/* this is the servlet method which is saving pdf file, but the same if run from Main then it saves the "hello world.pdf"*/ 
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException {
      try { 
          PDDocument  document = new PDDocument();
             PDPage page = new PDPage();
             document.addPage( page ); 
             // Create a new font object selecting one of the PDF base fonts
             PDFont font = PDType1Font.HELVETICA_BOLD; 
             // Start a new content stream which will "hold" the to be created content
             PDPageContentStream contentStream = new PDPageContentStream(document, page); 
             // Define a text content stream using the selected font, moving the cursor and drawing the text "Hello World"
             contentStream.beginText();
             contentStream.setFont( font, 12 );
             contentStream.moveTextPositionByAmount( 100, 700 );
             contentStream.drawString( "Hello World1" );
             contentStream.endText(); 
             // Make sure that the content stream is closed:
             contentStream.close(); 
             // Save the results and ensure that the document is properly closed:
             document.save( "Hello World.pdf");

             document.close();

             response.setContentType("text/html"); 
          PrintWriter out = response.getWriter();   
              out.println("<iframe height=\"100%\"   width=\"100%\" src=\"http://eurecaproject.eu/files/4613/9886/3802/report3.pdf\" ></iframe>");


    } catch (Exception e) {
        // TODO Auto-generated catch block

        System.out.println(e);
    }   

}

回答1:

If you update to the latest version of PDFBox (2.0.0-SNAPSHOT), everything should be ok.

Here is the example code: Sorry I am little bit busy so I can't test your code right now, but I am sure this will help you. Just add few lines while call doGet() or doPost() just check once what I am using. I spent many hours to find this solution. It will definitely work. If it won't work, please let me know.

I hope that you have already downloaded the pdfbox jar, so then you can import classes by default.

//you can use servlet to create pdf

            //Create Page

            //Adding the page
            document.addPage(page);


           //Loading the page
           File file = new File("D:/akash/my_doc.pdf");

           contentStream.showText("CHIMERA TRANSPLANT RESEARCH FOUNDATION");
           contentStream.endText();

           //Saving the document
           document.save("D:/akash/my_doc.pdf");


           //Closing the document
            document.close();
