Enterprise JavaBeans (EJB) provides special functionalities such as transaction, persistence, location transparency and security. These functionalities can be considered as aspects and EJB can be regarded as an aspect-oriented programming (AOP) environment. However, its architecture has no extensibility and flexibility to add or modify aspects, so it is not considered as a general AOP environment and hard to be applied to diverse domains. In this research, a new EJB server, named AES, is designed and implemented. An aspect exists independently of a container, and can be added and updated as needed. A container is changed into a generalized metaobject supporting more aspects in a flexible and extensible way. Also, an EJBObject is changed as a reference aspect supporting various network protocols. To prove flexibility and extensibility of AES, a testing application and user-defined aspects are developed. Finally, overhead for supporting AOP in EJB is measured.
