Wildfly – flexible, lightweight, managed application runtime

Last Updated on July 13, 2021

Wildfly (was JBoss Application Server) is a J2EE certified platform for developing and deploying enterprise Java applications, Web applications, and Portals. Wildfly provides the full range of J2EE 1.4 features as well as extended enterprise services including clustering, caching, and persistence.

Wildfly includes support for Enterprise Java Beans (EJB) 3.0 which is designed to dramatically simplify the enterprise Java programming model.

Wildfly is the number one most widely used Java application server on the market. Hundreds of professional open source developers have contributed to Wildfly. In fact all JBoss employed contributors to the Wildfly were hired from the community and each of them contributed to an open source project in one way or another.

Features include:

  • Aspect-oriented programming (AOP) support.
  • Clustering.
  • Deployment API.
  • Distributed caching (using JBoss Cache, a standalone product).
  • Distributed deployment (farming).
  • Enterprise JavaBeans versions 3 and 2.1.
  • Failover (including sessions).
  • Hibernate integration (for persistence programming; Java Persistence API or JPA).
  • Java Authentication and Authorization Service (JAAS).
  • Java EE Connector Architecture (JCA) integration.
  • Java Management Extensions.
  • Java Server Pages (JSP) / Java Servlet 2.1/2.5 (Tomcat).
  • JBossWS (JBoss Web Services) for Java EE web services like JAX-WS.
  • JDBC.
  • Load balancing.
  • Management API.
  • OSGi framework.
  • RMI-IIOP (JacORB, contraction of Java and CORBA).
  • SOAP with Attachments API for Java (SAAJ).
  • Teiid data virtualization system.
  • JBoss EJB3 included with JBoss 5 provides the implementation of the latest revision of the Enterprise Java Beans (EJB) specification. EJB 3.0 is a deep overhaul and simplification of the EJB specification. EJB 3.0’s goals are to simplify development, facilitate a test driven approach, and focus more on writing plain old java objects (POJOs) rather than coding against complex EJB APIs.
  • JBoss Messaging is a high performance JMS provider in the JBoss Enterprise Middleware Stack (JEMS), included with JBoss 5 as the default messaging provider. It is also the backbone of the JBoss ESB infrastructure. JBoss Messaging is a complete rewrite of JBossMQ, which is the default JMS provider for the JBoss AS 4.x series.
  • JBossCache 2.0 that comes in two flavors. A traditional tree-structured node-based cache and a PojoCache, an in-memory, transactional, and replicated cache system that allows users to operate on simple POJOs transparently without active user management of either replication or persistency aspects.
  • JBossWS 2 is the web services stack for JBoss 5 providing Java EE compatible web services, JAXWS-2.0.
  • JBoss Transactions is the default transaction manager for JBoss 5. JBoss Transactions is founded on industry proven technology and 18 year history as a leader in distributed transactions.
  • JBoss Web is the Web container in JBoss 5, an implementation based on Apache Tomcat that includes the Apache Portable Runtime (APR) and Tomcat native technologies to achieve scalability and performance characteristics that match and exceed the Apache Http server.
