[jboss-user] [jBPM] - jBPM 5.4 : Signal Event and VariableName

wishmaster7 [https://community.jboss.org/people/wishmaster7] created the discussion "jBPM 5.4 : Signal Event and VariableName" To view the discussion, visit: https://community.jboss.org/message/795177#795177 -------------------------------------------------------------- Hi all, I am a beginner with jBPM and I need some help with the signal event; all I have found in the documentation (and in the web chat) is something like : VariableName: The name of the variable that will contain the data associated with this event (if any) when this event occurs. And this doesn't help much... So I have created a basic example with a start node, then a AND gateway which waits for the signal event. I'm working with jBPM REST webservices; first I call : POST: http://localhost:8080/gwt-console-server/rs/process/definition/myProcess/... and in the json return, I get the process instance id (in this example: 57). Then I call : POST: http://localhost:8080/gwt-console-server/rs/process/tokens/57/transition?... and this pefectly triggers the signal event. But I want to pass parameters, and I think the "VariableName" of the signal event is suitable for that. So I have the "woId" variable, but its value is always null. Here is, in my Java application, the code I use to call the POST webservice: private String requestPostService() throws Exception { String url = "http://localhost:8080/gwt-console-server/rs/process/tokens/57/transition?signal=receiveInitData";         // here is my map with the parameter I want to pass to the jBPM process     List<NameValuePair> formparams = new ArrayList<NameValuePair>();     formparams.add(new BasicNameValuePair("woId", "testValue"));         HttpPost httpPost = new HttpPost(url);         UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formparams, "UTF-8");         httpPost.setEntity(entity);         HttpClient httpClient = new DefaultHttpClient();         HttpResponse response = httpClient.execute(httpPost);    // the getRequestString() method is parsing the response         return this.getRequestString(response);     } And in attachement, the process BPMN file. I don't know what is missing; in the console, it's printing: Init data... null "Init data" is the string called in "Init Data" task; null is the value of my variable. Someone has an idea? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/795177#795177] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
