Chapter 1. Red Hat JBoss Web Server 5.7 Service Pack 2

Welcome to the Red Hat JBoss Web Server version 5.7 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 9.
  • 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 superior scalability, performance, and improved integration with native server technologies. APR is a highly portable library that is at the heart of Apache HTTP Server 2.x. It enables access to: advanced IO functionality such as sendfile, epoll and OpenSSL; functionality at the operating system level such as random number generation and system status; and native process handling such as shared memory, NT pipes and Unix sockets.
  • OpenSSL is a software library that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols and includes a basic cryptographic library.

This release of JBoss Web Server includes some moderate security updates.

JBoss Web Server 5.5 and later versions no longer provide OpenShift images based on Red Hat Enterprise Linux 7. This release of JBoss Web Server provides OpenShift images based on Red Hat Enterprise Linux 8.
