Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Welcome to the Red Hat JBoss Web Server version 6.1 Service Pack 2 release.

Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It consists of an application server (Apache Tomcat servlet container) and the Apache Tomcat Native Library.

JBoss Web Server includes the following key components:

  • Apache Tomcat is a servlet container in accordance with the Java Servlet Specification. JBoss Web Server contains Apache Tomcat 10.1.
  • The Apache Tomcat Native Library improves Tomcat scalability, performance, and integration with native server technologies.
  • Tomcat-vault is an extension for the JBoss Web Server that is used for securely storing passwords and other sensitive information used by a JBoss Web Server.
  • The mod_cluster library enables communication between JBoss Web Server and the Apache HTTP Server mod_proxy_cluster module. The mod_cluster library enables you to use the Apache HTTP Server as a load balancer for JBoss Web Server. For more information about configuring mod_cluster, or for information about installing and configuring alternative load balancers such as mod_jk and mod_proxy, see the Apache HTTP Server Connectors and Load Balancing Guide.
  • Apache portable runtime (APR) is a runtime that provides an OpenSSL-based TLS implementation for the HTTP connectors. JBoss Web Server provides a distribution of APR for supported Windows platforms only. For Red Hat Enterprise Linux, you can use the APR package that the operating system provides.
  • OpenSSL is a software library that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols and includes a basic cryptographic library. JBoss Web Server provides a distribution of OpenSSL for supported Windows platforms only. For Red Hat Enterprise Linux, you can use the OpenSSL package that the operating system provides.

This release of JBoss Web Server includes an important security update.

This release of JBoss Web Server provides OpenShift images based on Red Hat Enterprise Linux 8.
