Sorry for double-posting, I'm attaching some of the code I'm using:
I havent't mentioned other static styling images are rendering correctly.
byte[] imageByteArray = generateBarCodeImage(...)
> ByteArrayResource resource = new ByteArrayResource("image/jpeg",
> imageByteArray);
> Image barcodeImage= new Image("barcode", resource){
> protected void onComponentTag(ComponentTag tag)
> {
> super.onComponentTag(tag);
> String url = tag.getAttributes().getString("src");
> url = url + ((url.indexOf("?") >= 0) ? "&" : "?");
> url = url + "wicket:antiCache=" +
> System.currentTimeMillis();
> tag.put("src", url);
> }
> };
> barcodeImage.setMarkupId("barcodeImageId");
> barcodeImage.setOutputMarkupId(true);
> add(imatgeCodiBarres);
> .....
> link = new Link("printPDF"){
> private static final long serialVersionUID = 1L;
> @Override
> public void onClick() {
> try{
> String baseUrl = "http://myapp/";;
> // Get the html to render into pdf
> String html = RenderHTMLUtils.renderPage(new
> PrintPage(...));
> DocumentBuilder builder =
> DocumentBuilderFactory.newInstance().newDocumentBuilder();
> Document doc = builder.parse(new
> ByteArrayInputStream(html.getBytes("UTF-8")));
>
>
> String src =
> doc.getElementById("barcodeImageId").getAttribute("src");
> src = baseUrl + src;
>
> doc.getElementById("barcodeImageId").setAttribute("src", src);
>
> ITextRenderer renderer = new ITextRenderer();
> renderer.setDocument(doc, baseUrl);
>
>
> RequestCycle.get().setRequestTarget(EmptyRequestTarget.getInstance());
> WebResponse response = (WebResponse)
> getResponse();
> response.setContentType("application/pdf");
> response.setAttachmentHeader("printout.pdf");
> response.setHeader("Cache-Control",
> "max-age=0");
> OutputStream out = response.getOutputStream();
