Java Servlets, Java Server Pages (JSP). Also Apache's Jakarta Project: Tomcat.

Java Servlets and JSPs

Java Servlets technology provides Web developers with a simple, consistent mechanism for extending the functionality of a Web server. A servlet can almost be thought of as an applet that runs on the server side.

JavaServer Pages (JSP) is a server-side technology that is an extension to the Java Servlet technology. JSPs have dynamic scripting capabililty that works in tandem with HTML code, separating the page logic from the static elements--the actual design and display of the page.

Tomcat
Tomcat Blue Reef makes Java Servlets and JSPs available on our Solaris Virtual Server via Tomcat, the flagship product of the Apache Jakarta Project. Tomcat is a world-class implementation of the Java Servlet 2.2 and Java Server Pages 1.1 Specifications.

If you wish to use Tomcat on your FreeBSD virtual server, you will need
download and install Tomcat yourself from Apache's web site.

Installation
For your Solaris-based virtual server, to configure your Apache Web Server to serve Java Servlets and JSPs, do the following.

Install Java (JDK 2).
Install the Jakarta Tomcat Server.

% vinstall tomcat

This is the Java Servlet engine. It knows how to parse JavaServer pages and Java Servlets. It runs a web server on port 8080 and has a special jserv-type protocol listening on 8007. It also has an enhanced and improved protocol listening on 8009, which is what mod_jk Apache Module talks to it on. The mod_jserv Apache Module talks on 8007.
Install the mod_jk Apache Module

For your FreeBSD-based virtual server, visit Apache's web site. Please note that Blue Reef will not provide technical assistance for Tomcat on the Free-BSD virtual servers:
