Hi,
I followed the tutorial: Develop oneM2M applications to create application to test REST API. I run the MySensor.java, MyActuator.java and then run the MyManager.java.
To my understanding, MyManager.java will subscribe mysensor/data and send notification to /in-cse/in-name/mymanager.
But when I run MyManager.java, I got the following error message:
Quote:

Can anyone give me the instruction to fix this error?
Thank you.

Hi Guillaume Garzone,
Thank you! After I pull the latest version, it works!
But I found that the tutorial code has some error.
In the MyHandler class of MyActuator.java, MyManager.java and MyMonitor.java, when we want to transfer String requestBody to JSONObject, JSONObject json = new JSONObject(requestBody);
there will have the error message:
A JSONObject text must begin with '{' at 1 [character 2 line 1]
It seems that requestBody is a string with XML format, so it didn't start form '{', it start from '<'.
So then I change the code so that it can transfer XML format to JSONObject
JSONObject json = XML.toJSONObject(requestBody);
then it can works.
But there is another part seems not make sense. In the MySensor.java, it send sensorValue, which is Integer format, to my sensor/data(container). But in the MyHandler of MyManager.java, tutorial use the following code:
String con = rep.getString("con");
int sensorValue = Integer.parseInt(con);
It use the getString to get the Integer format, I think there may be some error need to be fixed.

hello Mandi,
when I test the original sample code, I get the following error message in the MyHandler of MyManager.java:
Quote:org.json.JSONException: JSONObject["con"] not a string.
at org.json.JSONObject.getString(JSONObject.java:721)
at org.eclipse.om2m.app.MyManager$MyHandler.handle(MyManager.java:100)

Did you know why will be this error message happen?
I try to print out the JSONObject rep, but it looks fine like the following:
rep:{"cs":3,"ct":"20161223T162404","st":0,"con":320,"ty":4,"ri":"/mn-cse/cin-284654618","lt":"20161223T162404","pi":"/mn-cse/cnt-795693924","cnf":"application/text","rn":"cin_284654618"}
