Have tried to use public wsdl for testing Web service with JMeter 2.2. The JMeter user guide suggests going to http://www.xmethods.net/ for public web services to try.
When I enter any of these into WSDL URL field (e.g. EuroCv service http://api.eurocv.eu/euroserver.php?wsdl) when defining a WebService(SOAP) request I get error message 'The WSDL was not valid, please double check the url'. Yours, DavidS
