JSP Tag library pooling - Each tag markup in JSP file is handled by a tag handler class. At runtime, Jasper detects changes to JSP files and recompiles them. Jasper parses JSP files to compile them into Java code as servlets (that can be handled by Catalina). Tomcat 5.x uses Jasper 2, which is an implementation of the Sun Microsystems's JavaServer Pages 2.0 specification. Coyote listens for incoming connections on a specific TCP port on the server and forwards the request to the Tomcat Engine to process the request and send back a response to the requesting client. CoyoteĬoyote is Tomcat's HTTP Connector component that supports the HTTP 1.1 protocol for the web server or application container. Different implementations of Realm allow Catalina to be integrated into environments where such authentication information is already being created and maintained, and then use that information to implement Container Managed Security as described in the Servlet Specification. In Tomcat, a Realm element represents a "database" of usernames, passwords, and roles (similar to Unix groups) assigned to those users. Catalina implements Sun Microsystems' specifications for servlet and JavaServer Pages (JSP). Core Components CatalinaĬatalina is Tomcat's servlet container. Tomcat requires a Java Runtime Enterprise Environment that conforms to JRE 1.1 or later. Tomcat can be used as either a standalone product with its own internal Web server or together with other Web servers, including Apache, Netscape Enterprise Server, Microsoft Internet Information Server (IIS), and Microsoft Personal Web Server.
Described as a "reference implementation" of the Java Servlet and the Java Server Page specifications, Tomcat is the result of an open collaboration of developers and is available from the Apache Web site in both binary and source versions.

Tomcat is an application server from the Apache Software Foundation that executes Java servlets and renders Web pages that include Java Server Page coding.
