Re: [iText-questions] PdfReader.getInfo returns null for Keywords

[bhopB]

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();
