CICS TS Web Services
| Duration: 4 days |
| Participants: This course is designed for experienced CICS COBOL programmers who will be writing new COBOL CICS/TS Web Services, or wrapping and or modifying existing COBOL CICS/TS programs as Web Services. |
|
Objectives:
Upon successful completion of this course you will be able to:
- Understand HTTP 1.1 Support - Use CICS Channels and Containers - Use Web Service, SOAP, SOAP header handler - Learn some XML and WSDL - Use CICS as a Web Service Provider; CICS as a Web Service Requester - Be aware of different development approaches: development approach, bottom-up, top-down, and meet-in-the-middle - Understand Security concepts (Note: Students will not be writing security handlers.) - Be aware of SOA concepts and REST concepts (Optional, only if time permits.) |
| Overview: This course concentrates on implementing the Web Services features in CICS/TS. It discusses HTTP 1.1 support, CICS transactions acting as clients in a CICS/WEB scenario, XML, SOAP and Web Services. This course focuses extensively on WSDL, as well as how to code, test, and run CICS/TS COBOL Web Services that are Web service providers and Web service requesters. Students use CICS Web Assistant and not RDz. The focus of the course is SOAP 1.1 and 1.2, although some concepts for REST will be included if time permits. Also, if time allows, some recommendations for SOA are included. SmartBear’s SOAPUI will be used in class. Neither UDDI nor MQ is covered. Students submit JCL PROCs to prepare various components. |
| Prerequisites: Knowledge the COBOL CICS API is required, as well as basic COBOL coding experience and ability to use TSO/ISPF, and modify and submit JCL. |
| Format: Lecture and hands-on computer workshops. |
