Question

I have a web servlet that returns a json which is stored in my bb mobile app as string in json format….

Now I want to parse the string to extract values from it…
using

JSONObject jsobject = new JSONObject(jsonString);

returns an error:

json must start with {

My JSON generated is in this format

[
   {"LASTNAME":"akre","FIRSTNAME":"swapnil"},
   {"LASTNAME":"akre","FIRSTNAME":"swapnil"},
   {"LASTNAME":"akre","FIRSTNAME":"swapnil"}
]

which is corect format as verified by jsonlint.com….

Answer 1

yes, json must start with { and end with } , what you can do is you put your json array in
{}, so it will be parsed correctly. JsonLint parses the partial json as well thats why it is showing it as correct. You can try like following
