Re: browse a file from my desktop

I believe the question still applies: Does UPLOAD_DIRECTORY exist and can whatever runs your server side code write to it? In the example, it's "d:\\uploaded\\". Is that a real directory on your system? If not, you'll never upload the file.

Try creating your upload file with java.io.File.createTempFile(String prefix, String suffix) or as a file you name in a directory you can write to, like java.io.tmpdir:

...

File uploadedFile = File.createTempFile("gwt", "foo");

item.write(uploadedFile);

resp.setStatus(HttpServletResponse.SC_CREATED);

resp.getWriter().print("The file was created successfully.");

resp.flushBuffer();

... 

Use your development environment's debugger to step through your servlet and see where the error is, or put some System.err.println()'s into your servlet and see where it's failing.
