How to get bytes?

Hay guys,
I have a file. I am trying to read the file. But i want put the file as bytes after reading, How can i do this?
this is my code
int size = 0;
FileInputStream f0 = new FileInputStream("C:/Documents and Settings/Adeel Syed/Desktop/EncDes.txt");
size =f0.available();
System.out.println("Original File Avaliable Size -> "+size);
Thanks alot in Advance

File inF = new File("C:/Documents and Settings/Adeel Syed/Desktop/EncDes.txt");
    // This is the length
    // Note: it is a long, not an int
long size = inF.length();
    // now open the stream
FileInputStream f0 = new FileInputStream(inF);There's an example of reading the contents of a file into
a byte array here: http://javaalmanac.com/egs/java.io/File2ByteArray.html

How to get byte array from jpg in resource for Image XObject?

Hi,
Does anyone know how to get an array of bytes from a jpg from resource without an external library except MFC?
The array of bytes is needed to create an Image XObject so it can be included in an appearance for an annotation.

Sounds like a standard Windows programming question, not specific to the SDK.

How to get bytes[] using jni functions

I am new to JNI and have a question. I have a java class which returns back bytes[]
I have the class jclass for the object and the jmethodid bytesMethodID which is mapped like this:
bytesMethodID = (*env)->GetMethodID(env, objcls, "bytes", "()[B");
now in the c impementation I have a stuct pointer
DESIGN_STRUCT *str= NULL;
How do I assign the bytes[] into this struct pointer? If I do the following:
str = (*env)->CallObjectMethod(env, obj, bytesMethod());
I get a "assignment from incompatible pointer type" if I change that to:
str = (*env)->CallBytesMethod(env, obj, bytesMethod());]
I get a "assignment makes pointer from integer without a cast"
My question is what JNI function do i use to get back a byte[]
Any help and pointers greatly appreciated.
Thanks,

You should use CallObjectMethod() and cast the return value to a jbyteArray. Then you need to use a function like GetByteArrayElements() to actually retrieve the individual elements in that array.

How to get Byte[] from an image object?

This are the codes that i have tried, it did an resized.jpg but the file doesnt consist of the image. My program will stream the .jpg file using fileconnection then i resize the image and created the new image using image.createRGBImage(). Lastly, i need to save the resized image as a jpeg file but i failed to do so..
byte[] jpegData = ImageByteConverter.getByteArray(image);
OutputStream out = fconn.openOutputStream();
out.write(jpegData,0,jpegData.length);
* This method converts a int-array, containing all RGB values for the image, to
* a byte-array containing all RGB values.
public static byte[] getByteArray(Image image){
// Allocate new memory for the int-array and fill the array in the getRGB method.
int[]raw = new int[image.getWidth() * image.getHeight()];
image.getRGB(raw, 0, image.getWidth(), 0, 0, image.getWidth(), image.getHeight());
byte[]rawByte = new byte[image.getWidth() * image.getHeight() * 4];// ARGB
int a, r, g, b;
int n = 0;
// loop through the int-array and get the 4 bytes of each value to the byte-array.
// since java isn't supporting unsigned bytes we need to store the ARGB values from -128 to 127
// where -128 = 128, -127 = 129 and -1 = 255
for(int i=0; i<raw.length; i++){
// Right-shift the values to fit in a byte.
int ARGB = raw;
a = (ARGB & 0xFF000000) >> 24;
r = (ARGB & 0xFF0000) >> 16;
g = (ARGB & 0xFF00) >> 8;
b = (ARGB & 0xFF);
rawByte[n] = (byte)b;
rawByte[n+1] = (byte)g;
rawByte[n+2] = (byte)r;
rawByte[n+3] = (byte)a;
n+=4;
raw=null;
return rawByte;
Thanks in advance.

you can do follwoing but not sure whether thats what you want.
Also not sure whether its the best way.

How to get a string or byte array representation of an Image/BufferedImage?

