What are different components of WSDL?

Some of the different tags in WSDL xml are:

• xsd:import namespace and schemaLocation: provides WSDL URL and unique namespace for web service.
• message: for method arguments
• part: for method argument name and type
• portType: service name, there can be multiple services in a wsdl document.
• operation: contains method name
• soap:address for endpoint URL.
