Agenda





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

• HATS provides cascading style sheets such as blacktheme.css (referenced in the classic terminal template) to assist in duplicating the green screen in HTML

• 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).


Achieving a Modern Web Look with HATS

• Customize screens with intuitive web user controls, including: Popup lists, drop-downs, checkboxes, lists,

radio buttons, calendar popups, graphs, etc.

• Simplify screens and work flow by Split one screen into multiple screens Organize data in tabs Remove functions / actions no longer needed

by removing full screens or partial screens

• One customized Web page can be applied to more than 1 host screen!


HATS Customized Transformation


Improve Navigation & Productivity• Macros & Global Variables

Skip unnecessary screens Combine screens Enter data on behalf of the end user Store end user input as global variables to use

again Prefill 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

• Native keyboard support

Application to Application Integration

• Create Web Services from programmed interaction of one or more host applications. Generate Java Beans

and EJBs from macros that navigate host applications.

Use IBM Rational Software Development Platform to add WSDL components.

• Supports session pooling. Create cached, logged-

on, ready to use host connections.

• Generate Struts and JavaServer Faces (JSF) Web applications.

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.


Concepts

1. A macro is a script that drives navigation through a set of host screens.

2. An Integration Object (or IO) is a Java bean that runs a macro.

3. Web Services, JSF / Struts Web applications, and EJB Access Beans can all drive Integration Objects.

WebService

JSF / StrutsWeb App

EJB AccessBean


Visual Macro Editor (VME)

• The VME is tool for visually developing HATS macros.

– Macros are the scripts that navigate and interact with 3270, 5250, VT host applications.

– Macros are the foundation for the Web Service support provided by HATS.

– Inputs and outputs in a HATS macro are eventually manifested as inputs and outputs in a Web Service (screen interactions are hidden behind the Web Service interface).

• The VME provides value by:

– Significantly increasing the productivity of HATS macro developers.

– Allowing for easier handling of alternate / error flows.

– Helping decrease the number of logic / flow problems (since the flow can be clearly analyzed by both developers, expert users, and business analysts).

Why Visualization is ImportantCurrent HATS macro tooling:

Here is the same macro

It is much easier to understand the logic of a macro and find logic

errors and missing flows when you can see the entire macro!

Can you easily determine the flow

of this macro?

Many possibilities!

• iPhone and iPod touch Pervasive Economical Easy to use

• New Redbook draft: System z on the Go! Access to z/OS from Smartphones

Customized System z Application

IBM i application with compact table support


Table and Subfile Mobile Optimization

• This enhancement enables tables to be collapsed and expanded so that more data can fit in the table or subfile representation without resulting in horizontal scrolling.

• As an additional option, the table and subfile widgets will create the expandable areas for retrieval by the browser only when requested

– Uses AJAX technology

– Reduces the memory and size footprint on the client device

• The feature can also be used in standard HATS Web applications.


Simplified, Customizable Web service Signature• Default inputs and outputs:

Prompts Extracts Chaining properties when necessary

• Customizable input and output names

• Benefits: Easier to understand No extraneous parameters means

less overhead

Defaults to defined inputs and outputs Customizable names


AJAX-based Automatic Refresh and Disconnect• Pain points with connectionless HTTP protocol: Host applications that do unsolicited screen

updates Host applications that unlock the keyboard

after end user submits Browser close or network disruptions

• Existing solution- server push Applet that established TCP connection to

HATS runtime and updated page based on host screen updates

Difficulties: TCP connection causes firewall and configuration

issues

Java in the browser

• New option- AJAX-based client pull Configurable client poll via AJAX/HTTP for

screen updates and disconnect detection Benefits:

No Java in the browser No firewall issues


When HATS application is active in the client browser window:

1. The host application sends an asynchronous screen update to the HATS web application.

2. The HATS client-side processing “polls” the HATS application using an AJAX-based request.

3. The HATS application responds with an indication that the host screen has been updated.

4. The client-side processing sends a “refresh” command to the HATS application to update the view in the browser.

5. The browser receives the updated HATS web page.

HATS Client-side processing in the browser polls the server-side application at a regular, defined interval to check if a host screen update has occurred.

If you close the browser, browse away from the HATS web application or lose network connectivity to the application server:

1. The polling request is not sent or cannot be delivered to the HATS application.

2. The HATS application checks to see if a polling request has been received within the defined disconnect delay interval.

3. Since no polling request has been received, the HATS application initiates disconnect event processing which includes terminating the connection to the backend host system.

HATS Web Application receives “polls” from the client-side processing at regularly, defined intervals. If the poll requests are not received within a configurable interval, the HATS web application performs disconnect event processing.

Inline Calendar Widget

No pop-up blocker issues Better look- inherits style from project templates


JSR168 Portlet Single Sign-On

• Add Web Express Logon (WEL) support for JSR168 Portlets

WEL is a macro based implementation of single sign-on

Allows users to access multiple host systems and host applications without providing additional credentials (user ID + password) for host systems

• Benefits: No need to administer and

maintain multiple host logon identities

Reduces password related support calls


Extract Non Text Planes in Macros

• Many host applications use color or other attributes relay information

• Now macros that extract to global variables can easily extract non text plane data

• Notes: Use of non text planes requires Java

programming skills to use the data returned.

Non text data can only be extracted into global variables.

Non-text data extractions work for macros resulting from a Play action, a Perform Macro Transaction action, and for extract global variable actions. This feature will not work for IOs or Web Services (there are other documented ways of extracting non-text data in IOs)
