We are excited to announce the General Availability release of Red Hat JBoss Web Server 5.0 for Red Hat Enterprise Linux (RHEL). Other platforms are will be released shortly. This release includes a technology preview of transactions processing through Narayana. JBoss Web Server 5 is available in the ZIP or RPM format from the JBoss Web Server 5.0 Maven repository and Container Catalog.
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 the best support in middleware (from Red Hat).
Main Components
-
Apache Tomcat 9
- 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
