* TODO To change the template for this generated file go to
* Window - Preferences - Java - Code Style - Code Templates

* Generates a simple 'Hello World' PDF file.
* @author blowagie
public class pdfgenerator {
     * Generates a PDF file with the text 'Hello World'
     * @param args no arguments needed here
     public static void main(String[] args) {
          System.out.println("Hello World");
          Rectangle pageSize = new Rectangle(916, 1592);
                    pageSize.setBackgroundColor(new java.awt.Color(0xFF, 0xFF, 0xDE));
          // step 1: creation of a document-object
          //Document document = new Document(pageSize);
          Document document = new Document(pageSize, 132, 164, 108, 108);
          try {
               // step 2:
               // we create a writer that listens to the document
               // and directs a PDF-stream to a file
               PdfWriter writer =PdfWriter.getInstance(document,new FileOutputStream("c:\\weeklystatus.pdf"));
               writer.setEncryption(PdfWriter.STRENGTH128BITS, "Hello", "World", PdfWriter.AllowCopy | PdfWriter.AllowPrinting);
//               step 3: we open the document
                         document.open();
               Paragraph paragraph = new Paragraph("",new Font(Font.TIMES_ROMAN, 13, Font.BOLDITALIC, new Color(0, 0, 255)));
               POIFSFileSystem pofilesystem=new POIFSFileSystem(new FileInputStream("D:\\ESM\\plans\\weekly report(31-01..04-02).xls"));
               HSSFWorkbook hbook=new HSSFWorkbook(pofilesystem);
               HSSFSheet hsheet=hbook.getSheetAt(0);//.createSheet();
               Iterator rows = hsheet.rowIterator();
                              while( rows.hasNext() ) {
                                   Phrase phrase=new Phrase();
                                   HSSFRow row = (HSSFRow) rows.next();
                                   //System.out.println( "Row #" + row.getRowNum());
                                   // Iterate over each cell in the row and print out the cell's content
                                   Iterator cells = row.cellIterator();
                                   while( cells.hasNext() ) {
                                        HSSFCell cell = (HSSFCell) cells.next();
                                        //System.out.println( "Cell #" + cell.getCellNum() );
                                        switch ( cell.getCellType() ) {
                                             case HSSFCell.CELL_TYPE_STRING:
                                             String stringcell=cell.getStringCellValue ()+" ";
                                             writer.setSpaceCharRatio(PdfWriter.NO_SPACE_CHAR_RATIO);
                                             phrase.add(stringcell);
                                        // document.add(new Phrase(string));
                                                  System.out.print( cell.getStringCellValue () );
                                                  break;
                                             case HSSFCell.CELL_TYPE_FORMULA:
                                                       String stringdate=cell.getCellFormula()+" ";
                                                       writer.setSpaceCharRatio(PdfWriter.NO_SPACE_CHAR_RATIO);
                                                       phrase.add(stringdate);
                                             System.out.print( cell.getCellFormula() );
                                                       break;
                                             case HSSFCell.CELL_TYPE_NUMERIC:
                                             String string=String.valueOf(cell.getNumericCellValue())+" ";
                                                  writer.setSpaceCharRatio(PdfWriter.NO_SPACE_CHAR_RATIO);
                                                  phrase.add(string);
                                                  System.out.print( cell.getNumericCellValue() );
                                                  break;
                                             default:
                                                  //System.out.println( "unsuported sell type" );
                                                  break;
                                   document.add(new Paragraph(phrase));
                                   document.add(new Paragraph("\n \n \n"));
               // step 4: we add a paragraph to the document
          } catch (DocumentException de) {
               System.err.println(de.getMessage());
          } catch (IOException ioe) {
               System.err.println(ioe.getMessage());
          // step 5: we close the document
          document.close();
My Input from MS-Excel file is:

                                   The issues i'm facing are:
When it is reading a row from MS-Excel it is writing to the .pdf file from last cell to first cell.( 2 cell in 1 place, 1 cell in 2 place like if the row has two cells with data as : Name of the Intern: Kesavulu Reddy then it is writing to the .pdf file as Kesavulu Reddy Name of Intern)
and the second issue is:
It is not recognizing the date format..it is recognizing the date in first row only......
Plz Tell me wht is the solution for this...
