You would first need to connect to IS server. From the standalone get the context. Then use connect method to connect to the server.
Signature is connect(“server IP:port”,“username”,“password”);
Then u can use Service.doInvoke to call the flow service
its signature is
Service.doInvoke(“full path to service”,“service name”, “IData as input”);
