This course will utilize a combination of instructor-led discussions and interactive workshops to illustrate the use of patterns, best practices, design strategies and proven solutions for designing web applications that incorporate JSPs, Servlets, EJBs, JMS and JDBC components. This seminar will focus on the J2EE Patterns Catalog and design strategies that can be utilized to incorporate them. Each of the patterns for the Presentation, Business and Integration tiers will be extensively investigated with an in-depth discussion of the context, problem addressed, forces impacting each, solution provided and the related consequences.

Prerequisites

Each student should have a basic understanding of application development and have been exposed to an object-oriented programming language.

Class Format

Lecture and Lab

Audience

System architects, Java or OO developers, Project Managers and other professionals that will be designing or deploying web applications.
