An exception is thrown in the first line of the RpcServlet.process method:
JSONObject req = new JSONObject(body);
The message of the exception says
org.json.JSONException: A JSONObject text must begin with '{' at
character 1 of [{"method":"gadgets.metadata","id":"gadgets.metadata",
"params" ... "groupId":"@self"}}]
If I remove the '[' and '[' in the JSON string in the debugger (the array
has only a single element anyways), I got another exception:
org.json.JSONException: JSONObject["context"] not found.
So it seams the actual request is incorrect. Something with a "context"
field is expected but not sent.
Any ideas?
