Shows how to apply Crupi s Core J2EE Patterns to your organizations legacy systems that were not written in Java.

Includes guidelines on how to reduce time and cost for application development by increasing re-use and quality.

Provides a powerful method to encapsulating legacy systems with J2EE patterns. This book presents a powerful method that makes J2EE applications portable across any underlying Enterprise Information Systems so they are more resilient to change. It addresses the question of how to properly encapsulate legacy systems and make them usable on the Internet. The authors discuss methods and techniques to standardize the encapsulation process make the process more efficient, by producing an integration tier that effectively shields the J2EE part of an application from the properties and demands of its legacy part. Encapsulating a legacy system is a huge task It requires a thorough understanding of the "new" object-oriented J2EE world and the old Cobol/mainframe world. By developing a standard, the process of legacy system encapsulation can be performed outside the scope of regular application development projects, at a sound pace, and provide a solid foundation for subsequent application development projects. The authors provide guidelines on how to reduce time and cost for application development by increasing re-use and quality and how to increase the migration potential for applications to provide a method to keep up with changes in the Enterprise Information System. This book shows how to apply Crupi s Core J2EE Patterns to your organizations legacy systems that were not written in Java.
