Re: Help to upgrade code from FOP 1.1 to FOP 2.2

Hello,

My code looks like this...

public static synchronized DocResult generateImpl(String outputFormat,
Document document, Node dataNode, String pageCount) {
   log.debug("generateImpl: start");

   if (dataNode == null) {
      return null;
   }

   DocResult docResult = null;

   Source xslfo = generateXslFo(document);

   try {
      // configure fopFactory as desired with the needed resolvers
      ResourceResolver defaultResolver =
ResourceResolverFactory.createDefaultResourceResolver();
      SchemeAwareResourceResolverBuilder resolverBuilder =
ResourceResolverFactory.createSchemeAwareResourceResolverBuilder(defaultResolver);
      resolverBuilder.registerResourceResolverForScheme("image", new
ImageResolver());
      resolverBuilder.registerResourceResolverForScheme("measurementImage",
new MeasurementImageResolver());
      ResourceResolver resolver = resolverBuilder.build();
      FopFactory fopFactory = new FopFactoryBuilder(new
File(".").toURI(), resolver).build();

      FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

      if(MIME_TIFF.equalsIgnoreCase(outputFormat)) {
            // Give TIFF a high compression ratio
            TIFFRenderer renderer = new TIFFRenderer(foUserAgent);
            BitmapRenderingSettings renderingSettings =
renderer.getRenderingSettings();
            renderingSettings.setCompressionMethod("LZW"); // LZW,
JPEG, PACKBITS
            foUserAgent.setRendererOverride(renderer);
      }

      // configure foUserAgent as desired
      foUserAgent.setTargetResolution(document.getPreviewDPI()); //
only used for bitmap targets and not for PDF targets

      ByteArrayOutputStream out = new ByteArrayOutputStream();

      // Construct fop with desired output format
      Fop fop = fopFactory.newFop(outputFormat, foUserAgent, out);

      // Setup XSLT
      TransformerFactory factory = TransformerFactory.newInstance();
      factory.setErrorListener(new TransformerErrorListener());
      Transformer transformer = factory.newTransformer(xslfo);
      if (transformer == null) return null;
      transformer.setErrorListener(new TransformerErrorListener()); //
log transformer errors / warnings to our log4j logger
      transformer.setParameter("versionParam", "2.0"); // Set the
value of a <param> in the stylesheet
      LocalDateTime now = DateTimeHelper.getNow();
      transformer.setParameter("currentDate",
DateTimeHelper.localDateTimeToString(Format.DATE_FORMAT_2, now));
      transformer.setParameter("currentTime",
DateTimeHelper.localDateTimeToString(Format.TIME_FORMAT_1, now));
      transformer.setParameter("pageCount", pageCount);

      // Use size and margins from the template or from the document?
      Document templateDocument = document.getTemplateDocument();
      Document masterDocument = document;
      if (templateDocument != null) {
         masterDocument = templateDocument;
      }

      transformer.setParameter("pageHeight", masterDocument.getHeight());
      transformer.setParameter("pageWidth", masterDocument.getWidth());
      transformer.setParameter("margin-top", masterDocument.getMarginTop());
      transformer.setParameter("margin-bottom",
masterDocument.getMarginBottom());
      transformer.setParameter("margin-left", masterDocument.getMarginLeft());
      transformer.setParameter("margin-right", masterDocument.getMarginRight());

      // Setup input for XSLT transformation (FOP needs SAX!)
      String dataString = XMLUtils.w3cNodeToString(dataNode);

      SAXBuilder saxBuilder = new SAXBuilder();
      saxBuilder.setErrorHandler(new SaxParserErrorListener());
      org.jdom2.Document dataDocument = saxBuilder.build(new
StringReader(dataString));
      DOMSource src = new DOMSource((new DOMOutputter()).output(dataDocument));

      // Resulting SAX events (the generated FO) must be piped through to FOP
      Result res = new SAXResult(fop.getDefaultHandler());

      // Start XSLT transformation and FOP processing
      transformer.transform(src, res);
      docResult = new DocResult();
      docResult.setFop(fop);

      docResult.setData(out.toByteArray());
   } catch (Exception e) {
      log.error("Problem generating PDF file (probably an error in one
of the XML strings)", e);
      return null;
   }

   log.debug("generateImpl: end");
   return docResult;
}


Not directly useable but might help.

MAG,
Milo