I have a java.awt.Image object that I want to transfer to a server application (.NET) through a http post request.
To do that I would like to encode the Image to jpeg format and convert it to a string or byte array to be able to send it in a way that the receiver application (.NET) could handle. So, I've tried to do like this.
private void send(Image image) {
    int width = image.getWidth(null);
    int height = image.getHeight(null);
    try {
        BufferedImage buffImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        ImageIcon imageIcon = new ImageIcon(image);
        ImageObserver observer = imageIcon.getImageObserver();
        buffImage.getGraphics().setColor(new Color(255, 255, 255));
        buffImage.getGraphics().fillRect(0, 0, width, height);
        buffImage.getGraphics().drawImage(imageIcon.getImage(), 0, 0, observer);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        JPEGImageEncoder jpeg = JPEGCodec.createJPEGEncoder(stream);
        jpeg.encode(buffImage);
        URL url = new URL(/* my url... */);
        URLConnection connection = url.openConnection();
        String boundary = "--------" + Long.toHexString(System.currentTimeMillis());
        connection.setRequestProperty("method", "POST");
        connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
        String output = "--" + boundary + "\r\n"
                      + "Content-Disposition: form-data; name=\"myImage\"; filename=\"myFilename.jpg\"\r\n"
                      + "Content-Type: image/jpeg\r\n"
                      + "Content-Transfer-Encoding: base64\r\n\r\n"
                      + new String(stream.toByteArray())
                      + "\r\n--" + boundary + "--\r\n";
        connection.setDoOutput(true);
        connection.getOutputStream().write(output.getBytes());
        connection.connect();
    } catch {
}This code works, but the image I get when I save it from the receiver application is distorted. The width and height is correct, but the content and colors are really weird. I tried to set different image types (first line inside the try-block), and this gave me different distorsions, but no image type gave me the correct image.
Maybe I should say that I can display the original Image object on screen correctly.
I also realized that the Image object is an instance of BufferedImage, so I thought I could skip the first six lines inside the try-block, but that doesn't help. This way I don't have to set the image type in the constructor, but the result still is color distorted.
Any ideas on how to get from an Image/BufferedImage to a string or byte array representation of the image in jpeg format?

Here you go:
private static void send(BufferedImage image) throws Exception
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    ImageIO.write(image, "jpeg", byteArrayOutputStream);
    byte[] imageByteArray = byteArrayOutputStream.toByteArray();
    URL url = new URL("http://<host>:<port>");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    OutputStream outputStream = connection.getOutputStream();
    outputStream.write(imageByteArray, 0, imageByteArray.length);
    outputStream.close();
    connection.connect();
    // alternative to connect is to get & close the input stream
    // connection.getInputStream().close();
}

How to get the number of bytes at TCP port

Hi all,
How to get the number of bytes to read at the TCp port...as someone had suggested in some forum we do read the number of bytes first and then pass this...
but we get a problem when we have FF data in this...because then it sends 2 FF data...and cause of this we skip the last data...is there any solution for the same?

Hi
In LabVIEW you don't have the same property as in serail port.
You havn't "Byte at TCPIP port".
if you developp a protocol, one soltion, is to send the size to read.

How to get the file size (in bytes) for all files in a directory?

How to get the file size (in bytes) for all files in a directory?
The following code does not work. isFile() does NOT recognize files as files but only as directories. Why?
Furthermore the size is not retrieved correctly.
How do I have to code it otherwise? Is there a way of not converting f-to-string-to-File again but iterate over all file objects instead?
Thank you
Peter
java.io.File f = new java.io.File("D:/todo/");

How to get password as string back from encrypted password byte array.

Hi All,
I am storing encrypted password and enc key in the database.(Code included encryptPassword method for encryption and validatePassword method for validating of password). Problem is that for some reason i need to show user's password to the user as a string as he/she entered. But i am not able to convert the encrypted password from D/B to original String.
Tell me if any body know how to get the string password back from the encrypted password byte array after seeing my existing encryption code.
//********* Code
private Vector encryptPassword(byte[] arrPwd)
try
// parameter arrPwd is the password as entered by the user and to be encrypted.
byte[] encPwd = null;

