Thanks for the reply. I am not using PdfStamper because I am loosing the
hyperlink hidden in the pages that I am adding on top of the original Pdf.
Here is the code merging both Pdfs.
public void concatenate(String firstFile, String secondFile, String output)
{
try {
// Step 1
Document document = new Document();
PdfReader reader;
PdfReader.unethicalreading = true;
// Step 2.
PdfCopy copy = new PdfCopy(document, new
FileOutputStream(output));
// Step 2.5 Copying Pdf Properties.
reader = new PdfReader(secondFile);
HashMap<String, String> map = reader.getInfo();
String title = map.get("Title");
String author = map.get("Author");
String subject = map.get("Subject");
String keywords = map.get("Keywords");
String creator = map.get("Creator");
if (title != null)
document.addTitle(title);
if (author != null)
document.addAuthor(author);
if (subject != null)
document.addSubject(subject);
if (keywords != null) {
document.addKeywords(map.get("Keywords"));
}
if (creator != null)
document.addCreator(creator+"/Forest Service");
else
document.addCreator("Forest Service");
// Step 3.
document.open();
// Step 4.
int n;
int page_offset = 0;
List<String> listOfPdfs = new ArrayList<String>();
listOfPdfs.add(firstFile); // Pdf
with Customed pages.
listOfPdfs.add(secondFile); //
Original Pdf.
// Create a list for the bookrmarks
ArrayList<HashMap<String, Object>> bookmarks = new
ArrayList<HashMap<String, Object>>();
List<HashMap<String, Object>> tmp;
// loop over the documents you want to concatenate
for (int i=0; i<listOfPdfs.size(); i++) {
reader = new PdfReader(listOfPdfs.get(i));
reader.consolidateNamedDestinations();
// merge the bookmarks
tmp = SimpleBookmark.getBookmark(reader);
if (tmp != null) {
LogUtil.debug(log, "Bookmarks from:
"+listOfPdfs.get(i)+" are of size: "+tmp.size());
SimpleBookmark.shiftPageNumbers(tmp,
page_offset, null);
bookmarks.addAll(tmp);
}
// add the pages
n = reader.getNumberOfPages();
page_offset += n;
for (int page = 0; page < n;) {
copy.addPage(copy.getImportedPage(reader, ++page));
}
copy.freeReader(reader);
reader.close();
}
// Add the merged bookmarks
if (bookmarks.size() > 0)
copy.setOutlines(bookmarks);
// Step 5.
document.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Thanks.
