A <port> element defines an individual endpoint by specifying a single address for a binding.
- The port element has two attributes – the name attribute and the binding attribute.
- The name attribute provides a unique name among all ports defined within in the enclosing WSDL document.
- The binding attribute 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.
Here is the 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>
