Java converting byte[] to image

I know this seems like a common question but i have looked all over the internets, and tried many different tutorials and methods for doing this. I think i am close, but not sure. Also i am using Play Framework but it should be the same for java. here is my error ``` javax.image.IIOException: I/O error reading PNG header! at com.sun.plugins.png.PNGImageReader.readHeader(Unknown Source) ... ... Caused by: java.io.EOFException at javax.imageio.stream.ImageInputStreamImpl.readFully(Unknown Source) ... ``` Here is my code where i get the picture among other things from a form and convert the image to a byte[] and store in MS SQL db. ``` @Transactional public static Result submitTrailer(){ filledForm = newTrailerForm.bindFromRequest(); MultipartFormData body = request().body().asMultipartFormData(); FilePart picture = body.getFile("file"); String fileName = picture.getFilename(); System.out.println(fileName); String contentType = picture.getContentType(); System.out.println(contentType); final File file = picture.getFile(); filledForm.get().setContentType(contentType); try{ BufferedImage originalImage = ImageIO.read(file); ByteArrayOutputStream baos = new ByteArrayOutputStream(); ImageIO.write(originalImage, contentType, baos); filledForm.get().setImage(baos.toByteArray()); baos.flush(); baos.close(); filledForm.get().save(); }catch(IOException e){ e.printStackTrace(); } return ok(views.html.index.index.render()); } ``` here is where i am trying to covert the byte[] back to an image so i can display it in html ``` public File getConvertedPicture(){ File imageFile; System.out.println("byteToImage() called"); if(getImage()==null){ System.out.println("getByteImage()==null"); return null; }else{ try{ ByteArrayInputStream bis = new ByteArrayInputStream(getImage()); imageFile=File.createTempFile("pattern", ".suffix"); Iterator<?> readers = ImageIO.getImageReadersByFormatName("PNG"); ImageReader reader = (ImageReader) readers.next(); Object source = bis; ImageInputStream iis = ImageIO.createImageInputStream(source); reader.setInput(iis, true); ImageReadParam param = reader.getDefaultReadParam(); Image image = reader.read(0, param); BufferedImage bufferedImage = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_RGB); Graphics2D g2 = bufferedImage.createGraphics(); g2.drawImage(image, null, null); ImageIO.write(bufferedImage,"PNG", imageFile); return imageFile; } catch(IOException e){ e.printStackTrace(); return null; } } ``` I am a beginner, this is my first time using play, and first time using databases. Any advice to get this to work would be greatly appreciated. also, in my method getConvertedPicture() i have to specify the format type, is there anyway to get around this so the user can upload any type of picture they want.
