  • On this chart just stress how important existing applications are to customers Customers have made a significant investment over the years to develop fully functional applications, finely-tuned deployed in a reliable, robust and scalable infrastructure. However their applications can only be accessed by a terminal, and are difficult to navigate. It’s hard to train the new generation of employees to use these old-style applications, therefore customers are faced with high training costs. Why throwing away these applications ? It’s much less expensive to reuse existing applications than to write new applications from scratch. Reusing robust applications also reduces the risk and allows for faster time to market.
  • IBM WebSphere Host Access Transformation Server gives you all the tools you need to quickly and easily extend your legacy applications to bus. partners, customers, or employees. HATS makes your 3270 and 5250 applications available through most popular web browsers, while at the same time converting them to graphical user interfaces (GUIs) with a web-like look and feel on the fly in real time HATS provides a zero footprint Web-to-host solution, so that the only software your users will need is a web browser HATS can add drop down lists, tables, radio buttons, tabbed folders, and much more to your host screens. The power of HATS is in its ability to accurately recognize host screens and transform them in real time to an HTML interface according to a set of predetermined rules
  • IBM WebSphere Host Access Transformation Server gives you all the tools you need to quickly and easily extend your legacy applications to bus. partners, customers, or employees. HATS makes your 3270 and 5250 applications available through most popular web browsers, while at the same time converting them to graphical user interfaces (GUIs) with a web-like look and feel on the fly in real time HATS provides a zero footprint Web-to-host solution, so that the only software your users will need is a web browser HATS can add drop down lists, tables, radio buttons, tabbed folders, and much more to your host screens. The power of HATS is in its ability to accurately recognize host screens and transform them in real time to an HTML interface according to a set of predetermined rules
  • Let’s talk about how HATS can help customers meet these requirements HATS is a rules-based Web-to-host Transformation engine that can dynamically create a new easy-to-use GUI interface for your green-screens apps. It allows to significantly improve the navigation and productivity of host applications and integrate them with other apps within a portal or a rich client environment. it allows to extend terminal apps tasks as web services. It requires low skills, it’s highly customizable, and does not require any changes to your existing apps. Also HATS supports iterative development – introducing next chart.
  • This slide illustrates HATS deployment options WEB - HATS apps can be deployed as WEB apps that can be accessed via a traditional browser with zero footprint at the client. Portal – can be integrated with other application within a portlet. Web Services – can be exposed as Web Services Rich Client – can be integrated at the desktop with other Eclipse bases applications within a Rich Client - allowing to take advantage of a rich set of user interfaces widgets Mobile – and also can be accessed via PDA, Cell phones etc.
  • HATS has the capability to achieve a traditional green screen look. Please turn to slide 20.
  • Here’s an example of a modern Web look with HATS. Note that the host components, selection lists, function keys, are displayed as widgets selected by developer.
  • This screen shows the capability to define a rule based on the title of a field. For example, every time a field contains the word date, the global rule ties a calendar input widget to the input field, so the end user can just click on the icon beside the field and use the widget to populate the date field. Keyboard entry of a date is still possible, giving all users a chance to use their preferred entry method. The valid value pull down list provides users with words to choose from instead of typing in a difficult variable normally required when using a traditional green screen. This eliminates user error and the need to memorize a long list of complicated variables.
  • A JSR168 cooperative portlet is shown on this page.
  • One of the most exciting features in HATS version 7.1 is the ability to extend transformed green screen applications to mobile users. This feature gives an increasingly mobile work force real time access to critical host application data right when they need it, vs having to wait until they can get to their laptop or office to check something or make an update. For example, a service engineer could mark a repair complete, or check inventory, and order a part if necessary. A warehouse employee could make updates to a terminal application using a handheld device. Prior to HATS 7.1, you could use HATS Integration Objects or Web services to give mobile end users access to terminal application data. Now, in HATS 7.1, end users can connect to a HATS transformation application from a mobile device using Internet Explorer Mobile browser version 5 or later. The HATS developer can customize the host application specifically for mobile users to make it easier to use, streamline the navigation flow, and use business logic to integrate the terminal application with other data sources, such as a database.
