String in JSON format does not correctly... sometimes

I use the following (in collaboration with HttpConnectionFactory) to retrieve an our API JSON array:

public class LocationAPI {
    public static String getHttpResponse(String url){
        HttpConnectionFactory connfac = null;
        HttpConnection conn = null;
        DataInputStream ds = null;
        String response = null;
        try {
            connfac = new HttpConnectionFactory(url);
            conn = connfac.getNextConnection();

            if(conn.getResponseCode() == HttpConnection.HTTP_OK){
                ds = conn.openDataInputStream();
                byte[] data = new byte[ds.available()];
                ds.read(data);
                response = new String(data);
            }else{
                //http error response code handling
            }

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return response;
    }
}

The API returns something in the sense of the following:

{
    "data": [
        {
            "city": "Des Moines",
            "business_logo_url": null,
            "name": "LOUIES FLOOR COVERING INC",
            "phone": "515-243-8608",
            "icon_url": "/site_media/categoryicons/Shopping.png",
            "zipcode": "50312",
            "special_id": null,
            "state": "IA",
            "street": "2709 Ingersoll Ave",
            "special": null,
            "lat": 41.585709999999999,
            "lng": -93.653125000000003,
            "id": 136982,
            "website_url": null
        }
    ],
    "pages": 1,
    "page": 1
}

Depending on the situation, the query could return to what any one place 50 locations. Then I am parsing out them with the following:

try {
            JSONObject responseObject = new JSONObject(response);
            JSONArray responseArray = responseObject.getJSONArray("data");
            JSONObject itemObject = responseArray.getJSONObject(0);

            responseCity = itemObject.optString("city");
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

If the answer is short enough (I tested it with one place, still trying to find a query which returns both), it works fine. If he shoots Max (50 places), it-error "org.json.me.JSONException: missing value.» 829 character of ".". When I walked through it, I took a glance at the string and it seems to download the part of the answer. Any suggestions as to what I'm missing here?

Have you tried to hit the API in a browser to see if your server is truncating the answer? In addition, you can try to use

response = new String(IOUtilities.streamToBytes(ds);

in case the length of the response of statement is not ds.available (), but everything that is currently available for reading (probably the case).

HP 8600: HP 8600 does not correct tray

Hello. I'm having trouble with my HP 8600 is not pulling from the correct tray. This is a recent problem that everything was working properly until a few days ago. I have an accessory to two tray with tray #1 used for special dimensions (photos and envelopes) and standard #2 to 8.5X11paper tray. I have the default to tray #2 and locked bin #1 in my settings (#1 on the top tray, tray # 2 down). However, when I send a print job for normal letter format, he tries to send the job to use the Tray #1. I can get around this by changing the trays, but it is a real pain and much slower. I checked all software and firmware is up to date. I hope someone has a solution for this problem.

Hi @Desertboy,

Thank you for joining the HP Forums!

I have seen your post on how your printer HP Officejet pro 8600 does not correct status bar. I'm happy to help with this problem!

Follow these steps to change the print settings by default for all printing from the desktop of Windows 8.
1. Right click or touch and hold the bottom left of the screen to open the menu. In the menu, click or tap on the Control Panel, then click on or type printers and display devices.
2. Right click or tap and hold the icon of the printer () for your printer, and then click or tap Print Preferences.
3. Select your new default print settings, and then click or tap on OK.
Source: change of print settings (Windows 8).

I would use these settings to set the default to tray 2 for plain paper. So if you want to print to Tray 1, you can change the settings manually. Or, you can add the same printer again in the devices Panel and printers and together this is the default for Tray 1 for specialty paper and rename it to 8600 (Tray 1) as an example.

Smart card reader does not correctly connect once the virtual machine is restored from sleep using the vmrum controls

Smart card reader does not correctly connect once the virtual machine is restored from sleep using the vmrum controls
Scenario is,
1. smart card reader is connected to the VM with card inserted in
2 initiate a prompt suspension of the VM toolbar
3. now to resume the virtual machine by using vmrun command into the host machine
WS t vmrun start xxx.vmx
Now, the recovery of VM but the smart card reader that was previously connected does not work properly in VM that is to say, sometimes after CV chip card reader driver is uninstalling and a few other times, chip connected to the drive is not available on a virtual computer
My requirement is after power, smart card reader can stay connected to the virtual computer with the already installed driver and the smart card.
Kindly help with this problem.
Host operating system: Victoire 2012 R2
The VM OS: win 10 x 64
Thank you!!

Dear all,

I had a work around for this problem. By adding "usb.autoConnect.device0 ="0xVID:0xPID"" this statement to the VMX file, solves this problem, that is, whenever the VM is wake-up by clicking on the link CV or using vmrun commands, it connects the unit in question automatically and it is charging correctly with his driver. Obtaining smart card detected after sleep\hibernate with no problems.

VID & PID is respective ID of the device that can be seen in the properties of the Device Manager "Device Instance path".

