that can use the byte array or inputstream to show the image....
? You need to explain that.. Inject the hibernate provider into the
webresource and look up the blob?

You could also just inject the provider and serve it if not loaded, eg
the method above + injection, I think thats the best option, as it
should be cluster safe..
or this:
package zeuzgroup.application.utils;
import java.awt.image.BufferedImage;
import org.apache.wicket.markup.html.image.resource.DynamicImageResource;
public class ImageResource extends DynamicImageResource {
// has to save this. or get the image another way!
private byte[] image;
public ImageResource(byte[] image, String format) {
this.image = image;
setFormat(format);
}
public ImageResource(BufferedImage image) {
this.image = toImageData(image);
}
@Override
protected byte[] getImageData() {
if (image != null) {
return image;
} else {
return new byte[0];
}
}
/**
* 1 day!
*/
@Override
protected int getCacheDuration() {
return 3600*24;
}
}

hi, i want to upload a image from wicket and store it into dabase, how
can i

in hibernate, i define the type as Blob to store the image,
however, when i try to read it,
get the input stream from blob
it always complain that after serialzation, blog may not be asscessable.
/////
item.add(new Image("imgItem", new Resource() {
@Override
public IResourceStream getResourceStream() {
return new AbstractResourceStream() {
public InputStream getInputStream()
throws
ResourceStreamNotFoundException {
return
blob.getBinaryInputStream();
}
public void close() throws IOException {
// close input stream
}
};
}
}) );
////

Thanks.....
