Over 14 articles, this series has shown you how easy it is to write bridge applications in which your COBOL Web Service communicates with JSON through a Service Interface, with your Client program written in your preferred language. The series concludes with a list of references to videos and help pages that you will use to consolidate and extend your knowledge as you write your own bridge applications. This is the last scheduled article in this series.

1. You should start with the 3 ? m video Bridging Two Worlds. This gives necessary context to the detail in the Help pages. Then look at the Help and Training Page. This links to overview and training videos, and all the help pages.

2. The Jazz Users' Guide are the most important Help pages. You should read Introduction to Jazz, and you might like to view the Initial Demonstration (5m video).

3. Article #3, MANASYS Jazz: Getting Started. Jazz Setup tells you how to download and configure a copy of Jazz. Quickly create initial data descriptions with Import from COBOL, Import from SQL, or Import from Easytrieve. The definitions should then be enhanced with editing: The Define Statement gives all the rules. You might also like to view the first 7-8 m of tutorial video The Jazz Language.

4. Articles #4 to 7. These deal with creating the web service in Jazz and COBOL. You should go to the Jazz Users' Guide and read relevant chapters within the section “Web Service Programming.? They include both WSDL(SOAP) and JSON(REST) services: ignore WSDL/SOAP, use only JSON, and CHANNEL communication: -?

*???????Service-Oriented Architectures and Web Services. Introduces the concepts and terminology of Service Oriented Architectures.

*???????Providing Web Services?shows you how to write a Web Service Provider.??The example programs are little more than “Hello World”, but once developed you’d have the basic knowledge to write programs providing your mainframe data (VSAM???DB2?) through a web service so that it can be displayed on a web page.

*????????Real Web Services.??Starts to deal with real problems: accessing data from VSAM or DB2, and providing it to an external program for enquiry only, or for update.

*????????Web Services and Multiple Records.??Here you learn how to write web services that handle record hierarchies (think Customer/Order) and other record collections.

*?????????Micro Focus users should also read Web Services with Jazz and Micro Focus

5. Articles 8 to 10. Read Client Programming for information on creating client interfaces for JSON web services and using them.

Bridging Two Worlds is a 3 1/2 minute overview. We intend to produce a tutorial video covering the material in these articles in sufficient detail to teach you the material of this article series.
