JSON parsing doubt!
My Json text is:
{{"itemLists": ["2"],"user":{"password":"pwd@103","userId":"103","userType":"SUPPLIER","username":"Clark"}}
I wrote json parser such as:
try
{
JSONObject mainouter =
new
JSONObject(result);
JSONArray ja=mainouter.getJSONArray(
"itemLists"
);
if(ja!=null
){
for(int
i=0;i
In your example, mainouter includes a table (itemLists) and a JSONObject (user). If you get the JSONObject of mainouter the same way you got the JSONArray and then you can forget everything that is not part of the user of JSONObject. It may be advantageous to give this good reading: http://java.sun.com/developer/technicalArticles/javame/json-me/

I get this error message every time I open firefox: "tote: json.parse: unexpected end of data."
Everytime I open Firefox I get this message "tote: json.parse: unexpected end of data." Otherwise everything works fine, I have not noticed any kind of functionality problems.
Thanks for the help!
Note that your list of details of the system shows that you have a user.js file in the profile folder to initialize some preferences at each start of Firefox.
The user.js file appears only if you or another software created, therefore, normally, he wouldn't be here.
You should check its contents with a text editor if you do not create this file yourself.
The user.js file is read whenever you launch Firefox and initializes the preferences to the value specified in this file, so set of preferences via user.js can be changed temporarily for the current session.

ATTENTION: nsIJSON.decode is obsolete. Use JSON.parse instead. Symptom. WHN I open a new tab, the creen goes on with my screens recorded, but none of them will load.
Try Firefox Safe mode to see how it works there.
A way of solving problems, which disables most of the modules.
(If you use it, switch to the default theme).
- You can open the mode without failure of Firefox 4.0 + by pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
- Or use the Help menu option, click restart with the disabled... modules while Firefox is running.
Do not choose anything at the moment, just use 'continue in safe mode.
To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.
If it's good in Firefox Safe mode, your problem is probably caused by an extension, and you need to understand that one.

Hi all
I use the parser JSON to parse a long string, stored in a text file. The string is a list of cities in the United Kingdom (about 1300 cities). There are approximately 47000 characters. It takes about 10 seconds on a blackberry bold 9700 to create a JSONObject to the chain.
You guys have any suggestions to improve performance?
Thank you
probably not. You can use a thread with min_priority to keep the head etc. UI, but otherwise, you will take your time, or switch to a more efficient like sqllite or similar data model.

JSON Parser file path not found
So I have a JSON file from which I am trying to retrieve data, but I can't get the correct path of the file. I use Unflatten of JSON
The JSON string looks like this:
{"latitude":32.78,"longitude":-96.81,"timezone":"America/Chicago","offset":-5,"currently":{"time":1478744444, "summary":"Mostly cloudy"},"minutely":{},"hourly":{"summary":"Rain","icon":"rain","data":[{"time":1478744555,"summary":"Cloudy","temperature":60.55,"windSpeed":14.5}{"time":1478745555,"summary":"Mildly cloudy","temperature":60.00,"windSpeed":13.5}]},"daily":{},"flags":{}}
There is much more in the actual string, but the important part is the hourly data, which are divided into 48 different pieces for 48 hours. I know I can get the 'time' and 'summary' part 'currently', but whenever I try to get something 'all hours' or ' schedule / data "I get this error:" LabVIEW: the path is not found in the JSON string. "
I can get the info 'currently' like this: 
it is just to show that the path is very simple, just "currently / hour ' and it works.
But trying to do the same thing does not work with the array of objects:
I also tried to make the type and by default is the same as what is in the elements of the array 'features', but the error is still the same.
So is it possible to separate each of the time slices in the 'data', or to extract what is in the block of 'time' and then use the function JSON Unflatten on it again?
You must include the array index in your path. The hooks in the json data indicate a table, to do something like the following:
For some reason, I'm getting a "LabVIEW: the JSON string is not valid." Error in JSON strings must be encoded in UTF - 8 and must conform to the JSON grammar. ", but that might just be because of her copy + paste of the JSON string.
Oh... missing the comma between the elements of the array. Add a comma after the wind speed':14.5} at the end of the 6th line.
In your second example, you should have the cluster in an array of clusters containing 3 digital items - while must have worked. It takes a little getting used to understand how to convert JSON structures clustered LV.

