Tipper. Class byte, the bytes in the class.

Is there a method/technics to empty my class in bytes and then restore back?

I know, there is no persiststore exists. But I want to store on SD card and restore back.

Currently, I have my own procedure that will generate the text file that contains each value of the variable in the class. Perhaps there is a simple method?

close the reference on "read text file" - Ref num vs prefer class conflicts

Dear users,

Vi Analyzer asks me to close the refernce created by VI "read text file". So, I would close a refnum created by primitive VI "read text file". I used a direct wire, wiring by top and bottom of the casting, but each of them attend class conflicts (see the screenshot below). It is even possible to correctly transform the refnum (byte stream type reference) to refer (reference VI generic) and remove the refnum?

See you soon,.

several images capture and read their path to send the byte array to the web service

Hello

Have a problem when the image capture, the requirement is to open the camera and capture multiple images, and once done it should send the array of bytes to the web service, wrote the class with reader and Video Control of the code and then using the saved file to store image API, but when the user capture multiple images it replaces previous if I keep the path to say dynamic by using the date and time then how I just know what images are recently captured and their path, one time I know that the path of recently captured using new fileconnection images can read the image byte array.

Implementation of the Classes of consequence

All,

I have some doubts regarding implementing the interfaces net.rim.device.api.notification.Consequence and net.rim.device.api.synchronization.SyncConverter on OS 5.0 +.

Only two methods that I understand where startNotification and stopNotification, really.

The doubts are:

-What is the convert (DataBuffer, int, int) method supposed to do? Today I returns an instance of a new class of "Configuration" I created that implements Persistable and SyncObject, if I understand it needed. This object returns a different UID each time it is called.

-What is the method convert (SyncObject, buffer, version) supposed to do? Today, I return a fixed value.

-How is the newConfiguration (long, long, byte, int, object) method supposed to be implemented? Today I just return an instance of the same 'Configuration' new category I created.

Any help on this is appreciated, as very little is said in the docs.

Thanks in advance.

Here are the methods for serialization and deserialization, which means that you need to convert your Java objects to a stream of bytes and a stream of bytes into Java objects.

The version number is specific to your application so that he knows the format of the data. This allows the version 2 of your application to restore data from a backup of the version 1 of your application (assuming that the format of your bytestream changed between versions).

Take a look at the NotificationsDemo provided with the BlackBerry SDK in Java for an example of creating a custom notification (and use the interface of consequence).

Decryption of the output of DESEncryptorEngine using the encryption of the j2se class

Does anyone know how this can be done? I'm the encryption with the following:

        byte[] keyBytes = new byte[] { -62, 11, -39, 115, 61, -123, 91, -105 };        byte[] data = new byte[] { 90, 61, 43, 52, 81, 42, 124, 82 };        byte[] encryptedData = new byte[data.length];

        DESKey key = new DESKey( keyBytes );        DESEncryptorEngine encryptor = new DESEncryptorEngine( key );        encryptor.encrypt( data, 0, encryptedData, 0 );

        //encryptedData now equals { -27, 79, 100, 23, -113, 20, -24, -80 };

And decryption using the class encryption of the j2se as follows:

        byte[] keyBytes = new byte[] { -62, 11, -39, 115, 61, -123, 91, -105 };        byte[] encryptedData = new byte[] { -27, 79, 100, 23, -113, 20, -24, -80 };

        SecretKeySpec key = new SecretKeySpec( keyBytes, "DES" );        Cipher cipher = Cipher.getInstance( "DES/ECB/NoPadding" );        cipher.init( Cipher.DECRYPT_MODE, key );        byte[] data = cipher.doFinal( encryptedData );

        //data now equals {24, 124, -74, -35, -115, -39, -65, -87}, which is WRONG!

I tried all combinations possible of algorithm/mode/padding for Cipher.getInstance (). What I am doing wrong?

Thank you

Too bad, I was misinterpretting as the keys in the way which were used.

I have read and watched videos about the creation of an object of a class and calling its method in a different class. I'm still confused on how to do it properly. By using the code below if someone can explain how to properly call the method of objects from my hand.

Huh? You have NOT posted any 'hand' or any 'method of objects '.

If you need help with the code, you need to view the code.

The Java tutorials has dozens of trails "Classes and objects": what they are, how to create and how to use them.

https://docs.Oracle.com/javase/tutorial/Java/javaOO/classes.html

1. create an instance of a class

2. call to one or more of the public methods of this class

If the class has public static methods, you don't need to create an instance first.

I suggest that you work your way through these tutorials. They include the WORKING example code.

Get the network traffic in bytes
I try to get the number of bytes to pass by the network interface.

