Chapter 1. Introduction
1.1. About Red Hat JBoss Web Server
The JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It consists of:
- Apache Tomcat: a servlet container in accordance with the Java Servlet Specification. JBoss Web Server contains Apache Tomcat 9.
- The Apache Tomcat Native Library: a Tomcat library, which improves Tomcat scalability, performance, and integration with native server technologies.
- The tomcat-vault: an extension for the JBoss Web Server used for securely storing passwords and other sensitive information used by a JBoss Web Server.
- The mod_cluster library: a library that allows communication between Apache Tomcat and the Apache HTTP Server’s mod_proxy_cluster module. This allows the Apache HTTP Server to be used as a load balancer for JBoss Web Server. For information on the configuration of mod_cluster, or for information on the installation and configuration of the alternative load balancers mod_jk and mod_proxy, see the HTTP Connectors and Load Balancing Guide.
- If you need clustering or session replication support for Java applications, Red Hat recommends that you use Red Hat JBoss Enterprise Application Platform (JBoss EAP).
