Description:This title seeks to teach readers how to build secure, real-world applications using EJB and CORBA components as the building blocks. It includes an overview of n-tier security requirements. It then explains how components can be used to provide security at all system levels and how to provide integrated solutions across all domains. It shows how to integrate the different security models for EJB and CORBA, combining the best of both technologies and illustrates all of the concepts presented by building a sample e-commerce system using Java with EJB and CORBA. It also presents case studies of implementations in finance, manufacturing, and telecom.
