Operation -> ‘Java
Function’ The Operation defines the name of the Operation and ties the request
response messages together.
Port -> A
service is assessable on a Port. A Port
has a unique name space and binding attribute. The Port specifies the service
address. Web service can be exposed as SOAP or HTTP. The same web service can
also be exposed by multiple Ports.
SOAP example:
<port name='WeatherSoapPort'
binding='wsdlns:WeatherSoapBinding' >
<soap:address location='http://localhost/demos/wsdl/devxpert/weatherservice.asp'
/>
</port>
HTTP example:
<port name='WeatherSoapPort'
binding='wsdlns:WeatherSoapBinding' >
<http:address
location="http://localhost/demos/wsdl/devxpert/weatherGET.asp"/
</port>
Message -> Normally
two messages required i.e. input message and output message. Messages contain
zero or more <part> elements. Sample messages below
<message name='Weather.GetTemperature'>
<part
name='zipcode' type='xsd:string'/>
<part
name='celsius' type='xsd:boolean'/>
</message>
<message
name='Weather.GetTemperatureResponse'>
<part
name='Result' type='xsd:float'/>
</message>
Binding ->
‘Ties it all together’ - specifies binding(s) of each operation in the
PortTypes section
