  18. WebFacing New Features (2) • Customize each as separate projects • HATS project • Use HATS macros to automate application execution, control application flow, combine data from multiple IBM i systems, etc. • Improve the usability and attractiveness of screens by using transformations and different rendering patterns • WebFacing Project • Customize pre-converted screen artifacts • Convert the display files for the screens that are to be rendered by WebFacing Seamless interoperability between WebFacing and HATS applications!

  19. Green Screen WebFacing Web/EGL Composite Web/EGL, HATS, WebFacing Applications Application Bridge HATS WebFacing New Features (3) • Application Bridge • Enables you to seamlessly interconnect new Web applications (written with EGL for example) with WebFacing or HATS • Allows you to quickly modernize using WebFacing/HATS at low cost • Can iteratively add new function taking advantage of the latest Web technologies • Use the Application Bridge feature to pass data between Web applications such as EGL and WebFacing applications • EGL or Web services allow you to access IBM i batch services or data from a Web application • The application bridge allows you to link your new Web application to an interactive IBM i application and share data

  20. WebFacing New Features (3) • Application Bridge Scenarios • From WebFacing, call another Web application with data; the Web application does the necessary processing and then returns control to WebFacing with the data updates. • Other Web application can also invoke a WebFacing application with data and get the data updates back from WebFacing after it does the processing. • When used with the HATS/WebFacing Interoperability feature, you can make HATS and Web applications interoperate through the application bridge or make WebFacing, HATS and Web applications all work together. Cost-effectively modernize existing applications to the Web, take advantage of the latest Web technologies to build your new applications, and have those existing and new applications seamlessly work together!

  21. WebFacing New Features (4) • Firefox Support • WebFacing Web, portlet, HATS interoperability applications can now run on Mozilla Firefox • Information about Firefox: • Estimated market share is 20%-30% worldwide • Available on Windows, Mac OS X, and Linux platforms • Provides a lot of useful add-ons, e.g., Firebug, Web Developer toolbar • Tips • For a project migrated to V7.5, do a reconversion so the project can run properly in Firefox • Write cross-browser code in your customizations • Want to test with an unsupported browser? • WebFacing issues a WF0095 error stating that WebFacing requires Internet Explorer 5.5 or greater, or Firefox V2.0 or greater • To avoid the above error, set the web.xml variable WFIgnoreBrowserTypeCheck to true WebFacing supports multiple browsers (Internet Explorer 5.5 and greater, and Firefox V2.0 and greater), covering 90% of the global browser market!

  22. WebFacing New Features (5) • Limited Capabilities Users Support • Limited capabilities users: user profile has the LIMIT CAPABILITIES (LMTCPB) parameter set to *YES or *PARTIAL • LMTCPB is used to prevent the user from running programs outside of the menus • Works on V6R1 and later WebFacing supports limited capabilities users on V6R1 and later!

  25. What’s Different About HATS Now? • IBM Rational Host Access Transformation Services is the strategic offering from IBM to transform 3270 and 5250 green screen applications. • The IBM WebFacing Tool development and deployment are now all part of HATS. • Reasons that had impacted HATS adoption in the past have been negated: • Operating System Interactive workload requirement • Higher cost Hardware requirement • High deployment costs on IBM i

  26. Host Access Transformation Services (HATS) • What can you do with HATS? • Quickly and easily create Web, portal or rich client applications that provide an easy-to-use GUI for your green-screen applications • Low skills requirement • Highly customizable • Iterative development process • Transformation “on the fly” • Extend terminal application tasks as Web services • Benefits • Extend host application to new users • Improve the navigation of your host application • Reuse your existing assets in a Service Oriented Architecture • Avoid rewriting applications (no impact to code)

  27. Improve Navigation & Productivity • Macros & Global Variables • Skip unnecessary screens; combine screens; split screens, enter data on behalf of the end user • Store end user input as global variables to use again; pre-fill text entry fields • Improve User Interface with Screen Customization • Add buttons, hot links, drop-down menus, valid value lists, etc. • Modify graphics, fonts, colors, and layout • Add business logic • Local print support • Native keyboard support • Security – HTTPs, SSL • Performance – HTTP Compression, Contention Resolution • Supports iterative development • Default Transformation rules - fully functional HATS application on the web quickly • Customize Default Transformation rules • Customize screens

  28. Achieving a Green Screen Look with HATS • HATS supports host colors and extended field attributes, including: • Numeric only, alphabetic only, signed numeric, reverse image, column separator, underline, and blink fields • Supports automatic field advance • Host keypad and OIA can be displayed (and positioned anywhere) • Native keyboard support (i.e. pressing F12 in the browser sends F12 to the host application).

  29. Global Rules and Valid Value Lists

  30. HATS Customized Transformation

  31. Combining Screens

  32. Combine and Integrate

  33. Extends host applications to the desktop. Applications run on: Eclipse RCP 3.2 or 3.3 IBM Lotus Expeditor Client 6.1.x Provide a modern GUI interface to mission critical green screen applications. Processing occurs on the desktop (WebSphere Application Server is not required) Provides the capability to integrate host access applications with other applications on the desktop. Alternative to traditional terminal emulator products. Targeted at internal users in a controlled environment. HATS Rich Client Overview

  34. What is HATS mobile device support? • HATS transformation applications can now be accessed by pervasive devices such as cellular phones, data collection terminals, and Personal Digital Assistants • This allows for the HATS developer to: • Customize and transform individual screens • Add business logic to screen interactions • Enhance the presentation, layout, and flow of the original host systems • Supported browser: Internet Explorer Mobile 5.0 or later • Reminder: HATS Integration Object or Web service data can also be used in conjunction with mobile devices

  35. The Value of HATS SOA • HATS is an important part of the IBM SOA strategy! • IBM SOA Foundation helps to extend the value of the applications and business processes that currently run your business, not replace them. • HATS does not require application reengineering or rewriting • Rewriting can consume significant amounts of time and resources. • Rewriting requires access to and understanding of application source code. • Rewriting inherently introduces new bugs that must be found and fixed. • Simply put - rewriting is not an option for some customers! • HATS is unique • HATS is the only IBM product that Web Service-enables 3270, including CICS and IMS, 5250, and VT terminal applications – great for customers with a mix of applications (one tool can be used to enable all of them). • HATS generates standard Web Service interfaces • HATS services can be integrated into an existing SOA.

  36. SOA with the HATS Visual Macro Editor Web services are generated from macros. Macros can drive navigation, enter data, and retrieve data from VT, 3270, and 5250 (and WebFacing Server) applications.

  37. Other HATS SOA Capabilities • Connection pooling • Automatically connects a specified number of connections at application startup. Connections can be reused (this decreases connect/disconnect activity on the system). • Connect / disconnect macros • Automatically signs on sessions at startup and signs them out when no longer needed. • User lists • Signs on sessions using a set of predefined credentials. • User list information can be encrypted. • Stateful or stateless interaction (even for Web services) • Enables clients to have stateful interactions (i.e. the host session stays active between interactions) with host applications using Web Services.

  38. Summary of HATS Features and Value Propositions • Host screens are converted to GUIs on the fly, in real time • Improved navigation of host application • Zero footprint on the desktop with Web deployment • Support deployment to Rich Client • Access host assets from mobile devices • Combine screens and data from multiple applications • Eliminates need to customize every screen • Generate Web services from host transactions • Exploits security & scalability of WebSphere Application Server and WebSphere Portal • Extensible through IBM Rational Software Delivery Platform • Supports iterative development
