Captca implementation in java

The three CAPTCHA libraries I've used for Java are:

1. JCaptcha - This is the most configurable of the three, and pretty well documented. But we can't seem to get this to look right, no matter what. It also does audio and other unconventional CAPTCHAs
   
   http://jcaptcha.sourceforge.net/
2. SimpleCaptcha - This is reasonably configurable, and pretty well documented. I like the way this looks, but some people have trouble reading it.
   
   http://simplecaptcha.sourceforge.net/
3. icaptcha - This is pretty poorly documented, but shouldn't be too hard to figure out from the examples. In our tests, we found this to be more readable than the other two (can be a good thing or a bad thing, depending on your target audience)
   
   http://code.google.com/p/icaptcha/

Our apps are Spring MVC based, and it was really easy to integrate these.
We just went with what looked best to us (icaptcha).

OCR process in java

 use apire libraries

1.1 About OCR
OCR (Optical Character Recognition) is the technology that allows you to transform
images (e.g., images scanned from paper documents) into editable text-based
computer files.

package com.jnet.ocr;

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

import com.asprise.util.ocr.OCR;

public class OCRMain {

    /**
     * @param args
     * @throws IOException
     */
    public static void main(String[] args) throws IOException {
        OCR.setLibraryPath("C:/WINDOWS/system/AspriseOCR.dll");
        BufferedImage image = ImageIO.read(new File("scanned-text-100dpi.jpg"));
        System.out.println("height" + image.getHeight());
        System.out.println("width" + image.getWidth());
        System.out.println("minx" + image.getMinX());
        System.out.println("minY" + image.getMinY());

        image = image.getSubimage(75, 250, 240, 20);

        // String s = new OCR().recognizeEverything(image);

        // recognizes both characters and barcodes
        String s = new OCR().recognizeEverything(image);

        // prints the results.
        System.out.println("RESULTS: \n" + s);

    }

}

How many objects are created for a particular class how to find?

class One
{
static int count = 0;
One()
{
count++;
System.out.println("Number of Object created :"+count);
}

{
new One();
new One();
new One();
new One();
One o = new One();
}
}
