Regarding the shortcomings found with the traditional method of integrating a J2EE (Java 2 platform enterprise edition) Web Container, a two-layered Web container integration framework is proposed: the outer layer is independent of the Web container implementation and is the interface between the Web container and management tools, deployment tools and other modules; the inner layer is an extension to the Web container. The framework has been implemented on the J2EE application server PKUAS (Peking University Application Server). Test results have shown that this framework can satisfy the design goals of a pluggable, unified configurable Web container, and its performance is satisfactory.
