[iText-questions] Reading a PDF and preserving bookmarks

I am trying to read in a PDF file so that I can place a date stamp on all of the page. The problem I am having is with copying the bookmarks from the pdf file that is read in into the new pdf file. I am able to preserve remote bookmarks and page bookmarks but I am having trouble getting named destination bookmarks to work. Could you send me a code example that would show me how I can copy a named destination bookmark into the new pdf and get it to work.

I am currently trying to do this.....

HashMap map = reader.getNamedDestination ();

Set c = map.entrySet() ;

Iterator it = c.iterator();

while (it.hasNext())

{

Map.Entry entry = (Map.Entry)it.next();

PdfArray pdfArray = (PdfArray)entry.getValue();

ArrayList aList = pdfArray.getArrayList();

PdfIndirectReference o = (PdfIndirectReference)aList.get(0);

PdfDestination des = new PdfDestination(PdfDestination.FIT, -1, 10000, 0);

boolean boo = des.addPage(o);

if (boo)

{

System.out.println(cb.localDestination((String)entry.getKey(), des));

}

When I close the document I get an null pointer exception

ExceptionConverter: java.lang.NullPointerException
