Introduction to Web Services with CICS

Recommended Duration:
2-3 Days
Service Oriented Architecture (SOA) is a standards-based architecture where business processes are represented by one-or-more independent services that may be orchestrated into new applications as needed. Today Web Services provide the backbone components of SOA for most organizations. This course introduces the core concepts of SOA and Web Services. Participants will learn to work with CICS and COBOL to use existing Web Services and to create Web Services for others to use. Class exercises will use WSDL (Web Services Description Language) and SOAP to process Web Services. RESTful Web Services will also be explored.
Experienced CICS programmers and designers needing to learn how to create and use Web Services.
Students must have CICS and COBOL experience or must have completed CICS and COBOL training. Experience with XML and/or JSON is very useful but not required..
