G&R web site renewed
Internet Anniversary
30
years old
1969 - 1999
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.

Commercial Internet
Took off !!!!
Telnet
FTP
E-mail
But then…..
The Web came along
GCOS over TCP/IP
Much more than Telnet
Glink sessions via Ggate
Host Links sessions (GUFT, Gspool, CPIC applications)
Local server
RFC1006 over TCP/IP MainWay or FCP7/8
PCs
Glink with Ggate and (G&R predates GTEA) with RFC1006
Host Links
UNIX or
Windows NT
Glink, Gweb, PC and
Host Links applications
FCP7
FCP8

“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…
Cpic.pm
Cpic7800.pm
Cpic3270.pm
Glapi.pm
CpicDku.pm
 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.

Going the Microsoft way

COM+
Take the Glink for Windows
API, make a COM+ object
Already delivered

Going another way

Already delivered as a
beta of release 6.2
In terms of J2EE standards
Glink for Java API becomes
a tool for developing
connectors
Connectors encapsulate

Bull and G&R will in cooperation

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…..
…and remembers the input
fields that are needed, and
the output fields marked as
the desired result
Compile the recorded Java
code as an Enterprise Java
bean
The bean duplicates the
host access sequence, using
parameters for the input
fields, and delivers the
output fields as the result
