First thanks for help.
Our application is sending objects to the servlets using the URLConnection.
The servlet then processes the request and sends the appropriate response
object.
here is the code for our uploadObject method
URL servletURL url = new URL(location);
URLConnection urlConnection = url .openConnection();
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);
urlConnection.setDefaultUseCaches(false);
urlConnection.setRequestProperty("Content-Type",
"application/octet-stream");
outputToServlet = new
ObjectOutputStream(urlConnection.getOutputStream());
// send object to servlet
outputToServlet.writeObject(objectToServer);
// read object from servlet
inputFromServlet = new ObjectInputStream(urlConnection.getInputStream());
// Exception occurs here
the servlet code is (the doGet method)
in = new ObjectInputStream(request.getInputStream());
Object objectFromClient = in.readObject();
Object resultObject = processReceivedObject(objectFromClient,
request, response);
if (resultObject != null) {
// Create output stream to write Object
out = new ObjectOutputStream(response.getOutputStream());
out.writeObject(resultObject);
}
if (in != null) {
in.close();
}
// Close the output stream
if (out != null) {
out.flush();
out.close();
}

First question, how are you sending Objects to the servlet? Are you
sure that immediately following the HTTP header is your object? Why don't
you read the bytes and print them out to see if, perhaps, there is an extra
space or new line character in what you are reading?
