G&R web site renewed

Internet Anniversary 30 years old

Internet born October 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. Hobbes' Internet Timeline Copyright (c) by Robert H Zakon.

Commercial Internet Took off !!!! Telnet FTP The Web came along But then…..

GCOS over TCP/IP Much 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 RFC1006 over TCP/IP (G&R predates GTEA) FDDI-Hub (LAN-Extender) Glink, Gweb, PC and Host Links applications UNIX or Windows NT PCs Glink FCP7 FCP8

The new world: e-business Intranet Extranet Internet Customers Enterprise E-Servers Suppliers Data centre

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 API You 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. Glapi.pm Cpic3270.pm Cpic.pmCpic7800.pmCpicDku.pm

Going the Microsoft way Windows only, Intel only COM+ Take the Glink for Windows API, make a COM+ object Already delivered as a beta release of Glink Professional

Going another way Multiple platforms, multiple OS Java API Take Glink for Java Already delivered as a beta of release 6.2 Take the Java API Produce Enterprise Java Beans

In terms of J2EE standards Glink for Java API becomes a tool for developing connectors Connectors encapsulate heterogeneous Enterprise Information System access in a standardized way Bull and G&R will in cooperation develop 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
