17 Why Web Services? Web services provide standardized access to assets for different software applications residing on disparate platforms Web service definitions provide abstract interfaces which allow for loose coupling between business components implementation can vary without affecting consumers You can reuse applications exposed as Web services in a variety of service-oriented architecture frameworks, such as a process choreographer or an enterprise service bus IBM Corporation 33 We need interfaces to talk XML.

20 Enable your IMS application as a Web Service Using the IMS SOAP Gateway For each application: 1. Generate XML Converters, WSDL and correlator file using RDz 2. Compile the XML Converter and link it to IMS Connect STEPLIB dataset 3. Deploy WSDL and correlator (.xml) file to IMS SOAP Gateway RDz set the following properties in the correlator file by default: Adapter type = IBM COBOL XML Adapter Program name = RDz XML converter driver name (e.g. IMSPHBKD) 2007 IBM Corporation 39 RDz and IMS SOAP Gateway 2007 IBM Corporation 40 helene.lyon@fr.ibm.com 20
