Got JSONObject text must begin with '{' error

Question

The error is last line throw JsonException

Client client = Client.create();
WebResource webResource = client.resource(baseUrl+"/jaspertemplate"); 

ClientResponse respons = webResource.accept("application/json")
           .get(ClientResponse.class);

String output = respons.getEntity(String.class);
JSONObject obj1 = new JSONObject(output.trim());

My JSON:

[
    {
        "type": "folder",
        "name": "PAM",
        "path": "C:\\home\\sameer\\sample\\PAM",
        "id": "PAM6",
        "c‌hildren": [
            {
                "type": "file",
                "name": "Country_Report_View_PAM.jasper",
                "path": "C:\\home\\‌sameer\\sample\\PAM\\Country_Report_View_PAM.jasper",
                "id": "Country_Report_View_PAM.j‌asper7",
                "children": []
            }
        ]
    }
]

[{"type":"folder","name":"PAM","path":"C:\\home\\sameer\\sample\\PAM","id":"PAM6","children":[{"type":"file","name":"Country_Report_View_PAM.jasper","path":"C:\\home\\sameer\\sample\\PAM\\Country_Report_View_PAM.jasper","id":"Country_Report_View_PAM.jasper7","children":[]}]}] My Json is this — jacob, Mar 23 '15 at 05:28
are you returning array or object from server side ? if it is array please return object instead — Naveen Ramawat, Mar 23 '15 at 05:31
I don't know your using librairy, but i recomand using gson: https://code.google.com/p/google-gson/ (free and easy to use) — Roy Shmuli, Mar 23 '15 at 05:31
Thanks for your reply guys.. from my web service i am using Gson — jacob, Mar 23 '15 at 05:41
String json = gson.toJson(strTemplateChildrens); return Response.ok().entity(json).build(); — jacob, Mar 23 '15 at 05:41
And convert the Json into String and pass the String at my client side .. — jacob, Mar 23 '15 at 05:42

You are expecting a JSONObject but it is returning a JSONArray. Please check object's validity before use. Following post can be used to check JSONObject or JSONArray: Test if it is JSONObject or JSONArray
