GDT V5 Web Services

CGI (Common Gateway Interface) (Requires GDT V5.0)

RSS – “Really Simple Syndication” – WEB feed formats (Requires GDT V5.0)

C2O interacts with Web Services through SOAP calls (Does not require GDT V5.0)

Demonstrations Submitting a Batch job through the GDT Console

via CGI Accessing RSS feed via a Batch program to return

information to a Batch Report



CGICommon Gateway Interface

Server extension that extends capabilities of Web Servers. Lets Web Clients request information from Web

Servers The process:

User fills out a form that is submitted to the Server. The Server uses the submitted information to query

a database or as input to a program. There is NO Back and Forth information between

the server and the client User must fill out the form and submit it Blank fields with incorrect information must be detected

and client asked to resubmit the form.




CGI only allows data to be input Processes the data, produces output and

terminates CGI provides the 2 way interface between the

Web Clients and Web Servers and the CGI Script is the set of commands that determine what happens when they communicate

CGI consists of the following CGI Control Tags and Field specifiers to be placed

in the HTML documents The flow of the information between client, server

and script.




Micro Focus IDE provides the tools via the Internet Application Wizard Create the HTML form and add Tags that define the

input boxes, drop-down list boxes and buttons that appear on the forms to collect input from the users

Create the CGI Script to accept the input that the end user types on the HTML form and do something with it like query a database or input to a program.

Reduces the amount of effort involved in creating server-side programs

Server-side programs can easily be generated from existing COBOL programs

RSS

RSS Document called a "feed," "web feed” or "channel” contains either a summary of content from an

associated web site or the full text makes it possible for people to keep up with web

sites in an automated manner that can be piped into special programs or filtered displays

A standardized XML file format allows the information to be published once and viewed by many different programs.

GDT V5.0 software Had to become a "RSS reader," "feed reader”.
