Try using application/x-java-serialized-object instead of
application/octet-stream.

Hello All,
I need some help in solving this problem and I appreciate any messages in
this regard.
I am using Applet Servlet communication by http in my project. I was able
to
send the data from the servlet to the JApplet, but when I try to send new
data from the applet to the servlet I am getting the following exception in
the java console of Netscape:
java.io.IOException: The document contained no data.
Try again later, or contact the server's administrator.

In the error_log file of Apache this is the error shown:
java.io.StreamCorruptedException: Caught EOFException while reading the
stream header

at java.lang.Thread.run(Thread.java:479)
I am using the following code to send the data to servlet:
String urlString = getDocumentBase().toString();
urlString = urlString.substring(0,urlString.lastIndexOf("/")+1)+
"servlet/"+servletName;
URL servletURL = new URL(urlString);
URLConnection servletConnection = servletURL.openConnection();
servletConnection.setDoInput(true);
servletConnection.setDoOutput(true);
servletConnection.setUseCaches(false);
servletConnection.setRequestProperty("Content-Type",
"application/octet-stream");
servletConnection.connect();
ObjectOutputStream outputStmToServlet =
new ObjectOutputStream(new
BufferedOutputStream(servletConnection.getOutputStream()));
outputStmToServlet.writeObject(objToBeSend);
outputStmToServlet.flush();
outputStmToServlet.close();
}
Thanks for your time.
TIA
Srini
