JBoss Enterprise Application Platform

The JBoss Enterprise Application Platform (or JBoss EAP) is a subscription-based/open-source Java EE-based application server runtime platform used for building, deploying, and hosting highly-transactional Java applications and services developed and maintained by Red Hat.^[1] The JBoss Enterprise Application Platform is part of Red Hat's Enterprise Middleware portfolio of software.^[2] Because it is Java-based, the JBoss application server operates across platforms; it is usable on any operating system that supports Java. JBoss Enterprise Application Platform was originally called JBoss and was developed by the eponymous company JBoss, acquired by Red Hat in 2006.^[3]

The GateIn project is a merge of JBoss Portal 2.7 and eXo Portal 2.5 that produced GateIn Portal 3.0, and also the related projects GateIn Portlet Container, eXo JCR, and JBoss Portlet Bridge.^{[21][22][23][24]}

• JBoss Enterprise Web Server (or JBoss EWS)
  This software is a platform for lightweight Java applications, but also handles large scale websites.^[25] JBoss EWS may be deployed as a standard enterprise web server, a simple Java application server, or an enterprise open source application infrastructure.^[26]
  Key components:
  • Apache Tomcat – including Java Servlet and JavaServer Pages
  • Apache Web Server – including common modules and connectors for authentication, caching, proxying, filtering, and load balancing (mod jk)

Lists of components^[27] and standards supported^[28] are available.

• JBoss Web Framework Kit
  This software is a set of web frameworks used for building light and rich Java applications.
  Components:^[29]
  • Google Web Toolkit – framework for rich Internet applications
  • RichFaces – framework for rich Internet applications
  • Spring Framework – Java framework
  • Apache Struts – Java framework
• JBoss Cache (or JBC)
  This software implements a cache for frequently accessed Java objects to improve application performance. The cache can be replicated and transactional. The cache can be replicated across one or more Java Virtual Machines (JVM) across a network. The cache can be transactional because a JTA compliant transaction manager can be configured and make any cache interaction transactional. The two types of JBoss Cache are Core and POJO, with the POJO library built on top the Core library.^[30]
• JBoss Netty
  This software is a New I/O (NIO) client-server framework for the development of Java network applications such as protocol servers and clients. The asynchronous event-driven network application framework and tools is used to simplify network programming such as TCP and UDP socket servers.^[31] Netty includes an implementation of the reactor pattern of programming.
