- 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 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 Example Session:
<service name="HelloWorld_Service"> <documentation>WSDL File for HelloWorldService</documentation> <port binding="tns:HelloWorld_Binding" name="HelloWorld_Port"> <soap:address location="https://www.dineshonjava.com/SayHelloWorld/"> </port> </service>
The binding attributes of por element associate the address of the service with a binding element defined in the Web service. In this example this is HelloWorld_Binding
<binding name="HelloWorld_Binding" type="tns:HelloWorld_PortType"> <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="sayHelloWorld"> <soap:operation soapAction="sayHelloWorld"/> <input> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="urn:examples:helloworldservice" use="encoded"/> </input> <output> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="urn:dineshonjava:helloworldservice" use="encoded"/> </output> </operation> </binding>
