I get "No connection could be made because the target machine actively refused it" when I try to invoke the startSession method. I can see the WSDL in a browser so I have no trouble creating the object etc. so there seems to be no broad connection issue but it's the first time I've tried this with Alfresco. Any thoughts?
Make sure /alfresco/webserviceclient.properties is in your classpath on your client and that repository.location=http://www.yourwebsiteOrIP.com/alfresco/api is set appropriately.
