Re: PdfReader.getInfo returns null for Keywords

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&lt;String, Object>> bookmarks = new
ArrayList<HashMap&lt;String, Object>>();
	        List<HashMap&lt;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, &quot;Bookmarks from:
&quot;+listOfPdfs.get(i)+&quot; are of size: &quot;+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 &lt; 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.
