What is JAC ?
JAC (Java Aspect Components) is:
- An Aspect-Oriented application server in Java.
- An Object-Oriented and Aspect-Oriented development environment.
- Easy to learn and use.
- Free and available under LGPL.
JAC enables
- To separate concerns when programming (distributed) applications. For instance, the authentication, persistence, GUI or distribution can be cleanly modularized and considered independently from what the application is doing.
- To configure and modify these technical services.
- To build complex applications at incredible speeds with low development skills.
- To inter-operate with existing applications using our RMI, Corba/IIOP, or SOAP/XML (coming soon) communication layers.
The JAC release includes
- An IDE that supports UML to model the programs and to generate and compile the Java code.
- Ready to use aspects of persistence, authentication, sessions, deployment, load-balancing, synchronisation, remote access, transactions, SWING and Web GUI.
- An administration interface allowing to debug the application and to dynamically modify the configuration of the aspects.
- The JAC application server that provides a light-weight and open container for JAC objects and aspect components that can be dynamically added to provide new technical characteristics to the containers.
- A tutorial, development guide, programming guide, and examples set.
JAC is not
- A new language with new grammar to express aspects. You might want to see the AspectJ project for this.
The following figure is a screenshot of the JAC administration interface. Some interesting features can be noticed:
- Upper-left part: a tree view to navigate into the components that are created by the application (here the photos sample has been launched).
- Lower-left part: the tabs allow the user to know several details about the aspects running within the current application.
- Menus allow the user to select the current application (if several are running), launch new ones, and administrate them.
- Right part: the user can look into the application's components states and invoke some methods. Although this interface is not final-user oriented, it can be very helpful for debugging.
JAC also allows the users to browse their objects through the WEB. Live demo of the photos sample (still unstable).
JAC is an open source research project under the LGPL license, developped and coordinated by the AOPSYS company (Renaud Pawlak, Laurent Martelli), the CEDRIC lab. (Pr. Gerard Florin, Renaud Pawlak), the LIP6 lab. (Lionel Seinturier), and the LIFL lab. (Pr. Laurence Duchien).
