Hello,
I am successfully doing this, sending objects between an applet and a
servlet. I think your problem is that you call connect() before writing to
the output stream. Try putting the connect after you finish writing to the
connections output stream. This seems somewhat counter intuitive but the
output is actually sent as part of the connection process.
Here's my working code:
URLConnection urlConnection = (new
URL(serverURLString)).openConnection();
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
urlConnection.setRequestProperty ("Content-Type",
"application/octet-stream");
urlConnection.setAllowUserInteraction(false);
urlConnection.setUseCaches(false);
ObjectOutputStream oos = new
ObjectOutputStream(urlConnection.getOutputStream());
oos.writeObject(request);
oos.close();
urlConnection.connect(); <------------ connect only after writing
complete!!
ObjectInputStream ois = new
ObjectInputStream(urlConnection.getInputStream());
Object replyObject = ois.readObject();
Hope this helps,
Rob Griffin