Hi All,
I am storing encrypted password and enc key in the
database.(Code included encryptPassword method for
encryption and validatePassword method for validating
of password). Problem is that for some reason i need
to show user's password to the user as a string as
he/she entered. But i am not able to convert the
encrypted password from D/B to original String.No, you are not encrypting the password in your code, you are merely signing it.
Tell me if any body know how to get the string
password back from the encrypted password byte array
after seeing my existing encryption code.It is impossible to retrieve the original text out of a signature.
You should read up on some encryption basics in order to understand the difference between signing and encrypting. Then you can find examples of how to encrypt something here: http://java.sun.com/j2se/1.4/docs/guide/security/jce/JCERefGuide.html.
Actually there is one class specifically for keeping keys secure, KeyStore http://java.sun.com/j2se/1.4/docs/api/java/security/KeyStore.html

How to get more than 256 bytes data

hello.
I use Schlumberger 32K Card�iJava Card 2.1�j.
Please tell me how to get more than 256 bytes data from the applet in the card!!
According to JCRE specification, need to use Get Response Command.
What is Get Response command?
Do I have to write processing of Get Response command to an applet?
Or JCRE processes Get Response command?
If knows, please tell me about!!
Thanks.

Thanks for your response!!
I understand that I have to write processing of Get Response command to an applet.
But case of Schlumberger 32K card, when host send Get Response command to an applet, card reply 6F-00!?
I'm investigating now, and it seems that response is returned before applet processes Get Response command(CLA = 00, INS = C0).
Do JCRE perform the process of Get Response command?

How to get the byte[] size dynamically from the StreamMessage object

Hi all,
Using JMS, I am receiving the FDF file as StreamMessage from the queue and attaching it to the PDF file which is present in the local system.
For that, I have written the code as follows:
{color:#0000ff} Message msg = jmsTemplate.receive();
if(msg !=null && msg instanceof StreamMessage)
StreamMessage message = (StreamMessage) msg;{color}
{color:#ff6600}//hardcoded the byte array size value
{color}{color:#0000ff} byte[] bytes = new byte[{color:#ff0000}856{color}];
System.out.println("read msg="+message.readBytes(bytes));{color}
{color:#0000ff}PdfReader pdfreader = new PdfReader("D:\\Managing_Workflows_No_Comment.pdf");
PdfStamper stamp = new PdfStamper(pdfreader, new FileOutputStream("D:\\12345.pdf"));
FdfReader fdfreader = new FdfReader(bytes);
stamp.addComments(fdfreader);
{color} {color:#0000ff} stamp.close();
{color}{color:#000000}The above code is working fine except with the hardcoded of {color:#ff0000}byte array{color}{color:#ff0000} size value{color} which is given in {color:#ff0000}RED{color} in color.
Can anybody know, {color:#000000}*how to get the byte[] size dynamically from the StreamMessage*{color} object ?
Any help would be highly beneficial for me !!!!
Thanks and Regards,
Ganesh Kumar{color}

When you create your stream message you could add an property to your message, something like streamSize that would contain the number of bytes in your stream message. Then you could get this property from the message before declaring your array.

How to get the table of value field? and can we expand the technical limits

Dear
I have created value field in COPA with KEA6. And now, I need the table which the value fields are saved. Yet, I have tried a lot to find it and get failure? Can any guy help me? Please tell me how to get the table of a value field.
And another question is that, can we extend the technical limits for the number of value field for ECC6.0?
We have a note for R.4.x Please see below:
OSS note 160892
You can display the length of a data record using Transaction KEA0 ('Maintain Operating Concern'). After you have navigated to the 'Characteristics Screen' or to the 'Value field Screen' choose menu path 'Extras -> Technical Limits'.
The maximum displayed here under 'Length in bytes on the DB' is the maximum length permitted by the Dictionary. The reserve required for the release upgrade must be subtracted from this value.
To increase the allowed number of the value fields, increase the value that is assigned to field ikcge-bas_max_cnt (FORM init_ikcge_ke USING fm_subrc, approx. line 165) in Include FKCGNF20. It specifies the number of the possible value fields. The corresponding part of the source code is attached to the note as a correction.

how to extend the limit of value numbers? please see the original question.

How to get the values of the objects inside an object??

