    Save pdf into database using seam itext

    Prajwal Boloor Newbie

      Hi All,


      I have been using seam itext to generate pdf files using itext jsf tags.
      Now I have to save the generated pdf file as a blob in database.


      how can i use the existing xhtml file with the jsf itext tags and store the generated pdf on the database.


      any help on this



      Thanks in advance

          This is possible. You need to render the faces page. More information here




                  private byte[] createPDF(String path) {
                          // String DATA_STORE =
                          // "org.jboss.seam.document.documentStore.dataStore";
                          EmptyFacesContext emptyFacesContext = new EmptyFacesContext();
                          // Context conversation = Contexts.getConversationContext();
                          byte[] bytes = null;
          
                          try {
                                  Renderer.instance().render(path + "/status/status_pdf.xh
          tml");
                                  DocumentStore doc = DocumentStore.instance();
          
                                  if (doc != null) {
                                          DocumentData data = doc.getDocumentData("1");
                                          ByteArrayDocumentData byteData = null;
                                          if (data instanceof ByteArrayDocumentData) {
                                                  byteData = (ByteArrayDocumentData) data;
                                          } else {
                                                  throw new Exception("Couldnt get the byt
          es from the pdf document, unkown class " + data.getClass().getName());
                                          }
                                          bytes = byteData.getData();
                                  }
          
                          } catch (Exception ex) {
                                  log.error("Error when trying to get the content of the p
          df in bytes with the message #0", ex.getMessage());
                                  ex.printStackTrace();
                          } finally {
                                  emptyFacesContext.restore();
                          }
          
                          return bytes;
                  }



          This is how we do it

            I've been trying to put this solution to work but has no luck so far as Render.instance().render(viewID) throws


            java.lang.IllegalArgumentException: resource doesn't exist: tempTagReceiptPdf.xhtml



            This PDF enabled xhtml file is available under
            WebContent/pages/transactions/tempTagReceiptPdf.xhtml


            and used various ways to pass this view id but did not help.


            Could you please tell me what I should pass view id for the above path. By the way the app name is EZPass


            Thanks in advance.
