JavaCode able to Read 1 PDF but not another PDF.

Question

Hi,
I am using itext-1.3.jar for reading PDF values through Java Program.Following is the code I used:
package A;
import java.io.ByteArrayOutputStream;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Set;
import java.util.*;
import com.lowagie.text.pdf.*;
import com.lowagie.text.pdf.AcroFields;
import com.lowagie.text.pdf.PdfReader;
import com.lowagie.text.pdf.PdfStamper;
public class ReadPDF
     static ByteArrayOutputStream bytArray = new ByteArrayOutputStream();
     public static void main(String[] args)
          int pagestotal,i=1,j=1;
          HashMap fields = new HashMap();
          try {
               System.out.println("Entered try block");
               PdfReader reader = new PdfReader("C:/ReadPDF/anthem.pdf");
               System.out.println( "Tracking reader :- " + reader ) ;
               PdfStamper stamp = new PdfStamper(reader, bytArray);
               AcroFields form = stamp.getAcroFields();
               System.out.println( "Tracking form :- " + form ) ;
               fields=form.getFields();
               System.out.println("Map is "+fields);
               Set keys = fields.keySet();
               Iterator iter = keys.iterator();
               while (iter.hasNext())
                    String key = (String) iter.next();
                    System.out.println(i + " - "+ key + " - " + form.getField(key));
                    i++;
               pagestotal=reader.getNumberOfPages();
               System.out.println("total pages = "+pagestotal);
               System.out.println("size "+fields.size());
          } catch (Exception e)
               System.out.println("Exception caught");
With this Code,I am SUCCESSFULLY able to read 1 PDF ,BUT IT FAILS TO READ DATA FROM 2nd PDF.I am really not getting where is the exact problem .Please help.
