[jboss-user] [JBoss Seam] - Re: Hypersonic Database Explorer no longer runs up.

[tony.herstell@gmail.com]

Thats what I thought..

Works fine if my Seam app is not in the deploy area.

I am using IceFaces... would that intercept anything?

humm...  

I am causing havok with some graphix engine in Java actually using some code that does some image re-scaling... (getting quite a few exceptions after my image is rescaled but ignored them as seemed to have no bad effects)

I will run up, but not execute, my .ear and if confirmed will find a Java 2D expert to check my image rescaling code out.

So... Probably my code...


  |     @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  |     private byte[] getRescaledImageAsBytes(String contentType , int width, ImageIcon icon) {
  | 		double ratio = (double) width / icon.getIconWidth();
  | 		int height = (int) (icon.getIconHeight() * ratio);
  | 
  | 		int imageType = "image/png".equals(contentType) ? BufferedImage.TYPE_INT_ARGB
  | 				: BufferedImage.TYPE_INT_RGB;
  | 		BufferedImage bImg = new BufferedImage(width, height, imageType);
  | 		Graphics2D g2d = bImg.createGraphics();
  | 		g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
  | 							 RenderingHints.VALUE_INTERPOLATION_BICUBIC);
  | 		g2d.drawImage(icon.getImage(), 0, 0, width, height, null);
  | 		g2d.dispose();
  | 
  | 		String formatName = "";
  | 		if ("image/png".equalsIgnoreCase(contentType))
  | 			formatName = "png";
  | 		else if ("image/jpeg".equalsIgnoreCase(contentType))
  | 			formatName = "jpeg";
  | 		else if ("image/jpg".equalsIgnoreCase(contentType))
  | 			formatName = "jpg";
  | 		else if ("image/gif".equalsIgnoreCase(contentType))
  | 			formatName = "gif";
  | 
  | 		ByteArrayOutputStream baos = null;
  | 		OutputStream out = null;
  | 		try {
  | 			baos = new ByteArrayOutputStream();
  | 			out = new BufferedOutputStream(baos);
  | 			try {
  | 				ImageIO.write(bImg, formatName, out);
  | 			} catch (IOException e) {
  | 				e.printStackTrace();
  | 			}
  |         } finally { // Try to release any resources.
  |         	try {
  |                 if (baos != null) {
  |                 	baos.close();
  |                 }
  |             } catch (IOException ignored) {}
  |             try {
  |                 if (out != null) {
  |                     out.close();
  |                 }
  |             } catch (IOException ignored) {}
  |         }
  | 		return baos.toByteArray();
  |     }
