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.

Chapter 1. Red Hat JBoss Web Server 6.1
Copy link

Welcome to the Red Hat JBoss Web Server version 6.1 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 introduces support for Windows Server 2022 and also includes some moderate security updates.

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

Red Hat JBoss Web Server 6.1 includes the following new features and enhancements.

2.1. Red Hat Enterprise Linux 10 support
Copy link

This release of JBoss Web Server is also certified for use on Red Hat Enterprise Linux 10. Support is available for installing JBoss Web Server on Red Hat Enterprise Linux 10 from an archive file or RPM packages.

2.2. Windows Server 2022 support
Copy link

This release of JBoss Web Server is also certified for use on Windows Server 2022. Support is available for installing JBoss Web Server on Windows Server 2022 from an archive file.

JBoss Web Server 6.1 introduces support for generating logs in JavaScript Object Notation (JSON) format. This feature uses JSON formatting to provide the same type of information as the one-line log format.

You can enable this feature in the JWS_HOME/tomcat/conf/logging.properties file in two ways:

  • If you want the catalina.out file for the console output log to be rendered in JSON format, set the java.util.logging.ConsoleHandler.formatter property to org.apache.juli.JsonFormatter.

    For example: 

    java.util.logging.ConsoleHandler.formatter = org.apache.juli.JsonFormatter

  • If you want the catalina.log file to be rendered in JSON format, set the 1catalina.org.apache.juli.AsyncFileHandler.formatter property to org.apache.juli.JsonFormatter.

    For example: 

    1catalina.org.apache.juli.AsyncFileHandler.formatter = org.apache.juli.JsonFormatter

For more information about org.apache.juli.JsonFormatter, see the Apache Tomcat documentation.

You can install the JBoss Web Server 6.1 on Red Hat Enterprise Linux or Windows Server. For more information see the following sections of the installation guide:
