        String listOfItem="Item 1 \n Item 2 \n Item 3\n Item 4 \n Item 5 \n Item 6 \n Item 7 \n Item 8 \n Item 9";
        CreatingFormClass example = new CreatingFormClass(0);
        example.createPdf(RESULT1);
        FillingFormClass class1 = new FillingFormClass();
        class1.manipulatePdf(RESULT1, RESULT2,empName,listOfItem);
public class CreatingFormClass implements PdfPCellEvent {
    protected int tf;
    public CreatingFormClass(int tf) {
        this.tf = tf;
    public void createPdf(String filename) throws DocumentException, IOException {
        Document document = new Document();
        PdfWriter.getInstance(document, new FileOutputStream(filename));

        cell.setCellEvent(new CreatingFormClass(1));
        table.addCell(cell);
        table.addCell("Item List:");
        cell = new PdfPCell();
        cell.setCellEvent(new CreatingFormClass(2));
        cell.setFixedHeight(60);

Hi,
I am facing the same problem. Please help me out. I just want to read a PDF file as bytes from one location and write it as another pdf file in some other location with a diolog box prompting to open or save in the location where we want.
I executed the following code:
try{
File report =new File(location);
BufferedInputStream in=new BufferedInputStream(new FileInputStream(report));
response.setContentType("application/x-download");
response.setHeader("Content-Disposition", "attachment; filename=" + report.getName());
OutputStream outs = response.getOutputStream();
int readlen;
byte buffer[] = new byte[ 256 ];
while( (readlen = in.read( buffer )) != -1 )
outs.write( buffer, 0, readlen );
outs.flush();
outs.close();
in.close();
response.setStatus(HttpServletResponse.SC_OK);
} catch (FileNotFoundException fileNotFoundException) {
PrintWriter out= response.getWriter();
out.print("<center><Font color = 'RED'><b>"+PxDSLUtils.getApplicationProperty("label.error.CTM_E017")+"</b></Font></center>");
Though it prompts with open, save dialog box when i try to open directly or when i save it some where locally and then open it i am getting the following message " File is repaired ot damaged.Operation failed." Any idea about what can be done??? Its very urgent.Please suggest.
I am not convetin to string just reading and writng as bytes itself.
Thanks in advance,
Mani
