JOnAS application server
JOnAS is an implementation by ObjectWeb of the J2EE specification. JOnAS is a pure Java implementation of this specification that relies on the JDK. JOnAS is a project of the ObjectWeb consortium, which was launched in collaboration with several partners including Bull, the France Telecom R&D division and INRIA.
Distributed under the terms of the GNU Lesser General Public License, JOnAS is free software. In February 2005, JOnAS became the first free software application server developed by a non profit organization to become certified compliant with J2EE.
