These release notes contain important information related to the Red Hat JBoss Web Server 3.1 Service Pack 4.

Welcome to the Red Hat JBoss Web Server version 3.1 Service Pack 4 release.

The JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It consists of:

  • Apache Tomcat: a servlet container in accordance with the Java Servlet Specification. JBoss Web Server contains Apache Tomcat 7 and Apache Tomcat 8.
  • The Apache Tomcat Native Library: a Tomcat library, which improves Tomcat scalability, performance, and integration with native server technologies.
  • The tomcat-vault: an extension for the JBoss Web Server used for securely storing passwords and other sensitive information used by a JBoss Web Server.
  • The mod_cluster library: a library that allows communication between Apache Tomcat and the Apache HTTP Server’s mod_proxy_cluster module. This allows the Apache HTTP Server to be used as a load balancer for JBoss Web Server.

Red Hat JBoss Web Server Service Pack 4

Service packs for Red Hat JBoss Web Server are produced when a set of critical bug fixes and/or security patches are required before a new full release.

These service pack releases reduce the number of individual patches that we produce and enable customers to keep up to date.

This update includes all fixes and changes from Red Hat JBoss Web Server 3.1 Service Pack 3.


From Red Hat JBoss Web Server 3.1 Service Pack 2, all the configuration files that were changed in the patch are appended by the suffix .zipnew to avoid overwriting existing configuration files.

If the new or changed properties or configuration options are applicable to you, you will need to manually add or define them in their respective property or configuration file.
