Overview

IBM WebSphere® Host Access Transformation Server (HATS) gives you all the tools you need to quickly and easily extend your legacy applications to your Business Partners, customers, and employees. HATS makes your 3270 and 5250 applications available through the most popular Web browsers, while at the same time converting your host screens to a Web-like look and feel.

HATS' rules-based engine can make it possible to extend your host application to the Web within a single day of installing the software, without having to make any changes to your host application. HATS is a zero footprint Web-to-host solution — the only software needed on the client is a Web browser.

The power of HATS lies in its ability to accurately recognize host screens and transform them in real time to a Web interface according to a set of predetermined rules. A collection of default rules is included with the product. It is easy to modify these rules according to your specific needs and taste. HATS can add a variety of elements such as drop down lists, hot links, tables, buttons, and tabbed folders to your host screens. HATS can also add HTML elements such as logos, pictures, backgrounds, and Web links. HATS' macro support allows you to provide programmed navigation through multiple legacy screens. For example, you can take your end users directly to the first screen they need to see, bypassing all screens in between. HATS can also use macros created in IBM WebSphere Host On-Demand or Host Publisher.

The HATS Studio is fully integrated within the Eclipse-based IBM WebSphere Studio. It offers an intuitive interface and easy-to-use wizards for customizing the rules for transformation of legacy screens. WebSphere Studio's application development features provide a variety of benefits, such as team development facilities that enable code management and synchronization across multiple developers.

Because it is built on WebSphere's industry-leading J2EE architecture, HATS has virtually unlimited flexibility and extensibility. Using custom Java™ development, you can extend HATS to integrate with other legacy systems or J2EE applications.

HATS is the newest member of IBM's market-leading Host Integration family of host access and Web-to-host solutions. HATS complements the IBM WebSphere Host On-Demand and Host Publisher products and is available exclusively within IBM's WebSphere Host Integration Solution offering.

Description

WebSphere Host Access Transformation Server

HATS' rules-based implementation can make it possible to extend virtually any 3270 or 5250 legacy application to the Web within a single day of installing the software. HATS' rules define how the various elements found on a legacy screen are to be transformed and represented using HTML. For example, the rules define whether menu selection lists should be represented unchanged as a legacy menu selection list, be represented as a pull-down option list, or be represented as a list of Web links the user would click on to make a selection. The HATS' rules are created once and are then applied to legacy application screens as they are encountered to dynamically generate the corresponding HTML Web pages for the end user. HATS' rules eliminate the need to customize individual legacy screens and help to significantly improve the time to market for new Web-to-host projects. The flexibility to customize unique individual screens within a HATS' flow is provided to preserve maximum deployment flexibility.

HATS provides the flexibility to have a single rule set used for all of your legacy applications, or alternatively you may choose to have different rule sets for select applications or select end-user communities.

HATS delivers a broad range of security options. On the Web side of a HATS implementation, all of the existing industry-standard Web security mechanism for securing access and authentication are enabled, including Secure Sockets Layer (SSL) for data encryption and client authentication. To existing applications, HATS will appear as a standard user of the application, which enables you to leverage your existing legacy security systems, such as RACF® on IBM eServer zSeries™, to control access to these critical resources.

HATS lets you add graphical HTML elements, such as logos, pictures, and backgrounds, to your host screens. You can add clickable Web links down the side of your screen, across the bottom, or anywhere else you like. HATS allows you to give your host applications the same look and feel as your Web applications, rather than being constrained by the presentation of your legacy system.

Local print support is an important capability when extending legacy applications to new users. HATS delivers an innovative means of providing this support by converting legacy print output into industry-standard PDF format. The resultant PDF file is then sent to the end user's browser, where it can be viewed locally, or saved to disk.

HATS provides strong host keyboard functionality. Although running in a browser environment, HATS is able to provide direct keyboard support for keyboard functions employed by the host application, such as PF keys, enter keys, clear keys, and system-request keys.

Portals are becoming increasingly popular as a way to provide maximum flexibility with a minimum of screen space. WebSphere Portal solutions can provide a personalized, single point of access to enterprise information. The HATS' portlet makes it possible for legacy applications to be included in enterprise portals, enabling you to consolidate all your mission-critical applications at one single point of access.

