I have tried to Save the Content of the media to disk, but failed. I have tried to cast it to Object and save it but failed. Does anyone know how to save the content.
Just create a Java-Utiltity which handles the task for you:
import java.io.File;
import java.io.FileOutputStream;
import org.zkoss.zul.Fileupload;
public class Upload {
public static void saveToDisk() throws Exception {
org.zkoss.util.media.Media media = Fileupload.get();
FileOutputStream fos = new FileOutputStream(new File(media.getName()));
fos.write(media.getByteData());
fos.close();
}
}
So you can trigger a upload from ZUL via:
<button label="Upload" onClick="Upload.saveToDisk()" />

I have tried that, i get a message telling me that i must use getStreamData() instead.
How do i get the content from this method. I am using ZK 3.0.5.
Something like this should work directly with InputStreams:
public static void saveToDisk() throws Exception {
org.zkoss.util.media.Media media = Fileupload.get();
OutputStream outputStream = new FileOutputStream(new File(media.getName()));
InputStream inputStream = media.getStreamData();
byte[] buffer = new byte[1024];
for (int count; (count = inputStream.read(buffer)) != -1;) {
outputStream.write(buffer, 0, count);
}
outputStream.flush();
outputStream.close();
inputStream.close();
}
