.Javaファイル。ここでエラーが発生します--->intsuccess = json.getInt(TAG_SUCCESS);

サーバーからのJsonアレイは以下のとおりです。jsonlint.comから検証しました
{
"tbl_user": {
"0": {
"id": "195",
"email": "aru@yahoo.com",
"password": "202cb962ac59075b964b07152d234b70",
"fname": "aru",
"lname": "sharma"
},
"1": {
"id": "196",
"email": "manu@yahoo.com",
"password": "202cb962ac59075b964b07152d234b70",
"fname": "manu",
"lname": "sharma"
},
"2": {
"id": "197",
"email": "rishi@yahoo.com",
"password": "202cb962ac59075b964b07152d234b70",
"fname": "rishi",
"lname": "sharma"
},
"success": 1
}
}
ここからは成功の価値が読めないと思います。このJson文字列にエラーが表示されません。助けてください。
jsonを作成するサーバー上のRESTPhpコードは
function getUsers() {
$sql = "select * FROM tbl_user ORDER BY fname";
try {
$db = getConnection();
$stmt = $db->query($sql);
$users = $stmt->fetchAll(PDO::FETCH_OBJ);
$users["success"] = 1;
$db = null;
echo '{"tbl_user": ' . json_encode($users) . '}';
} catch(PDOException $e) {
echo '{"error":{"text":'. $e->getMessage() .'}}';
}
}
