WSDL - <service> Element
The <service> element defines the ports supported by the web service. For each of the supported protocols, there is one port element. The service element is a collection of ports.
Web service clients can learn the following from the service element −
- where to access the service,
- through which port to access the web service, and
- how the communication messages are defined.
The service element includes a documentation element to provide human-readable documentation.
Here is a piece of code from the Example chapter −
<service name = "Hello_Service"> <documentation>WSDL File for HelloService</documentation> <port binding = "tns:Hello_Binding" name = "Hello_Port"> <soap:address location = "http://www.examples.com/SayHello/"> </port> </service>
The binding attributes of port element associate the address of the service with a binding element defined in the web service. In this example, this is Hello_Binding
<binding name =" Hello_Binding" type = "tns:Hello_PortType"> <soap:binding style = "rpc" transport = "http://schemas.xmlsoap.org/soap/http"/> <operation name = "sayHello"> <soap:operation soapAction = "sayHello"/> <input> <soap:body encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/" namespace = "urn:examples:helloservice" use = "encoded"/> </input> <output> <soap:body encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/" namespace = "urn:examples:helloservice" use = "encoded"/> </output> </operation> </binding>
