Internet bornOctober 20th 1969

First packets sent by Charley Kline at UCLA as he tried logging into SRI.

The first attempt resulted in the system crashing as the letter G of LOGIN was entered.

The Web came along

But then…..

GCOS over TCP/IPMuch more than Telnet

Glink sessions via Ggate

Host Links sessions (GUFT, Gspool, CPIC applications)

Local server with Ggate and Host Links

MainWay or FCP7/8 with RFC1006

e-Business architectures“GCOS on the web”HTML converters (screen scrapers)

These convert the existing host screens to HTML on-the-fly for display on a browser.

Face-lifting HTML converters These allow you to enhance the HTML by

extending it, or replacing it.

Application Programming Interfaces These products make the existing screens

‘visible’ to a programming language, such that the programmer can use the host applications as background resources in new e-business applications written specifically for the browser users.

Gweb scalability

Gweb runs on platforms from Windows 2000 to the largest UNIX systems, from Linux to AIX

G&R will port Gweb, and the Host Links products to new Bull servers based on the Intel® Itanium™ processor family!

Three tier architectures

Application Programming Interfaces e-business logic needs access to hosts

The simplest Web APIYou remember GlAPI? and Perl?

We married them and got…

Any Web programmer knows Perl. It is free of charge, and supported on all platforms. It has an extensive library of free routines for almost all purposes, including HTML generation.

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
