JOnAS Java™ Open Application Server

Originally developed by Bull and Evidian, JOnAS is an Open Source implementation of the J2EE™ specifications. JOnAS is a pure Java™ implementation of this specification that relies on the JDK. JOnAS is part of the ObjectWeb Open Source initiative, which was launched in collaboration with several partners, including the France Telecom R&D division and INRIA.

JOnAS is now hosted on the ObjectWeb site.

JOnAS has already been downloaded by more than 50 000 people and is used in hundreds of operational applications, including e-commerce, e-portal, management systems, intranet applications, document processing, inventory systems, reservation systems, and banking applications, with different operating systems (Windows, Linux, Solaris, AIX, HP-UX, …), different JVMs, and different databases (Oracle, PostgreSQL, MySQL, SQL Server, Access, DB2, ObjectStore, Informix, Interbase,…).
