Hi Rishi, Yes, you are using the command-line argument correctly. I just tried stopping some instances ( their statuses were FINISHED) and it works for me.
I tried : ./wmgr-client --url http://localhost:9001 --operation --stopWorkflowInst --id a2741f59-e631-11e0-ab26-03f35922ef75 The messages: WARNING: WorkflowEngine: Attempt to stop workflow instance id: a2741f59-e631-11e0-ab26-03f35922ef75, however, this engine is not tracking its execution Oct 12, 2011 4:49:34 PM sun.net.www.protocol.http.HttpURLConnection getInputStream FINE: sun.net.www.MessageHeader@6aa6aeed5 pairs: {null: HTTP/1.1 200 OK}{Server: Apache XML-RPC 1.0}{Connection: close}{Content-Type: text/xml}{Content-Length: 121} Successfully stopped workflow: [a2741f59-e631-11e0-ab26-03f35922ef75] So, I'm not sure whats causing your NullPointerException.
