Ports

• A port defines an individual endpoint by specifying a single address for a binding.
• It is the network location where the web service is implemented.
• The name attribute provides a unique name among all bindings defined within in the enclosing WSDL document.
• The binding attribute (of type QName) refers to the binding using the linking rules defined by WSDL.
• A port must not specify more than one address.
• A port must not specify any binding information other than address information.

<wsdl:service name="HelloService">
  <wsdl:port name="HelloPort"
    binding="tns:HelloWorldBinding"><!--defined by a previous binding-->
    <soap:address location="http://localhost:8080"/>
  </wsdl:port>
</wsdl:service>

• A service can also define multiple ports, each of which may implement a different binding at a different network location.
