Abstract :
Leaf, the Lean and Extensible Architectural Framework is an enhancement wrapper for J2EE implementations. Basically, LEAF fixes some identified J2EE issues and extends, as well as simplifies. the use of the J2EE by providing several incremental improvements. These improvements are seamlessly integrated, include an additional component type, allow the same interfaces for local and remote service implementations offer better J2EE implementation compatibility and ORB interceptors, and encompass several new technical services. This paper explains the need for LEAF through a diagnosis of the J2EE, presents the fundamental concepts underlying LEAF, overviews its implementation, reports on field experiences from using it in a number of commercial projects, and points out some interesting tradeoffs in using the J2EE with and without LEAF.