Hi,
I am trying to write code to display name and memory usage of all session attributes, in a recursive way.
I suppose reflection is needed here, but I cant figure out how to get the values of the objects inside an object...
private void handleIt(String attributeName, Object attributeValue) {
     boolean isPrimitiveOrNull = ((null == attributeValue) ||
          (attributeValue.getClass().isPrimitive()));
     if (isPrimitiveOrNull) {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "}");
     } else {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "{");
          Field[] fields = attributeValue.getClass().getDeclaredFields();
          int lim = fields.length;
          String name;
          Object value = null;
          for (int i = 0; i < lim; i++) {
               name = fields.getName();
               //LOOK AT THIS LINE: !!!!!!!!!!!!!!!!!!!!!!!!!!!
               value = fields[i].get(obj); //I don´t know what 'obj' should be??
               handleIt(name, value);
          sb.append("}");
Any suggestions will be greatly appreciated...

I realized that massive int objects called MAX_VALUE, MIN_VALUE and SIZE where causing the StackOverflow, so I removed them from the analysis.
This is the resultant code. But I think it isnt accurate in calculating the real size of objects being got using reflexion.
Do you or somebody have any more suggestions?

How to get peak values from SM52?

I am trying to optimize my VMC since it has a high load compared to the hardware it runs on. To do that I need the peak values of those figures shown in SM52. Do any of you know how to get those?
I have NW 7, CRM 5.0 and SP13. All I get in SM52 is "Used/Allocated" with one exeption; the number of vmc containers and that show me this: "Minimum / peak / maximum number of VMs".
Thank you!

How To Get FileType and MIME Type from a File

Hi,
I am using following ways to get FileType and MIME Type.
I am able to get file type, but I am getting MIME Type as */*
Can any one please let me know how to get MIME Type, but it should not be time consuming process.
For File Type I am using following Code:
private String getFileData(InputStream inStream) {

while (inStream.available() > 0) {
     byte[] buf = new byte[inStream.available()];
     inStream.read(buf);

raf.close();
File file = new File(filePath);
JFileChooser chooser = new JFileChooser();
String fileType = chooser.getTypeDescription(file);
file.delete();
//MIME Type I am getting from
DataHandler data = new DataHandler(new DocumentSource(inStream));
data.getContentType();
data.getContentType() is not working well in all cases.
Can any one help me on this.
Thanks in advance,
Ram.

Hi,
I am using following ways to get FileType and MIME Type.
I am able to get file type, but I am getting MIME Type as */*
Can any one please let me know how to get MIME Type, but it should not be time consuming process.
For File Type I am using following Code:
private String getFileData(InputStream inStream) {
fileName = C:\temp\temp.tiff
String filePath = Util.createTempFile(fileName);
RandomAccessFile raf = new RandomAccessFile(filePath, "rw");
while (inStream.available() > 0) {
     byte[] buf = new byte[inStream.available()];
     inStream.read(buf);
     raf.write(buf);
inStream.close();
raf.close();
File file = new File(filePath);Why do you do all above?
JFileChooser chooser = new JFileChooser();
String fileType = chooser.getTypeDescription(file);
file.delete();
//MIME Type I am getting from
DataHandler data = new DataHandler(new DocumentSource(inStream));
data.getContentType();
data.getContentType() is not working well in all cases.That's because there's no way to get MIME type of all files on all filesystems.

How to get Arabic dates in SQL*Plus?

I want to do a very simple thing.
I want to type in Arabic and Display dates in Arabic.
Instead i get ????? ??????? ????? ??????? ? ? ???????, ????? for this?
Why is this?
I then changed my Windows XP "Regional and Language Options" all to Arabic. Now, I get AR (Arabic) in my language selection bar at the bottom of the Desktop. When I choose AR I can type Arabic in Notepad. ُ
Even HERE I can type in Arabic: فغحث غخعق ةثسسشلث اثقث
But in Sql*PLus I get ????? ??????? ????? ??????? ? ? ???????, ?????
If I choose AR in SQL Plus and type in Arabic I get garbage characters?

I am not sure SQL*Plus in character mode can display Arabic characters on Windows. OTN NLS_LANG FAQ http://www.oracle.com/technetwork/products/globalization/nls-lang-099431.html#_Toc105389288 says:
>
if you are testing with "special" characters please DO use the GUI and not the "DOS box" sqlplus.exe !

SQL*Plus GUI is not available with 11G: you should use SQL Developer.
