Explain the steps of acquiring a proxy object in web services.

  • Client communicates to UDI node to retrieve a list of available web services that the client has access to.
  • Every service listed has a URI pointing to the service's DISCO or WSDL document, which is needed to access the webservice and its 'webmethod" methods.
  • After interpreting the DISCO document, follow the URI for the WSDL document related to the chosen webservice.
  • Client then adds and parses the WSDL document and creates a proxy object which can then communicate with Webservice and access its "webmethod" methods.
