Java EE: Patterns

Course Overview

The J2EE Patterns course provides students with a thorough description of software design patterns that can be used with the Java 2 Platform, Enterprise Edition (J2EE platform) technology to effectively solve complex business problems. Studying design patterns, such as the patterns presented in this course, assists developers in learning tried and proven techniques for solving specific types of common design problems. The design patterns described in this course help developers design enterprise applications that are more flexible, maintainable, reliable, and efficient.

This course describes the J2EE patterns, which were created by the Professional Services organization and the J2EE Blueprints group of Sun Microsystems, Inc. These patterns are based on these groups' many years of experience with a wide range of enterprise applications. Development teams can leverage this industry experience and avoid many costly and time-consuming project roadblocks by understanding and implementing these patterns.

This course also describes many of the Gang of Four object-oriented design patterns that provide the basis for the J2EE patterns and also provide the basis for good object-oriented design. Understanding these patterns is critical to the effective use of the J2EE patterns and valuable in the design of any object-oriented system.

Skills Gained

Students learn how to create effective software designs for J2EE technology applications through a series of lectures and exercises.

• Select an appropriate Gang of Four or J2EE pattern to solve a specific problem.
• Apply a Gang of Four or J2EE pattern to an architecture and implementation.
• Design and implement more effective J2EE applications.