HATS Studio is fully integrated within the Eclipse-based IBM WebSphere Studio. The Eclipse platform is an industry-standard application development environment, providing the benefits of a common framework and unreusable skill set for development of Web-based applications. Integration within WebSphere Studio delivers a common tooling family for your e-business needs. WebSphere Studio application development features provide a variety of benefits, such as team development facilities that enable code management and synchronization across multiple developers.

The ease of use delivered by HATS can significantly minimize the skill level needed for typical Web-to-host deployment projects. Programming skills are not necessary to deploy and customize your host applications. If Java skills are available, HATS provides the tools to meet the needs of most complex and demanding enterprise e-business projects.

HATS' runtime components are generated by the HATS Studio and deployed to IBM WebSphere Application Server, which provides support for the workload management features required for enterprise class scalability and availability. Load balancing and fail-over support functions, such as vertical and horizontal cloning, are handled by the WebSphere Workload Manager. Vertical cloning allows requests to be distributed across multiple Java virtual machines, (JVMs), providing fault tolerance. If one JVM fails, a user request can be processed by one of the remaining clones.

Host Access Transformations Server Maximizes End-User Productivity

HATS delivers a wide range of end-user productivity features that:

  • Provide local print support by converting legacy print output into industry-standard PDF format. The resultant PDF file is sent to the end user's browser where it can be viewed, printed locally, or saved to disk.
  • Enable a WebSphere Portal. The HATS portlet allows legacy applications to be included within enterprise portal implementations.
  • Enable use of the end-user keyboard for typical control keys, such as function keys and enter keys.
  • Support the use of Host Access Class Library macros within a HATS implementation. A typical use of macros would be to provide programmed navigation through multiple legacy screens on behalf of the end user to improve user productivity.
  • Can include HTML widgets within HATS screens to add functionality or help improve end-user productivity. Examples of widgets would include: calendar widgets, calculator widgets, or widgets that provide an image related to the legacy screen, for example, a picture of a product for an order-entry screen.
  • Can integrate WebSphere Host Publisher Integration Objects within a HATS implementation to programmatically access legacy systems on behalf of the end user. This might be done to programmatically supply needed input fields for the end user with data pulled from related legacy systems.

Product Positioning

HATS is the newest member of IBM's market-leading Host Integration family of host access and Web-to-host solutions. HATS complements IBM WebSphere Host On-Demand and Host Publisher products and is available exclusively within the IBM WebSphere Host Integration Solution offering.

Within the Host Integration Solution:

  • Host On-Demand delivers the Java emulator solution providing desktop emulation on demand. Traditional emulator functionality is delivered via Java applets that are downloaded as needed and optionally cached on the end-user desktop. Host On-Demand is served as needed from a central Web server which can eliminate the time and expense associated with installing and maintaining software on end users' desktops.
  • Host Publisher delivers controlled access to legacy applications by Web browser users or new Web applications. Host Publisher requires customization, but delivers programmed navigation of legacy applications that provides exacting control over what legacy content is available to the end user. Host Publisher also delivers composite application support enabling multiple, different legacy applications to be combined into a single application appearance to an end user or Web application.
  • Host Access Transformation Server delivers a near load-and-go solution for rejuvenating legacy application screens that can improve end-user ease-of-use and productivity. The existing end-user flow through legacy applications is preserved, but is rejuvenated with a more Web-like look and feel. Delivery of HTML to the desktop can provide a zero footprint client solution with the broadest possible user reach.

IBM WebSphere Host Integration Solution delivers a comprehensive solution for host access and integration. Whether the need is traditional desktop emulation, Web-to-host Java client solutions, WebSphere Server solutions, rejuvenated legacy screens delivered via HTML, controlled access via HTML for Internet deployments, componentization of legacy assets for use within new Web applications, or extension as new Web services, IBM Host Integration Solution delivers the solution. IBM Host Integration Solution is a complete answer to host access and integration and it's all available from one company and at a single price per user.
