Apache Tomcat is the reference implementation for the Java Servlet and JavaServer Pages (JSP) specification from the Apache Jakarta project. . This package contains an Apache 1.3 module (mod_jk) to forward requests from Apache to Tomcat using the AJP 1.3 or 1.4 protocol. It can either talk to Tomcat on the local machine or to a remote engine using TCP. . For more information about Tomcat please take a look at the home page at http://jakarta.apache.org/tomcat/index.html.
