This course has been designed for applications and systems programmers who require practical skills in implementing and using CICS WEB SUPPORT. This hands-on class will take delegates through the various components of CWS, HTML, HTTP, SOAP, XML, HTTPS, JavaScript, form design and much more. By the end of the course attendees will have written a number of Web based CICS applications using the CWS APIs using CICS both as a Client and a Server.

This course is only available for one-company, on-site presentations.

Objectives

On successful completion of this course you will be able to:

deploy CICS applications on the Web using CWS or CICS Web Services
build and Debug both CWS and CICS Web Services applications
enable CICS to deliver various media types, with support for caching
exploit the FORMFIELD API to parse incoming data.

Who Should Attend

CICS systems programmers and applications programmers.

Prerequisites

At least one year's experience of CICS application or systems programming recommended. In addition exposure to HTML, SOAP/XML in any environment would be an advantage.
