Hello World: WebSphere Host Access Transformation Services

Transform a green-screen application to run in an Eclipse environment

Taravia Maynard, Software Engineer, IBM

Taravia Maynard is a Software Engineer at IBM in Research Triangle Park, North Carolina. She works on the Host Access Transformation Services test team.

Summary: Learn the basics of IBM WebSphere® Host Access Transformation Services (HATS). This tutorial includes demos and two practical exercises that teach you how to develop, transform, and test a rich client application. The client application is then deployed in a production Eclipse Rich Client Platform (RCP) environment.

Before you start

About this series

The Hello World series is for novice developers who want a high-level, hands-on overview of IBM software products. Each tutorial in the series provides simple exercises and step-by-step instructions to familiarize you with the components and use of a particular product. Upon completing a tutorial in the Hello World series, you will know enough about the product to begin exploring and using it on your own.

About this tutorial

This tutorial provides an overview of IBM WebSphere Host Access Transformation Services (HATS). Specifically, it demonstrates how to easily transform access to portions of a green-screen application using rich client GUI applications that run in an Eclipse Rich Client Platform (RCP) environment. The application developed in this tutorial is targeted at internal users accustomed to using a traditional fat-client terminal emulator. These exercises step through the creation and deployment of a HATS rich client project to an Eclipse (RCP) environment and the creation of a signon macro, screen customization, transformation, and screen combination for a zSeries® application.

Objectives

In this tutorial:

Create a HATS rich client project, a signon macro, a screen customization, transformation, and a screen combination for a zSeries application
Learn to use HATS to build native client applications.

Prerequisites

You should be familiar with one of the IBM Software Delivery Platform products that HATS supports, and have some knowledge of zSeries applications and Eclipse RCP.

System requirements

To complete the steps in this tutorial, you'll need a system with Microsoft® Windows® and WebSphere Host Access Transformation Services Toolkit V7.0 installed on an Eclipse-based, IBM Rational® Software Delivery Platform product. IBM Rational Application Developer is used in this tutorial. Download a free trial version of WebSphere Host Access Transformation Services Toolkit V7.0.

Internet connectivity is also needed to interact with the sample terminal application used in this tutorial.

HATS rich client applications can be deployed directly to Eclipse RCP or Lotus Expeditor Client. Therefore, an Eclipse RCP or Lotus Expeditor Client that HATS 7.0 supports must be installed on your system (see Resources links to this and other material).

For more information on HATS prerequisites and supported HATS Toolkit and runtime environments, see WebSphere HATS Detailed System Requirements (see Resources for a link).
