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.
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 Copy linkLink copied to clipboard!
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_clusterlibrary enables communication between Apache Tomcat and themod_proxy_clustermodule of the Apache HTTP Server. Themod_clusterlibrary enables you to use the Apache HTTP Server as a load balancer for JBoss Web Server. For more information about configuringmod_cluster, or for information about installing and configuring alternative load balancers such asmod_jkandmod_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.

1.2. Differences between the Apache Tomcat distributions that Red Hat provides Copy linkLink copied to clipboard!
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.
RHEL provides a distribution of Apache Tomcat on RHEL 7, RHEL 8.8 or later, RHEL 9.2 or later, and RHEL 10.
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.
1.2.1. Apache Tomcat versions Copy linkLink copied to clipboard!
Consider the following version information for the Apache Tomcat distributions that are available with JBoss Web Server and RHEL:
| Apache Tomcat version | JBoss Web Server distribution | RHEL distribution |
|---|---|---|
| Apache Tomcat 7 | 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.
Note: |
The RHEL 7 |
| Apache Tomcat 8 | 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.
Note: | Not applicable |
| Apache Tomcat 9 | JBoss Web Server 5.x provides a distribution of Apache Tomcat 9 together with an integrated and certified set of additional components and features.
Note: |
The RHEL 8.x and RHEL 9.x
The RHEL 10 |
| Apache Tomcat 10 | 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. |

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, 9, and 10.
Note: | Supports installation from RPM packages only on RHEL 7, RHEL 8.8 or later, RHEL 9.2 or later, and RHEL 10.
Note: |

1.2.3. Differences between the JBoss Web Server and RHEL documentation sets Copy linkLink copied to clipboard!
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 6.1.x Documentationarchive 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_jkandmod_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. JBoss Web Server operating systems and configurations Copy linkLink copied to clipboard!
Red Hat JBoss Web Server supports different versions of the Red Hat Enterprise Linux and Windows Server operating systems. For more information about supported operating system versions, see JBoss Web Server 6 Supported Configurations.
1.4. JBoss Web Server installation methods Copy linkLink copied to clipboard!
You can install Red Hat JBoss Web Server on supported Red Hat Enterprise Linux and Windows Server systems by using archive installation files that are available for each platform. You can also install JBoss Web Server on supported Red Hat Enterprise Linux systems by using RPM packages.
The following components are included in the archive installation files. These components are the core parts of a JBoss Web Server installation.
