The wait is over: JBoss Web Server 5 with Tomcat 9 is here!

We are excited to announce the general availability of Red Hat JBoss Web Server 5.0 for Red Hat Enterprise Linux and the technology preview of transactions processing with Narayana. JWS 5 is available through zip, RPM, Maven repository, and the Red Hat Container Catalog.

Red Hat JBoss Web Server combines market-leading open source technologies with enterprise capabilities to provide a single solution for large-scale websites and lightweight web applications. It combines the world’s most deployed web server (Apache) with the top servlet engine (Tomcat) and excellent support for middleware (ours).

Main Components

  • Apache Tomcat

    • A servlet container in accordance with the Java Servlet Specification. JBoss Web Server contains Apache Tomcat 9.


  • 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.
