Chapter 1. Introduction to Red Hat JBoss Web Server installation Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. Red Hat JBoss Web Server provides a fully supported implementation of the Apache Tomcat Servlet container and the Tomcat native library. Note If you need clustering or session replication support for Java applications, use Red Hat JBoss Enterprise Application Platform (JBoss EAP). 1.1. JBoss Web Server components JBoss Web Server includes components such as the Apache Tomcat Servlet container, Tomcat native library, Tomcat vault, mod_cluster library, Apache Portable Runtime (APR), and OpenSSL. Apache Tomcat Apache Tomcat is a servlet container in accordance with the Java Servlet Specification. JBoss Web Server 6.x contains Apache Tomcat 10.1. Tomcat native library The Tomcat native library improves Tomcat scalability, performance, and integration with native server technologies. Tomcat vault Tomcat vault is an extension for JBoss Web Server that is used for securely storing passwords and other sensitive information used by a JBoss Web Server. Mod_cluster The mod_cluster library enables communication between Apache Tomcat and the mod_proxy_cluster module of the Apache HTTP Server. 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 HTTP Connectors and Load Balancing Guide . Apache Portable Runtime The Apache Portable Runtime (APR) provides an OpenSSL-based TLS implementation for the HTTP connectors. OpenSSL OpenSSL is a software library that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. OpenSSL includes a basic cryptographic library. For a full list of components that Red Hat JBoss Web Server supports, see the JBoss Web Server Component Details page. 1.2. Differences between the Apache Tomcat distributions that Red Hat provides Both Red Hat JBoss Web Server and Red Hat Enterprise Linux (RHEL) provide separate distributions of Apache Tomcat. However, JBoss Web Server offers distinct benefits compared to the RHEL distribution of Apache Tomcat by including an integrated and certified set of additional components and features. JBoss Web Server also provides more frequent software and security updates. Note RHEL provides a distribution of Apache Tomcat on RHEL 7, RHEL 8.8 or later, and RHEL 9.2 or later only. For RHEL 8.0 through 8.7 and RHEL 9.0 through 9.1, the RHEL platform subscriptions do not provide a distribution of Apache Tomcat. On these operating system versions, JBoss Web Server is the only Apache Tomcat distribution that Red Hat provides, which is available as part of the Middleware Runtimes subscription. Apache Tomcat versions Consider the following version information for the Apache Tomcat distributions that are available with JBoss Web Server and RHEL: Apache Tomcat versions available with RHEL The RHEL 7 tomcat package is based on the community version of Apache Tomcat 7. The RHEL 8.x and RHEL 9.x tomcat package is based on the community version of Apache Tomcat 9. The tomcat package is available with RHEL 8.8 or later and RHEL 9.2 or later only. Apache Tomcat versions available with JBoss Web Server JBoss Web Server 3.1 provides a distribution of Apache Tomcat 7 and Apache Tomcat 8 together with an integrated and certified set of additional components and features. However, Red Hat no longer fully supports or maintains JBoss Web Server 3.1, which is currently in extended life cycle support (ELS) phase 2 with a planned end-of-life date of December 2028. JBoss Web Server 5.x provides a distribution of Apache Tomcat 9 that Red Hat fully tests and supports together with an integrated and certified set of additional components and features. Red Hat plans to end full support for JBoss Web Server 5.x on July 31, 2024. Red Hat will provide maintenance support until July 31, 2025 followed by extended life cycle support (ELS) phase 1 with a planned end-of-life date of July 2027. JBoss Web Server 6.x provides a distribution of Apache Tomcat 10.1 that Red Hat fully tests and supports together with an integrated and certified set of additional components and features. For more information about product life cycle phases and available support levels, see Life Cycle Phases . For more information about Apache Tomcat versions, see Apache Tomcat versions supported by Red Hat . Note Red Hat does not provide support for community releases of Apache Tomcat. Differences between JBoss Web Server and RHEL distributions of Apache Tomcat Consider the following differences between JBoss Web Server and the RHEL distribution of Apache Tomcat: JBoss Web Server RHEL distribution of Apache Tomcat Supports installation from archive files or RPM packages on RHEL versions 8 and 9. Note Red Hat does not provide a distribution of JBoss Web Server 6.x on RHEL 7. Supports installation from RPM packages only on RHEL 7, RHEL 8.8, and RHEL 9.2 or later. Supports installation from archive files on supported Windows Server platforms. Not applicable Offers developers support for creating and deploying back-end web applications and large-scale websites that can service client requests from Apache HTTP Server proxies in a secure and stable environment. Offers administrators support for deploying and running Apache Tomcat instances on a RHEL system. Provides a fully tested and supported distribution of Apache Tomcat that includes the following integrated and certified set of additional features and functionality: Fully tested and certified integration with the Apache HTTP Server for the forwarding and load-balancing of web client requests to back-end web applications by using a mod_proxy , mod_jk , or mod_proxy_cluster connector Tomcat native library for improving Apache Tomcat scalability, performance, and integration with native server technologies Tomcat Vault extension for masking passwords and other sensitive strings and securely storing sensitive information in an encrypted Java keystore Mod_cluster library for enabling communication and intelligent load-balancing of web traffic between the mod_proxy_cluster module of the Apache HTTP Server and back-end JBoss Web Server worker nodes Apache Portable Runtime (APR) library for providing an OpenSSL-based TLS implementation for the HTTP connectors Federal Information Processing Standards (FIPS) compliance Support for JBoss Web Server in Red Hat OpenShift environments JBoss Web Server Operator for managing OpenShift container images and for creating, configuring, managing, and seamlessly upgrading instances of web server applications in Red Hat OpenShift environments Automated installation of JBoss Web Server by using a Red Hat Ansible certified content collection Offers developers support for creating and deploying back-end web applications and large-scale websites that can service client requests from Apache HTTP Server proxies in a secure and stable environment Provides only a standard distribution of Apache Tomcat with infrequent software updates that is based on the community version. Provides a set of Maven repository artifacts in a jws-6. X . x -maven-repository.zip file that you can download from the Red Hat Customer Portal. You can use these artifacts in the web application archive (WAR) files for your application deployment projects. Not applicable Also includes libraries for embedded Tomcat in the jws-6. X . x -maven-repository.zip file, which enables you to build web applications by using embedded Tomcat with a fully supported Apache Tomcat version. Not applicable Differences between the JBoss Web Server and RHEL documentation sets The JBoss Web Server documentation set is broader and more comprehensive than the RHEL documentation for the tomcat package: JBoss Web Server includes a Red Hat JBoss Web Server 6.0. x Documentation archive file that contains API documentation for Apache Tomcat 10.1 and Tomcat Vault. You can download this archive file from the Red Hat Customer Portal . The JBoss Web Server product documentation page provides information on all of the following types of use cases: Performing a standard installation of JBoss Web Server from an archive file or RPM package on supported operating systems. Configuring JBoss Web Server for use with Apache HTTP Server connectors and load-balancers such as mod_jk and mod_proxy_cluster . Enabling automated installations of JBoss Web Server by using a Red Hat Ansible certified content collection. Using JBoss Web Server in a Red Hat OpenShift environment. Installing and using the JBoss Web Server Operator for OpenShift. Configuring JBoss Web Server to support features such as the HTTP/2 protocol, Tomcat Vault, and FIPS compliance. 1.3.
