There is a strong shift in the industry toward reuse of the existing software and hardware resources within the companies to minimize the IT cost. Instead of creating or buying a new solutions, companies are trying to build a set of reusable software components based on the existing applications. These components can be quickly assembled in many different ways to satisfy the business needs of the companies. This environment is based on service-oriented architecture (SOA) and solutions that support business process automation. This book provides the detailed information about multiple ways for building SOA-based solutions around the System i platform. The discussion in the book covers the server and client side implementations that include: - ProgramCall in IBM Toolbox for Java - Host Access Transformation Services (HATS) - DB2 Web services - PHP - IBM Web Services Client for ILE - Java-Server Faces (JSF) Parts of the book are appropriate for CIOs, system architects, and application developers.

While the IBM WebFacing Tool is probably the most commonly known component of WDSc, there are many other tools combined into a single product. All those components together provide a complete workbench based on the Eclipse framework for the application developer for OS/400 or i5/OS. This IBM Redbook discusses WebSphere Development Studio Client for iSeries V5.1.2 and WebSphere Development Studio Client Advanced Edition for iSeries V5.1.2. The Development Studio Client includes several powerful tools that are targeted to iSeries application developers: WebSphere Studio Site Developer or WebSphere Studio Application Developer iSeries-specific features, such as: - Remote Systems Explorer - IBM WebFacing Tool - Web Interaction Wizard - CoOperative Development Environment (CODE) - VisualAge RPG - Integrated iSeries debugger

The IBM WebFacing Tool, part of IBM WebSphere Development Studio Client for iSeries, is one of the most important tools for IBM eServer iSeries developers. It facilitates quick conversion of existing host applications into Web applications. WebSphere Development Studio Client for iSeries comes in two editions, Standard and Advanced, each of which support a different level of features. WebSphere Development Studio Client for iSeries Advanced Edition V 5.1.2 introduces support for system screens for the WebFacing applications. This new feature removes one of the biggest limitations of previous versions of the IBM WebFacing Tool. This IBM Redbook provides helpful guidance to developers who are new to refacing applications using the IBM WebFacing Tool. It also offers advanced techniques to developers who have some experience in using the IBM WebFacing Tool and want to refine their Web applications. First, this book introduces you to the IBM WebFacing Tool. Then it walks you through a scenario, which involves converting a 5250 application to a Web application. Next it explains how to refine your browser interface and customize a WebFacing application. Finally, it discusses how to integrate and extend your WebFacing application to provide the required and added functions.

Gain a solid understanding and practical skills for the new development tool, the IBM WebFacing Tool. This IBM Redbook offers you a complete guide to help you on your way. You can use the IBM WebFacing Tool to build a Web interface to existing host applications on your IBM eServer iSeries server. All that's required for the tool to work is the availability of the data description specification (DDS) files for the host applications. The IBM WebFacing Tool offers the following advantages: - A quick and easy way to Web enable your host application - A fast learning curve so you don't need to acquire Web application development skills - The ability to continue using existing programming skills This redbook explains how the application conversion works and how you can customize your Web interface. It explains how to work with JavaServer Pages and cascading style sheets. It also offers helpful performance considerations and troubleshooting tips. Plus it looks at how to deploy WebFaced applications to Apache Tomcat. This redbook is written for iSeries application developers who want an easy way to extend the life of existing host applications. It also applies to those who want to expand the reach of existing host applications to a wider set of clients.

Whether you want to write your own Web applications or move existing applications to the Web, IBM lets you do this with a number of host access products. The newest addition is the IBM WebFacing Tool – part of the new WebSphere Development Studio Client for iSeries (Development Studio Client). The WebFacing Tool converts existing Data Description Specifications (DDS) into Java artifacts that are deployed in an application server. With the WebFacing Tool, existing iSeries applications require minor or no modifications and are accessible from the Web and iSeries display devices. This IBM Redbook discusses WebSphere Development Studio Client for iSeries, the WebFacing Tool, and several more powerful tools, which include: - WebSphere Studio Site Developer Advanced: The new integrated development environment (IDE) for developing applications. It offers the unique ability to add new features in the form of plug-ins. - Cooperative Development Environment (CODE): Workstation- based tool that supports the development of applications in many different host languages, including RPG and Java. - VisualAge RPG: Allows you to create and maintain client/server applications on the workstation. - IBM Distributed Debugger: Lets you detect and diagnose errors in code developed with OS/400 Integrated Language Environment (ILE) and Original Program Model (OPM) languages and Java.
