Using
Enterprise Developer, you can generate the following types of CICS Web services:
- Provider
- A provider CICS Web service is made available over the Web to a requester, which can be another Web service or a SOAP request. The requester makes one or more requests to the provider, which then returns the requested data back to the requester.
- Using
Enterprise Developer, you can create a provider CICS Web service using either the bottom-up or the top-down method.
- Bottom-up method
- To use the bottom-up method, you start with an existing CICS COBOL application, and expose its functionality as a Web service suitable for access across the Web.
From the original application,
Enterprise Developer generates a WSDL file that describes the application, and a WSBIND file that maps the input and output of the application to the Web service.
If you want to make your provider Web service available to multiple clients via the Web, you can distribute the generated WSDL file from which requester clients can be generated. Organizations that distribute WSDL files for this purpose are called Web service provider agents.
- Top-down method
- To use the top-down method, you start with a WSDL file that describes an existing web service. From the WSDL file, a set of COBOL language structures are generated which are used to create a new application.
From the WSDL file,
Enterprise Developer generates a provider program to process requests, and a WSBIND file that maps the input and output of the application to the Web service.
- Requester
- All CICS Web service requesters
(also called clients)
are created using the top-down method. You start with a WSDL file such as one supplied by a Web service provider agent, that describes the underlying CICS application. From the WSDL file,
Enterprise Developer generates a CICS client application to launch the Web service requester, and to receive returned data. In addition,
Enterprise Developer generates a WSBIND file that maps the input and output of the application to the Web service.
