what is catalina in tomcat server.

Answer Posted / raj

Catalina is the name of the servlet container of Apache
Tomcat since version 4.x. Tomcat implements Sun
Microsystems' specifications for servlet and JavaServer
Pages (JSP), which are important Java-based Web technologies.
Tomcat's servlet container was redesigned as Catalina in
Tomcat version 4.x.
other components of the Tomcat engine are:
* Tomcat Jasper which converts the code portions within
JavaServer Pages into servlets and pass them to Catalina to
process.
* Tomcat Coyote which is an HTTP connector based on
HTTP/1.1 specifications that receives and transmits web
requests to the Tomcat engine by listening to a TCP/IP port
and returns requests back to the requesting client.