  • This slide shows data from multiple sources 5250 (main transformation), 3270 (perform macro transaction, extract to GV), and VT (perform macro transaction, extract to GV).
  • Before exploring the improved SOA tooling available in HATS 7.1, let’s step back and review why HATS is an important part of IBM’s SOA story. SOA is all about helping customers create new value by helping them identify application assets that are mission critical and then reusing those assets in new ways. HATS enables customers to reuse logic locked within their green screen application without requiring access to or understanding of application source. No costly, risky rewrite or reengineering is required. In addition, HATS is the only IBM product that can be used extend a wide variety of terminal applications logic as standard Web services. HATS handles 3270 applications, including CICS, IMS, TSO, and ISPF, 5250 applications, and VT terminal applications.
  • We used a mixture of RAD, RBD, RSA, Rdz, but the only functions we really used were those specific to HATS, Web Development (JSP, HTML, CSS), or Java Development. HATS includes licensing for WebSphere Application Server, but the version is different based on HATS licensing: HATS for 3270 gets WAS ND HATS for 5250 on mulitplatform gets WAS Base HATS for 5250 on System I gets WAS Express

  • So- in summary, HATS 7.1 provides a large variety of deployment options to meet the business needs of your customers. HATS rich client applications can be deployed to Eclipse RCP and Lotus Expeditor, and they enable integration with other desktop applications, client side processing, and a rich user interface. HATS Web applications extend terminal application access to a wide variety of browsers, providing a zero footprint client. HATS portal applications allow integration of terminal applications at the glass, and now the strategic JSR 168 portal API is supported. HATS mobile support allows anywhere/anytime access to mission critical terminal applications, and finally, HATS Web service support enables customers to create standard Web services from green screen terminal application tasks, so that the application logic can be used in new ways. Common across all deployment options is a quick return on investment- host applications can be quickly accessed through a new, intuitive user interface. In addition, HATS is a low cost, low risk solution. There is no need to rewrite applications, and HATS is based on open, proven platforms and technologies such as J2EE, Eclipse, and Web services. And finally, HATS can be used to increase productivity of your end users, and decrease the training costs by making those green screen applications easier to use and providing streamlined navigation.

  • Two main points: How HATS works: The path of a screen sent from the host to HATS displaying end user presentation. HATS action list offer a flexible and easy way to customize your application beyond the user interface. Using HATS Toolkit, the Developer has customized particular screens. At runtime, whenever HATS receives a host screen, HATS checks through its customized screen list for a match of the screen recognition defined by the Developer. If there is no match, the screen is not customized and so will be displayed using Default Transformation. If the screen is customized, HATS will run its action list. The HATS action list is a powerful way to modify the application logic as well as customize the user interface. The content and order of actions in the list were created by the Developer using HATS Toolkit. A simple case of an action list to is to run a customized transformation of the screen, thereby simply modifying the content the end user sees. A more extensive example is one where multiple actions are performed, in order, until the action list is complete. In this example, the Developer will get a global variable value set perhaps by collecting some data the end user has entered on previous screens. Let’s use a scenario where a customer calls in to a bank’s customer service rep and to set up a credit account. The global variable could be set to the customer’s bank account number. Using the account number, the business logic runs to determine if the customer is in good standing with his other accounts. The business logic may return a customer rating. The customer rating may be sent to the HATS macro, where the macro navigates through numerous host screens to get to a screen to present to the customer service rep. The screen may indicate the credit limit the customer may be given based on his account rating, along other information. When a macro runs using HATS, the keystrokes recorded in the macro for a particular screen are sent to the host, the host sends a screen to the macro, and the process proceeds until the macro is complete. In our example, the macro would end on the Credit Limit screen, which would then be sent through the Screen Customization logic before being presented to the user. Question : What happens if I change my green screen application? Answer : If using default rendering, HATS picks up the change automatically and transforms the screen. In other scenarios, depending on the type of change and how the application was customized, further modifications may need to be made to the HATS application. If you have made your screen customization logic general enough so that the host screen change is still within the location/specification of the screen recognition, your HATS application will not need to change.
