Download the trial

IBM® Rational® Host Access Transformation Services (HATS) transforms traditional text-based interfaces—such as 3270 and 5250 green-screen applications—into web, portlet, rich client or mobile device user interfaces. It also extends 3270, 5250 and virtual terminal (VT) applications as standard web services. With Rational HATS, you can easily convert traditional text-based host application screens to user-friendly GUIs.

Rational HATS is available in the following packages: Rational HATS for Multiplatforms and HATS for Linux® on zSeries®, Rational HATS for 5250 Applications on Multiplatforms, and Rational HATS for 5250 Applications on i5/OS®.

Rational HATS allows you to reuse and repurpose your existing assets in innovative ways.

  • Terminal applications—transform the user interface of your 3270 and 5250 green-screen applications.
  • Web services—extends 3270, 5250 and VT application core business logic as web services or JavaBeans.
  • Customization—provides customizable workflow and application navigation.
  • Toolkit—provides wizard-based, visual development including visual page design and macro editing.
  • Deployments—route applications to IBM WebSphere® Application Server and IBM WebSphere Portal Server, as well as a number of devices and clients.

Terminal applications

  • Allows tunable default rendering of all non-customized screens of the application.
  • Transforms specific screens using screen customizations and transformations.
  • Transforms terminal application components, such as function keys and menu items, into intuitive links, buttons or text with images.

Web services

  • Captures screen flows, inputs and outputs with a wizard-based macro recorder. Lets you edit what is captured with the Visual Macro Editor, and creates integration objects and web services from the screen flows.
  • Reuses terminal application business logic in new business processes and applications.

Customization

  • Rational HATS simplifies screen navigation with macros and screen combinations.
  • It uses global variables to store data, pre-fill drop-down menus or pop-up windows, and input information for the user.
  • Rational HATS can transform a text-based user interface with a rich set of GUI widgets, such as drop-down menus, calendars, tables, pop-up windows and radio buttons.
  • Using business logic, Rational HATS augments terminal applications by aggregating terminal application data with other data sources.

Toolkit

  • The Rational HATS Toolkit works with a supported Rational integrated development environment (IDE), such as IBM Rational Application Developer for WebSphere Software.
  • It provides access to standard Eclipse features such as Java development tools.
  • The Toolkit features a wizard-based development process for creating Rational HATS applications.

Deployments

  • Create standard web applications for deployment to WebSphere Application Server.
  • Customize portlets with the Rational HATS Toolkit for deployment to WebSphere Portal Server.
  • Optimize your web applications for mobile devices running Apple iPhone OS or Microsoft® Windows® Mobile.
  • Create a standard Eclipse rich client application for deployment to IBM Lotus® Notes®, Lotus Expeditor or Eclipse Rich Client Platform.
