Glink for Windows 32bit

>500.000

Versions

DOS new functionality suspended at 6.0 level error correction on an as-needed basis

Windows 16/32 dual version new functionality suspended at 6.2 level error correction on an as-needed basis

Windows 32 only version new functionality goes into 'Professional

Edition'

Glink Professional futureWindows 32 bit version has a future…….

……with Microsoft….Windows 98Windows NTWindows 2000

Glink script support

point to a startup script

From file menuExecute script fileExecute script

to keyboard macros

Uses a graphical user interface

Configurations are stored centrally

Glink administration

Glink as an applet

Java applications can be written as applets, and delivered on demand

Applets are delivered from a web server to the browser, and execute inside the JVM of the browser

The Glink applet collectsthe configuration detailsfrom the server

Launched from an HTML page

The browser downloads the applet

Glink connects...

..you are in direct communicationwith your host application

Glink application versionGlink and the administration program

included as Java applications that can be installed on the desktop

They escape the limitations of the browser

Applications are faster no browser overhead no browser memory limits choice of JVM

No more memory for you mister

And no, you can’tbring your own VM!!

Delivery, any Web serverGlink is downloaded by your browser from your web site as an automatically installable desktop Java application...

….and runs as an independent application on your desktop

At your convenience Glink is downloaded from the web server and automatically installed on the workstation

What about an API?

You want the host data….

What about e-business?The need for legacy application access

moves from the workstation to the application server

The good news isthat both APIsrun on the server

Take the Glink for Windows

API, make a COM+ object

Already delivered pre-beta

Ready for beta end June

Going another way Multiple platforms, multiple OS

Take the Java API

Produce Enterprise Java Beans

In terms of J2EE standards

Glink for Java API becomes a tool for developingconnectors

Connectors encapsulate heterogeneous Enterprise Information System access in a standardized way

Bull and G&R will in cooperationdevelop a connector for GCOS

EJB generation (4Q00) Using a tool that drives Glink for Java via the API,step manually through the application

The tool records the calls to the API that are used…..

Compile the recorded Java code as an Enterprise Java bean

…and remembers the input fields that are needed, and the output fields marked as the desired result

The bean duplicates the host access sequence, using parameters for the input fields, and delivers the output fields as the result
