Servlet Pdf File Download Example Business

Step 5 Now delete the default "index.jsp" file and create a new "index.html" file and provide the following code for it. Our example application consists of a single class: PDFServlet. The OutputStream is a iText is an open source pure Java class library for creating and manipulating PDF documents. Visit the iText web site and download the current release. It's safer to create the file in memory using a ByteArrayOutputStream and to tell the browser how many bytes it can expect in the content header: public class PdfServlet extends HttpServlet { protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { // Get the text that will be added to the PDF String text = request.getParameter("text"); if (text == null text.trim().length() == 0) { text = "You didn't enter any text."; } // step 1 Document document = new Document(); // step 2 ByteArrayOutputStream baos = new ByteArrayOutputStream(); PdfWriter.getInstance(document, baos); // step 3; // step 4 document.add(new Paragraph(String.format( "You have submitted the following text using the %s method:", request.getMethod()))); document.add(new Paragraph(text)); // step 5 document.close(); // setting some response headers response.setHeader("Expires", "0"); response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0"); response.setHeader("Pragma", "public"); // setting the content type response.setContentType("application/pdf"); // the contentlength response.setContentLength(baos.size()); // write ByteArrayOutputStream to the ServletOutputStream OutputStream os = response.getOutputStream(); baos.writeTo(os); os.flush(); os.close(); } catch(DocumentException e) { throw new IOException(e.getMessage()); } } } For the full source code, see PdfServlet. Close both the FileInputStream and OutputStream.

It's possible to have a servletW serve up PDF content by specifying the content type of the servlet response to be the 'application/pdf' MIME type via response.setContentType("application/pdf").
