ok, i've found IBM reference implementation and got some questions:
media is added using:
| MediaEntityLocal imgSamp = mediaEntityHome.create();
| imgSamp.setName("image"+System.currentTimeMillis());
imgSamp.setContent(getServletContext().getResourceAsStream("/samples/image1.jpg"));
| imgSamp.setDescription("kocio");
| imgSamp.setMimeType("image/jpeg");
|
in database record is filled in, image content exists but when:
| MediaEntityLocal media = mediaEntityHome.findByPrimaryKey(imgId);
| resp.setContentType(media.getMimeType());
| resp.setContentLength((int) media.getSize());
|
| byte[] buffer = new byte[0x10000];
| long position = 0;
| int bytesRead = 0;
| while ((bytesRead = media.readContent(position, buffer)) != -1)
| {
| log("bytes read: " + bytesRead);
| resp.getOutputStream().write(buffer, 0, bytesRead);
| position += bytesRead;
| }
|
copied from emb spec, serwer throws this:
