You really need to spend some more time writing down a detailed explanation of your problem. The listing of some XML on its own means absolutely nothing.

The issue is i have a login system all worked out i just need it so once a user has logged in they can they be taken to the formatted XML Array with all the users data to display for interest

The issue that im having is being able to have the XML generate on login

Hi,

i want to convert a cmyk type image into RGB Image.
if i use the below code the conversion happens but the image is not displaying properly.i can see block strike-through codes in my output image. any other way to convert CMYK to RGB.

Java

java.util.Iterator<ImageReader> readers = ImageIO.getImageReadersByFormatName("JPEG");
               ImageReader reader = null;
               while(readers.hasNext()) {
                   reader = (ImageReader)readers.next();
                   if(reader.canReadRaster()) {
                       break;
                   }
               }

               //Stream the image file (the original CMYK image)
               ImageInputStream input =   ImageIO.createImageInputStream(fromFile);
               reader.setInput(input);

               //Read the image raster
               Raster raster = reader.readRaster(0, null);

               //Create a new RGB image
               BufferedImage bi = new BufferedImage(raster.getWidth(), raster.getHeight(),BufferedImage.TYPE_INT_RGB);

               //Fill the new image with the old raster
               bi.getRaster().setRect(raster);
           System.out.println("\n\n\n   bi.getColorModel().getColorSpace().getType()\n\n "+bi.getColorModel().getColorSpace().getType());



           //  BufferedImage bi = ImageIO.read(toFile);
               int colorSpaceType = bi.getColorModel().getColorSpace().getType();

                if( colorSpaceType == ColorSpace.TYPE_CMYK)
                {
                    System.out.println("\n\n\n is CMYK image \n\n\n");
                }
                else if(colorSpaceType == ColorSpace.TYPE_RGB)
                {
                System.out.println("\n\n\n is RGB image \n\n\n");
                ImageIO.write(bi, "JPEG", new File("d:\\hi.jpg"));

                }

1. Pleas indent your code and put it between <pre> tags for readability, thus

Java

public void stop1()
{
    this.player.close();
}

2. Give proper details of your problem.

when i play an mp3 file then if i want to pause that song for some time then i can't i can only play and stop the song in this code

Rather than just repeating your original post, it would be helpful if you followed my previous suggestions. It is extremely difficult to read your code from that unformatted listing, and I cannot find a method anywhere that handles a Pause command.

I'm getting two values for my salt

This is my code

Java

private static String getSalt() throws NoSuchAlgorithmException, NoSuchProviderException
{
    SecureRandom sr = SecureRandom.getInstance("SHA1PRNG");
	//SecureRandom sr = new SecureRandom();
    byte[] salt = new byte[8192];
    sr.nextBytes(salt);    
    return salt.toString();
   
}

and when I save it in my database
my code

Java

PS.setString(1, User);		
		PS.setString(2, getSalt());
		PS.executeUpdate();		
		System.out.println(" Salt :"+getSalt());

I get different value..why?

I'm salting String asdf

VB

 Database value [B@2fc396df 
Printed value [B@5199c9ac

salt.toString();

That doesn't do what you think it does. It prints the object reference not the contents.

By the way, your function createSalt() creates a new salt every time you call it!
When you want to compare the original value and the database value, you hat to write the salt into a variable, then set it to your object, write to database, then retrieve from the database.

public void run(){
for(int i=0;i<totalThread;++i){

Thread x=new Thread(new RequestProcessor(documentRootDirectory,indexfileName));
x.start();

}

System.out.println("coonection accepted"+server.getLocalPort());
System.out.println("Dokumen root"+documentRootDirectory);

while(true){
try{
Socket request=server.accept();
RequestProcessor.startProcessing();

}
catch(IOException ex){

}
}

}

error message from this program : method RequestProcessor can't not implemented with given types,
althaugh i have create class RequestProcessor from one package, can you help me to integrated the totalThread with RequestProcessor? the error start when i try to instance new Thread.

thx.

I showed you how to find information on reading CSV files, no doubt you can do the same for XML.

I know how to read xml file but I have a problem with this file.

How to write this code?
I have .csv file. Content of file like as follow:
A,B
B,C
A,F
F,G
G,H
B,D
I have to read this file and output should be :

Java

A _ B _ C 
|   |_ D
|_F _ G_ H

How to write this code to get this output?

You don't use swing to read a file. Look at these links[^].

For output I should use swing.
and I know how to read .csv file, but my problem is with output.
how to get that output.

That question is impossible to answer in a forum like this. Go and find some swing tutorials and learn about what features are available to hlep you format your output.