The code I use is:

String [] interfaceList = this.proxy.getNetInterfaceList ();
a long time in = 0L;
long out = 0L;

for (String inteface: interfaceList) {}
log. Debug (inteface);
NetInterfaceStat netsstat = this.proxy.getNetInterfaceStat (inteface);
in += netsstat.getRxBytes ();
on += netsstat.getTxBytes ();
}

I'm not sure that I do it well, because the figures are not updated often. For example, I download a movie from youTube and the number does not change. I have to wait 30 seconds before it changes. Is the resolution of a minimum amount of time (on Windows 2000 Pro) is 30 seconds?
Hi James,

I saw this.proxy in your code, guess that is an instance of SigarProxyCache? This class is a wrapper for caching the values returned by the underlying class of Sigar, 30 seconds by default. You can change this value by default, but it seems you'd be better of just using the new Sigar() straight-up instead of the ProxyCache.

It should have read GET_FILE stream with personalized service in the java class
Hi all

Once I run service GET_FILE with in the java class of a custom service, how can read the stream with bytes (content).
I cannot stream content of the DataBinder object or any other. I have not found any method of DataBinder to read the stream of content.

Please help playback of streams of content of a java class personalized service?

Thank you in advance.
Hello

In a service context, here's how retrieve the content as a stream:

IdcFileDescriptor d = this.m_fileUtils.createDescriptorForRendition (this.m_binder, FileStoreProvider.R_WEB);
InputStream in = this.m_fileStore.getInputStream (d, null);

The binder must contain the information (metadata) to identify the document to be retrieved.

Problem using the pixel format indexed bytes in the PixelWriter setPixels method

I'm trying to build a byte array and set it on a WritableImage using the PixelWriter setPixels method.

If I use a RGB pixel format, it works. If I use a byte indexed pixel format, I get a NPE.
Stride etc should be fine if I'm not mistaken.

If there is no solution, maybe someone knows a solution? We chose to use the format indexed due to the size of the data / performance reasons.

You have found a bug in the platform, filed against the project to-online http://javafx-jira.kenai.com to your sample code and a link to this forum question.
Byte indexed pixel formats seem like a feature never completely (or maybe even any) implemented for me.

The PixelFormat type uses your unsuccessful case is (PixelFormat.Type.BYTE_INDEXED):

PixelFormat byteIndexedFormat = PixelFormat.createByteIndexedInstance(colorPalette);
System.out.println(byteIndexedFormat.getType());

Here are the valid PixelFormat types =>
http://docs.Oracle.com/JavaFX/2/API/JavaFX/scene/image/PixelFormat.type.html

BYTE_BGRA
The pixels are stored in adjacent bytes with the non-premultiplied components stored in order of increasing index: blue, green, red, alpha.
BYTE_BGRA_PRE
The pixels are stored in adjacent bytes with the premultiplied components stored in order of increasing index: blue, green, red, alpha.
BYTE_INDEXED
The pixel colors are referenced by byte indices stored in the pixel array, with the byte interpreted as an unsigned index into a list of colors provided by the PixelFormat object.
BYTE_RGB
The opaque pixels are stored in adjacent bytes with the color components stored in order of increasing index: red, green, blue.
INT_ARGB
The pixels are stored in 32-bit integers with the non-premultiplied components stored in order, from MSb to LSb: alpha, red, green, blue.
INT_ARGB_PRE
The pixels are stored in 32-bit integers with the premultiplied components stored in order, from MSb to LSb: alpha, red, green, blue.

As for a WritableImage native pixel format is not the same that you use the pixel format, the JavaFX platform needs to do a conversion while reading pixels in a format and write it in another format. To do this, he must be able to determine a PixelGetter for your PixelFormat (the PixelGetter is an internal thing, API not public).

And here's the source determines the PixelGetter for a given type of PixelFormat:

132         return null;

As you can see, the BYTE_INDEXED format is not supported, and null is returned instead... it is the source of your NullPointerException.

How to access the BitmapData instance on the class that extends the charger?

