[appengine-java] Problem whit upload form multipart

2010-02-16 Thread NIko Judo 
Hola he probado el codigo siguiente para recibir un formulario
multipart en mi aplicacion :

Test folowing code

import org.apache.commons.fileupload.FileItemStream;
import org.apache.commons.fileupload.FileItemIterator;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

import java.io.InputStream;
import java.io.IOException;
import java.util.logging.Logger;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class FileUpload extends HttpServlet {
  private static final Logger log =
  Logger.getLogger(FileUpload.class.getName());


  public void doPost(HttpServletRequest req, HttpServletResponse res)
  throws ServletException, IOException {
try {
  ServletFileUpload upload = new ServletFileUpload();
  res.setContentType("text/plain");

  FileItemIterator iterator = upload.getItemIterator(req);
  while (iterator.hasNext()) {
FileItemStream item = iterator.next();
InputStream stream = item.openStream();

if (item.isFormField()) {
  log.warning("Got a form field: " + item.getFieldName());
} else {
  log.warning("Got an uploaded file: " + item.getFieldName() +
  ", name = " + item.getName());

  // You now have the filename (item.getName() and the
  // contents (which you can read from stream).  Here we just
  // print them back out to the servlet output stream, but you
  // will probably want to do something more interesting (for
  // example, wrap them in a Blob and commit them to the
  // datastore).
  int len;
  byte[] buffer = new byte[8192];
  while ((len = stream.read(buffer, 0, buffer.length)) != -1)
  {
res.getOutputStream().write(buffer, 0, len);
  }
}
  }
} catch (Exception ex) {
  throw new ServletException(ex);
}
  }


@Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {

}



}

el caso es que simpre me da un error cuando envio el formulario con

Do you have a different version of the jar in your lib directory to  
the one on your build path?
