What exactly are you trying to achieve, please? Do you have any specific reason to use this webservice? It is an internal feature only to allow Server and Designer to share JDBC connections and I can not think of any other possible reason why you would use it.
If you want to communicate with CloverETL Server via SOAP API, use our general webservice
instead, please. And if you want to perform just basic operations like executing a graph or listing all running graphs, REST API
is even simpler to use.
I hope this helps.
