Defining Web Service Components

A Web service is represented as a component that you can display in a component diagram. From a component diagram, you can display the Web service interface and implementation code, eventually, you can also deploy Web service components to nodes if you want to describe deployment of components into servers.

For more information on how to deploy components, see Deploying a Component to a Node.

A component can be a Web service Interface or a Web service Implementation type. You have to check the Web Service check box in the component property sheet to declare your component as a Web service.

• Web Service Component Properties
  Web service component property sheets contain all the standard component properties, and some additional tabs.
• Creating a Web Service with the Wizard
  You can create a Web service with the wizard that will guide you through the creation of the component. The wizard is invoked from a class diagram and is only available if you use the Java or the .NET family.
• Creating a Web Service from the Component Diagram
  You can also create a web service from the component diagram.
• Defining Data Types for WSDL
  WSDL uses XML Schema to define data types for message structures.
• Web Service Implementation Class Properties
  A Web service requires one implementation class. An implementation class can only be associated with one Web service component. In .NET languages, the implementation class can be generated inside the .asmx file or outside. In Java, a Web service class can have a serialization and a deserialization class.
