tomcat server configuration file (conf/server.xml) looks like this:

All the application assets, including the HTML, JSP, and servlets, are contained within the context.

ContextĬontext is used to represent a web application, which is typically packed as a web application archive (WAR) file. Clients use the hostname (e.g., to identify the application they want to reach. The engine element has one or more virtual hosts, each containing one web application. The host element is a virtual host that assigns a network name to a web application. The engine reads and compiles JSP files into Java servlet code, then displays HTML content to the clients. Requests for static pages are served using the server cache, whereas dynamic pages require JSP and servlet processing. A service element can only have one engine. The engine component processes all the incoming requests from one or more connectors, and generates the appropriate responses. HTTP connectors are used to connect with browsers and other web clients over HTTP, while AJP connectors are based on the Apache JServ Protocol (AJP), which allows Tomcat to talk to Apache web servers. There are two main types of connectors: HTTP connectors and AJP connectors. They are responsible for receiving requests, forwarding them to the relevant application, and then relaying the results to the requesting clients. ConnectorsĪs the name indicates, the connectors link Tomcat to the outside world. A Catalina server may have one or more service elements. Service elementĪ service element combines one or more connectors with a single engine. It encapsulates the entire Tomcat architecture, including the connectors, the service elements, the request-processing engine, and the web applications. 1: Tomcat architecture CatalinaĬatalina is the heart of the Tomcat server – its servlet container. It implements the Jakarta Servlet, Jakarta Expression Language, and Jakarta Server Pages (JSP) technologies and provides developers with a highly scalable, ready-to-use environment to house and deploy Java applications. What is Apache Tomcat and how does it work?Īpache Tomcat is an open-source web server and servlet container used to run Java-based HTTP applications.
