Hi alexandrecoelho,
Here is a demo without any other configuration: http://www.zkoss.org/zkdemo/file_handling/file_upload
Can you show us your code and configuration?

Hi, thanks!!

The upload it´s working, but when i create a file with the uploaded media, the size of file is 0KB. That just happened with files less than 17KB.

The part of code is:

		Media media = ((UploadEvent)event).getMedia();

		String path = Executions.getCurrent().getDesktop().getWebApp().getRealPath("/arquivos") + "\\"; 

		try {
		
	          if (media.isBinary()) {
				File dest = new File(path + media.getName());
				Files.copy(dest, media.getStreamData());
			}
			else {
				BufferedWriter writer = new BufferedWriter(new FileWriter(path + media.getName()));
				Files.copy(writer, media.getReaderData());
			}

		} catch (IOException e) {
			e.printStackTrace();
		}

Hi,

you have to check if the media is present in memory when creating the appropriate input stream / reader. Here's an example:

InputStream stream = new BufferedInputStream(media.inMemory() ? new ByteArrayInputStream(media.getByteData()) : media.getStreamData());
...
Reader reader = new BufferedReader(media.inMemory() ? new StringReader(media.getStringData()) : media.getReaderData());

Cheers, Maik
