AOP Alliance (Java/J2EE AOP standards)


Aspect-Oriented Programming (AOP) is a programming technique that will be able to enhance several existing middleware environments (such as J2EE), or development environements (e.g. JBuilder, Eclipse).

Several projects now provide AOP-related techniques such as generic proxies, interceptors, or bytecode translators.

All these projects have their onw goals and speficities. However, several common basic components are still usefull (and sometimes required) to build a full AO system. For instance, a component that is able to add metadata on the base components, an interception framework, a component that is able to perform code translation in order to advice the classes, a weaver component, a configuration component, and so on.

To us, it would be great to be able to reuse different components coming from different projects to build a full AO system, and for three main reasons.

For these reasons, we think that a standarization of the interfaces of the aspect-oriented components would be great and will bring great simplifications for the entire AOSD community, but also for all the communities that will to use AOP in a close future.