Hello. I use Flash CS6 to create an AIR application that loads an image from the computer, and then a pixel counts using its bitmap data.
MyImg is a class that represents the loaded image.
package com.utils {}
import flash.display.Loader;
SerializableAttribute public class extends {charger MyImg
public void MyImg (): void {}
}
}
}
In my main class I manage the selection of files and loading.
private var _myImage:MyImg = new MyImg();
private var _file:FileReference;
private var _fileTypes:FileFilter = new FileFilter ("Imagens: (*.jpeg, *.jpg, *.gif, *.png)", "*.jpeg;") *.jpg; *.gif; *.png");
When the user clicks on a "load image" button on the stage, it calls loadMyImg().
public void loadMyImg($e:MouseEvent):void {}
chooseFile();
}
The user then selects the file he wants to do.
private function chooseFile (): void {}
Inasmuch = new FileReference();
_File.addEventListener (Event.SELECT, fileSelected);
_File.browse ([_fileTypes]);
}
Once you have selected the file, it is loaded as a byte array.
private void fileSelected($e:Event):void {}
_File.removeEventListener (Event.SELECT, fileSelected);
_File.addEventListener (Event.COMPLETE, fileLoaded);
_File.load ();
}
When it finishes loading it loads the byte array in _myImage.
private void fileLoaded($e:Event):void {}
_File.removeEventListener (Event.COMPLETE, fileLoaded);
_myImage.contentLoaderInfo.addEventListener (Event.COMPLETE, dataReady);
_myImage.loadBytes (_File.Data);
}
Once it's done I try to use the _myImage BitmapData, but cannot...
private void dataReady($e:Event):void {}
$e.target.loader.contentLoaderInfo.removeEventListener (Event.COMPLETE, dataReady);
trace ($e.target + $e.target.content + $e.target.content.name + $e.target.content.bitmapData); Returns [object LoaderInfo] [object Bitmap] instance 155 [BitmapData object]
trace (_myImage + _myImage.content + _myImage.content.name + _myImage.contentLoaderInfo + _myImage.contentLoaderInfo.content.name); instance of [object LoaderInfo] 155 155 instance [object Bitmap] returns [object MyImg]
trace (_myImage.content.bitmapData) //compiler error: 1119 of bitmapData property possibly access not defined through a reference with static type flash.flashDisplay:DisplayObject.
error //same trace (_myImage.contentLoaderInfo.content.bitmapData)
}
I don't understand what I'm doing wrong. Instances have the same name so that they are identical. They both trace as bitmaps, yet when I didn't access it from the event I do not get the bitmapData. Can someone tell me what I am doing wrong? I need to use the bitmapData of the classroom MyImg. I guess I could create a BitmapData variable in the class and give it the value of $e.target.content.bitmapData, but I still want to know why it can't be simpler.
Thank you!

Cast _myImage.content as bitmap:

Bitmap (_myImage.Content)

initializeUpdate function of the com.ibm.jc CardManager class
Hello
I'm currently trying to create a JavaCard Applet loader and I get in trouble with the function initializeUpdate of the CardManager class. Below is the code that I write to initialize communication with the javacard/reader...
the list of all players with a card shows
readers is TerminalFactory.getDefault () .terminals () .list (State.CARD_PRESENT);.

{if (Readers.IsEmpty ())}
return;
}

establish a connection with the reader
expression = (PCSCJCTerminal) JCTerminal.getInstance ("PCSC", readers.get (0) m:System.NET.SocketAddress.ToString () .substring (15));
term. Open();
RTA = new ATR (term.waitForCard (2000));

connect to the map
System.out.println ("layout map...");
map = new JCard (term, atr, 2000);

Select Cardmanager
System.out.println ("selection of card manager...");
cardmanager = new CardManager (card, CardManager.daid);
cardmanager. Select();

installation key
Byte [] dfltKey = c2b ("404142434445464748494a4b4c4d4e4f");
cardmanager.setKey (new OPKey (1, 1, OPKey.DES_ECB, dfltKey));
cardmanager.setKey (new OPKey (1, 2, OPKey.DES_ECB, dfltKey));
cardmanager.setKey (new OPKey (1, 3, OPKey.DES_ECB, dfltKey));

authenticate to cardmanager
System.out.println ("authenticate to the Manager of the map... \n");
* cardmanager.initializeUpdate(1, 0,CardManager.SCP_01_05); *
cardmanager.externalAuthenticate (OPApplet.APDU_CLR);

When I run the program, everything goes well until the initializeUpdate function that throws the exception:
Exception in thread "main" java.lang.NoClassDefFoundError: com/ibm/jc/CL3
at com.ibm.jc.OPApplet.initializeUpdate (unknown Source)

Since I'm quiet new in Java, I don't know what means this exception. I think that all the parameters of the function are good since I use the same when I "manually" load Applets on the map with the same settings and it works. My JRE is 1.6 (but I also tried 1.5), and the JCOP tools version is 3.2.7.
I also tried with another card with various AIDS and SCP parameters different but I still have the same error.
I thank in advance for the future fold

The problem is not with your code, but your classpath. The card handler class seems that depends on another class that is missing when running. He is not recovered at the time of the compilation that you compile not against it. Try adding the crypto.jar located in the same location as the offcard.jar you are using.

See you soon,.

