Designating web services as integration components This section describes how to register and invoke a web service as an integration component in System Manager and contains the following sections: v "Overview" v "Registering a web service" Overview Web services are self-contained, modular, distributed, dynamic applications that can be described, published, located, and invoked over the network to create products, processes, and supply chains. They can be local, distributed, or Web-based. Web services are built on top of open standards such as TCP/IP, HTTP, Java, HTML, and XML. Web services use new standard technologies such as SOAP (Simple Object Access Protocol) for messaging, and UDDI (Universal Description, Discovery and Integration) and WSDL (Web Services Description Language) for publishing and discovery. Using System Manager, you can register a web service as a component of an integration component library (ICL). The registration process lists the web service as a component under Integration Component Libraries and automatically generates the business objects that InterChange Server Express will use to communicate with the web service. You can also use System Manager to test the registered web service before deploying it to the server. Registering a web service In System Manager, use the Register a new web service wizard to register a web service. 1. To start the wizard, expandIntegration Component Libraries in the WebSphere Business Integration System view, right-click the WebServices folder, and select Register New Web Service.
