\ BooknewsThis guide to the various technologies available for web-enabling a legacy application also shows how to design a redeployment strategy and implement the revitalization architecture. The author outlines the green-screen interface, details the Java server/client middleware that emulates an AS/400 display file, and shows how to build a Swing user interface and a browser user interface. He then walks through the process of using FTP to transfer software to the AS/400, installing the Java Development Kit, and configuring IBM's WebSphere application server. The CD-ROM contains workstation, host, and middleware software required to use the revitalization architecture. Annotation c. Book News, Inc., Portland, OR (booknews.com)\ \