Get the null using PublicReportService_v11.wsdl bytes

Hello

I tried to use the latest PublicReportService_v11.wsdl because I want to use the function of dynamic data source. Unfortunately, when I use this wsdl instead of the original PublicReportService.wsdl, I get null on ReportResponse (getReportBytes()) bytes. However, the strange thing is that if I use PublicReportService.wsdl, everything works well. Hope you guys could help out me.

Here are the details and a code snippet:

BEEP version 10.1.3.4.1

import com.oracle.xmlns.oxp.service.publicreportservice.ArrayOfString;
import com.oracle.xmlns.oxp.service.publicreportservice.ReportResponse;
import com.oracle.xmlns.oxp.service.v11.publicreportservice.ArrayOfParamNameValue;

import com.oracle.xmlns.oxp.service.v11.publicreportservice.PublicReportService;
import com.oracle.xmlns.oxp.service.v11.publicreportservice.PublicReportServiceService;
import com.oracle.xmlns.oxp.service.v11.publicreportservice.ReportRequest;


public ReportResponse fetchReport(String reportName,
    Map<String, String> args,
    String type) throws EJBException {
    AppServProperties props = AppServProperties.getInstance();
    String reportPath =
    props.getProperty(AppServProperties.BIPUB_REPORT_PATH);
    String reportFolder =
    props.getProperty(AppServProperties.BIPUB_REPORT_FOLDER);
    String reportService = reportPath + "/services/PublicReportService_v11";
    String userName = props.getProperty(AppServProperties.BIPUB_USER_NAME);
    String password = props.getProperty(AppServProperties.BIPUB_PASSWORD);
    String locale = props.getProperty(AppServProperties.BIPUB_LOCALE);
    try {
        final ArrayList<ParamNameValue> params =
        new ArrayList<ParamNameValue>();
        for (final Map.Entry<String, String> entry: args.entrySet()) {
            ParamNameValue pnv = new ParamNameValue();
            pnv.setMultiValuesAllowed(false);
            pnv.setName(entry.getKey());
            ArrayOfString values = new ArrayOfString() {
                { // instance initializer
                    item = new ArrayList<String>();
                    item.add(entry.getValue());
                }
            };
            
            pnv.setValues(values);
            params.add(pnv);
        }
        
        //Insert report folder in absolute path of the report
        if (reportFolder != null) {
            reportName = "/" + reportFolder + reportName;
        }
        
        ArrayOfParamNameValue paramNmVals = new ArrayOfParamNameValue() {
            { // instance initializer
                item = params;
            }
        };
        
        WebServiceClient ann = PublicReportServiceService.class.getAnnotation(
            WebServiceClient.class);
        URL wsdl_url = getClass().getClassLoader().getResource(ann.wsdlLocation());
        
        PublicReportServiceService service = new PublicReportServiceService(
            wsdl_url, new QName(ann.targetNamespace(), ann.name()));
        
        PublicReportService proxy = service.getPort(PublicReportService.class);
        ((BindingProvider)proxy).getRequestContext()
            .put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
            reportService);
        
        ReportRequest reportRequest = new ReportRequest();
        reportRequest.setAttributeFormat(type);
        reportRequest.setAttributeLocale(locale);
        reportRequest.setParameterNameValues(paramNmVals);
        reportRequest.setReportAbsolutePath(reportName);
        reportRequest.setSizeOfDataChunkDownload(-1);
        
        ReportResponse reportResponse = proxy.runReport(
        reportRequest, userName, password);
        return reportResponse;
    } catch (Exception e) {
        throw new EJBException(e);
    }
}

Am I missing something?

Thank you!

Open v11.wsdl and search for the name space definitions
I think that there is something wrong with that...
Replace/oxp/service/PublicReportService by/oxp/service/v11/PublicReportService
I guess that's the cause...
I corrected reference.vb file and the client is currently working with the v11

Actual mechanism of object class as the superclass for all classes
Hi all

We know that all the classes of the java platform are the descendants of the object class. Even if we write a new class, in the absence of any explicit superclass, each class is implicitly a subclass of the object. As we expand it, not directly the object class, then how is the methods of the object are inherited from the class Sub that we wrote? How the java to maintain this hierarchy?

Can you please explain this carefully?

Thanks in advance,
Uday

Because the language is defined in this way. Compilers implement the language according to the rules of the DG JLS. Exactly how they do it is not defined. It is each compiler. As long as it respects the rules defined in the JLS to the code analysis and generate the .class file, that's all that matters. However, somewhere in the compiler's code which is about:
```
if (class has an extends clause) {
  generate corresponding bytes for extends in .class file
}
else {
  generate bytes for extends java.lang.Object in .class file
}
```
No great mystery, or philosophical question.

Tipper. Class byte, the bytes in the class.
