JBoss Application Server (or JBoss AS) is a free software/open-source Java EE-based application server.
JBoss application server operates cross-platform: usable on any operating system that supports Java.
JBoss AS was developed by JBoss, now a division of Red Hat.

JBoss AS 4.0, a Java EE 1.4 application server, features an embedded Apache Tomcat 5.5 servlet container. It supports any Java Virtual Machine between versions 1.4 and 1.6.
JBoss can run on numerous operating systems including many POSIX platforms (like GNU/Linux, FreeBSD and Mac OS X), Microsoft Windows and others, as long as a suitable JVM is present.
JBoss AS 4.2 also functions as a Java EE 1.4 application server, but deploys Enterprise JavaBeans 3.0 by default. It requires the Java Development Kit version 5. Tomcat 5.5 comes bundled with it.
JBoss AS 5.1, released as of 2009, operates as a Java EE 5 application server. It is a minor update of the major release JBoss AS 5.0, which had been in development for 3+ years and is built on top of a new JBoss microcontainer.
JBoss AS 5.1 contains a preview of some elements from the Java EE 6 specification.
JBoss AS 6.0, the current stable release and an unofficial implementation of Java EE 6, was released on December 28, 2010. Although JBoss AS 6 does support the full Java EE 6 stack.
Alpha quality releases of the next version of JBoss AS, JBoss AS 7, are listed on the JBoss AS community download page.
