Jonas Certification
JOnAS is Java EE 5 certified, as of March 17, 2009. It was the first open-source server certified for free, using a process known as "J2EE scholarship" and established by Sun for non-profit organizations[citation needed]. JOnAS is generally considered to be technologically superior[citation needed]. The new JOnAS 5 architecture is based on top of an OSGi framework which makes the development of dynamic component much easier than before[citation needed].
Management console
JOnAS has a comparatively clear remote management console, providing easily accessible tools for remote uploading and deploying of the web applications[citation needed], configuring both secure and ordinary web access ports and managing the user name - password - role datasets. This console is based on the JavaScript[citation needed]. From the first impression, the consoles of the comparable open source J2EE servers seem more confusing, with many needed features not immediately visible[citation needed]. This is, however, more important in the teaching process, as J2EE servers are not meant to be managed by the unprepared end user[citation needed].
Environment
JOnAS is an open source Java EE 5 application server. It provides a fully compliant EJB container through EasyBeans and is available with an embedded Tomcat or Jetty web container. Any 1.5 or 1.6 JVM is supported, and the attempts to run on a free stack with GNU Classpath are very promising. JOnAS can run on numerous operating systems including Linux, Windows, AIX, many Posix platforms, and others, as long as a suitable JVM is available.