Scalar JSON parsing of the HTTP Client
Hello everyone, I have been using the HTTP Client to call an API via HTTP GET to get a JSON string. I want to be able to analyze all the information and data that I get in this JSON string. I think that the JSON string I get is a JSON scalar and not an array or an object. It looks like a combination of table and object. Here is an example of the data that I'll be back:
{"Measurements": [{"voltageRMS": 120.12,: 121044.295 ' currentRMS ': 11.85, ' totalEnergy '}], 'code': 'OK', 'time': 7}
I tried to use "JSON unflatten" but it did not work. I continued to get several errors. Error 1 was that this path not found in JSON when I put in currentRMS as a string table in the way even though I am following the directions for help. Error 2, is that I have a different type of data between JSON and LabView. In one of the LabView examples, it is an array JSON goes to several unflatten JSON and it works fine (as long as it's a JSON array). However, once I use my JSON scalar, the JSON unflatten function no longer works.
So, I downloaded some addons and used the JSON API in the LAVA. I used the JSON API for scalar but kept on getting errors. One of these errors is that the vi is unable to analyze the data. I tried with several vi analysis (i.e. timestamp). I tried to use the JSON array and thus got errors.
Any advice would be greatly appreciated, I'm completely stuck. Help, please. Thank you.
Even if you have only 1 point in the array, the field of 'measures' is a JSON array - noted in square brackets. Don't forget - the cluster should match the JSON data structure you are trying to decode exactly (not the format you expect!).
With JSON Unflatten - you can either convert the entire string JSON, or you can draw the elements individually on the way (for example, an XPath in XML).
Here are some examples:
In the top example - I unflatten the entire cluster and this will give an array of measures. In the second example, I only remove the "0th" of the measure as a scalar array. Had not added the '0' in the path of the table, the data type / output would have been an array of measures.

now how can I Prase, there are two tables?
you call http://www.blackberry.com/developers/docs/7.1.0api/org/json/me/JSONArray.html#getJSONArray (int) on the index 0 and 1, in this case, to get the Sub-tables.
and so on until call you getJSONObject to get a single item.

Does everything with JSON of QML
Hello
Just trying to decide what type of template to use for the list, I wanted to do.
It's true that I can't fully implement JSON in its entirety in QML? that is sort of the key (and everything else 100%) in QML, no C++ at all. (I have a JSON file I created)
In the examples I see, to do a minimum implementation in C++ and more QML.
Otherwise, I can use XML purely in QML but will not get the features of sort etc..
Is everything is OK?
I just noticed tonight that the 'global' Javascript object, in the environment of waterfalls QML, has a JSON object in it.
This seems to be the JSON object standard ECMAscript 5 which is documented here: https://developer.mozilla.org/en-US/docs/Using_native_JSON
By using it, you could make JSON.parse (somestring) and retrieve the result of the analysis of the JSON. Similar to eval(), but probably better...
Also a JSON.stringify () has to go the other way.
These things were probably obvious to many who read this... was good news for me.

JsonDataAccess error in JSON even report it is valid
I have a problem with parsing JSON which I get from QNetworkReply. I checked on http://json.parser.online.fr/beta/ if json is valid and it is:
{
"status": 0,
"objects": [{
"id": "i_53909cc3eeafd",
"name": "picture1",
"location": [{
"x": -5,
"y": 126
}, {
"x": 266,
"y": 126
}, {
"x": 269,
"y": 396
}, {
"x": -5,
"y": 400
}]
}]
}
I use following code:
void ApplicationUI::onRequestFinished(QNetworkReply* reply) {
QString response = QString::fromUtf8(reply->readAll());
if(reply){
if(reply->error() == QNetworkReply::NoError) {
JsonDataAccess jsonDataAccess;
QVariant list = jsonDataAccess.loadFromBuffer(response);
if (jsonDataAccess.hasError()) {
DataAccessError error = jsonDataAccess.error();
qDebug() << "JSON loading error: " << error.errorType() << ": " << error.errorMessage();
return;
}
} else {
qDebug() << "Network error!";
}
}
reply->deleteLater();
}
Everyt time I receive reply jsonDataAccess shows me error:
JSON loading error: 3 : "* Line 1, Column 1
Syntax error: value, object or array expected.
"
The second problem is the fact that I am not able to access the values of this json response. I tried many possibilities and I always get empty results.
OK, the problem is now resolved. I realized that my QNetworkAccessManager I had after the line:
request.setRawHeader(QString("Accept-Encoding").toAscii(), QString("gzip,deflate").toAscii());
