1.2. Components
JBoss Enterprise Web Server consists of the following components:
- Apache Tomcat is a servlet container in accordance with Java Servlet Specification. JBoss Enterprise Web Server contains Apache Tomcat 6 and Apache Tomcat 7.
- Apache Native is a Tomcat library, which improves Tomcat scalability, performance, and integration with native server technologies. It also contains an implementation of APR (Apache Portable Runtime). APR is a binary protocol for communication of Apache HTTP Server and Apache Tomcat.
- Apache Tomcat Connectors (mod_jk, mod_cluster) are connectors between Apache HTTP Server and Apache Tomcat. Note that mod_cluster is a JBoss native load balancer and is more efficient, reliable, and scalable than mod_jk.
- Apache HTTP Server is an open-source web server developed by the Apache Software Foundation. The implementation follows the current HTTP standards.
