PKUAS ("Peking University Application Server") is a J2EE application server developed by the research group of PKU-Bell Labs Software Technologies Joint Lab.
The project began in 2001. Up to 2005, PKUAS had implemented J2EE 1.4 and EJB 2.0 specifications. PKUAS group is now working on supporting J2EE 1.5 and EJB 3.0. As a research project, PKUAS provides a platform to experiment with innovative ideas on new generation of software in the Internet environment. Besides the standard services listed in the specifications, e.g. Communication, Naming, Transaction, Security, etc., PKAUS has several distinguished features, including the on-line evolution of components, a flexible and extensible interoperability framework, and a reflective management framework. In order to support commercial applications, PKUAS also provides some tools, including a deployment tool which supports the remote deployment of components through a Web interface, and IDE plugins for Eclipse and JBuilder users. PKUAS group is now working with ObjectWeb, a nonprofit international consortium focusing on providing open source middleware.
A long-term goal of PKUAS is to support the internetware paradigm.
