Building a service provisioning system using the Enterprise JavaBean framework

This paper provides an overview of the Sun Microsystems Enterprise JavaBeans/sup TM/ application framework in the context of a service provisioning system for GTE's IP Telecom offerings. The provisioning system takes advantage of the capabilities of EJB to provide a scalable, robust system that supports easy introduction of new services. The paper further describes the strengths and weaknesses of EJB as discovered while implementing this provisioning system and presents the authors' approaches to the EJB shortcomings. It concludes with a discussion of the future directions of EJB and how the identified limitations are being addressed in future revisions.
