Overview

A proven Java-based approach to standardizing and streamlining legacy migrationThis book focuses on the key challenges developers face when using the Java 2 platform Enterprise Edition (J2EE) to encapsulate legacy applications for delivery in a multi-tier Internet environment. Leading Sun architects Torbjoern Dahlen and Thorbioern Fritzon show how to standardize encapsulation using an integration tier that shields the J2EE elements of an application from the properties and demands of its legacy elements. Using this approach, enterprises can promote reuse, accelerate legacy migration projects, and make the most of their COBOL/mainframe and Java expertise. Above all, they can take portability beyond hardware and operating systems, systematically migrating virtually any legacy system without extensive redesign or reprogramming.Presents a pragmatic approach to domain modeling for legacy application migrationPromotes reuse and portability through a standardized, fine-grained domain object modelShows how to streamline the transformation of domain models to working systemsIntroduces a proven, pattern-based J2EE application architecture for Internet-enabling legacy systemsIncludes superior algorithms for object queries, data cleansing and merging, and artificial XA supportAdvanced J2EE Platform Development presents detailed examples and sample code, including a start-to-finish case study that demonstrates integration between three different legacy systems.
