Creating an Ensemble Web Service• Because it is a Web service, it has a WSDL document (generated automatically) that describesthe Web methods available in it. The service can receive any SOAP message that conforms to theWSDL and sends SOAP responses in return.• Because it is an Ensemble business service, it is an integral part of the Ensemble production towhich you add it. Monitoring, error logging, runtime parameters, and all the rest of the Ensemblemachinery are available as usual.Note:An Ensemble Web service is not available unless the production is running (and thebusiness service is enabled).In contrast to most other Ensemble inbound interfaces, the ProcessInput method of the business serviceis not invoked automatically. This means that your Web methods must invoke this method as appropriate,passing to it the appropriate request Ensemble message and receiving an Ensemble responsemessage. You can define any message that you need.The ProcessInput method of the Web service performs required internal activities and then invokesthe OnProcessInput method of the business service, passing to in whatever Ensemble request messageit received. The OnProcessInput method is an empty callback method; you customize it to send therequest message to some destination within Ensemble.The following figure shows the overall flow of request messages:10 Using SOAP and Web Services with Ensemble