Round trip for formatting does not

My problem is that when I open an XML file in FrameMaker, the formatting does not use my application that I put in place. I don't know where this is controlled.
That's what I did. I made a copy of the folder Structure\xml\DITA to create Structure\xml\MyDITA. I converted my documents to DITA and updated the application model and ESD (formatting only) in the MyDITA folder. I did not the DTD.
When I save my file in XML format I get no errors, but when I open the XML file on the FM band, the formatting does not my model of the MyDITA.
When I open the selected file XML in FM and StructureTools > structured Application set and it has the value DITA_1.2_topic. When I put in MyDITA has no effect on the formatting.
What is control what application to use when the XML file is opened? I have a custom XML application that works very well. The Doctype in my XML file is:
<! Topic DOCTYPE PUBLIC "-//OASIS//DTD DITA topic / / IN" "topic.dtd".
I hope it's an easy question to answer. Thank you!
Gman

HEY gman...

Using the command set the structured Application is not "permanent", when used on an XML file. You can use it to check the application currently assigned to a file, but don't bother setting it.

You must assign the appropriate on the open file application. This is done by ensuring that you have a valid structure for your application application definition (in the definition of Application Structure file) AND ensuring that this application definition is correctly configured in the dialog box Options of DITA (section mapping of the application). It seems that the DITA 1.2 app is still selected in the Options.

In Options of DITA, select the "DITA v1.1" option, then click the button «...» "to the right of the associated drop-down list. In the mapping Manager dialog box, choose new mapping in the mapping of tag list, give it a name ("MyDITA 1.1 Mapping') and choose APP_MAPPING_DITA_1.1 from the mapping Type list. Now, in the mapping Manager dialog box, enter the doctype for your app... "section" (according to your example), then enter the name of the "MyDITA" application, then select the "CATEGORY" Type (in this case). Now, choose Add/Edit. If your application supports other types of items, you will need to add them to the list of mapping. When you are done click OK. Options of DITA, you can now select your application mapping in the list (or it may already be selected).

In theory it should "work"... you will need to exit and restart FM to do properly defined.

Yes... It is not easy or straight forward, and the docs are pretty weak.

No pressure... but have you looked in (or heard of) DITA-FMx? It simplifies the whole process considerably (although the application development is still a bit of a learning curve) and makes DITA book.

Satellite A200 does not correctly reduce or increase the volume

Hello

Our Satellite A200 is having problems with its Volume control wheel.
If I turn the wheel (on the left or in the past), it does not correctly to reduce or increase the volume level.
He jumps rather the volume level in seemingly random directions (with a preference for the volume).
Turn the wheel slowly improves responsiveness a little, but it remains quite impossible to increase or decrease the volume control that to be.

BTW, I am well aware that the volume control wheel is a wheel of puls-encoder rather than ye olde potentiometer.

-Can anyone you tell me where I can find the configuration that is responsible for this Volume control wheel?
-Which driver/firmware is attached to the order of the volume control?
-How can I determine if this is a hardware or software problem?

Advice would be welcome.

Stephan

Hello

There is no software or hardware problem.
It is a new generation of volume control.

First of all there is no mechanical limit turning right or left.
In addition, this volume controller works a little different than the old volume controllers. The volume can be increased and decreased using the fixed rate

By the way;
> Can someone tell me where I can find the configuration that is responsible for this Volume control wheel?
You can change the volume as in the sound settings that could be found in the control panel.
> Which driver/firmware is attached to the order of the volume control?
Audio driver controls the volume controller.
> How can I determine if this is a hardware or software problem?
There is no problem

Why is one of my 4 5893 Modules doesn't work does not correctly?

Hello

This is the configuration of my HW and SW:

LabView 2013 SP1

1 x cRIO 9076

4 x NI 9853 CAN Modules

CAN0 - 1000 Kbps, entry timeout = 0, OutputTimeOut = 10000, Module clock: 20 MHz

CAN1 - 500 Kbps, entry timeout = 0, OutputTimeOut = 10000, Module clock: 20 MHz

I worked on a program for a test system, where each Module 9853 control two devices (CAN0 and CAN1), the same type of systems is controlled by other 9853 3 Modules in parallel.

So basically, I use exactly the same functions for each module. So far, everything has worked correctly on module 1, but now that I started to test all other modules I have the problem that Module 3/CAN0 does not correctly read the information.

While watching the FPGA façade, I see that each 10000ms one value is read, but only on that ONE module (frames are sent every 1ms from my unit)

I tested the HW itself using the included examples and it works correctly, the only difference is that the example used only 2 Modules, one to send data and the other to receive it.

I included my FPGA program as an image, I really don't think there is a problem with my RT SW, because all the other modules are working properly. Basically, my SW FPGA bed CAN Modules and puts the information in a FIFO, if there is an error (no information), it will make a loop once more and check again.

Thanks for your help

I solved the problem, it was an error of configuration on my side.

The entry for Module3 CAN1 time-out was set up NOT as 0ms and 10000ms as I thought! , so that was my reading for DUT3 loop run only every 10000ms.

Update KB976902 now the mouse doesn't work does not correctly

I had the KB976902 recently updated on 2 of the 3 computers and 2 who got now have a mouse that does not correctly. The computer number 3 does not have the update and still works fine. All three are almost identical hardware and software and have legitimate versions of windows 7.

The problem of the mouse made play almost almost impossible. Left click crashes, lag mouse click one or two times when I I try to do a restore from the left eventually drag a shortcut of the thing, I clicked on and don't know how or why.

I did a restore on a single computer, but it did not help.
