ends up being "application/x-www-form-urlencoded", which probably messes-up the server-side parameter parsing --
ie, the server might be trying to parse your serialized object as POSTed params.
I think you would have to do something like:

Our client app tries to send a serialized object to a servlet.
The code looks like this
// prepareConnection
URL url = new
URL("http://myserver/servlet/AddressServlet/insert?addrType=15&parentFolder=17");
URLConnection urlConnection = url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
urlConnection.setUseCaches(false);
urlConnection.connect();
// sending Object
OutputStream urlOutStream = urlConnection.getOutputStream();
ObjectOutputStream objOut = new ObjectOutputStream(urlOutStream);
AdressObject newAddress= getNewAddressObject();
objOut.writeObject(newAddress); // send request
// cleanup
objOut.close();
The client app connect to the servlet but at the servlet side the
parameters from the URL are missing. Only the url
"myserver/servlet/AddressServlet/insert" is transmitted but a
request.getParameter("parentFolder") or getQueryString() returns null.
If we omit sending the serialized object and do the following
// prepareConnection
URL url = new
URL("http://myserver/servlet/AddressServlet/insert?addrType=15&parentFolder=17");
URLConnection urlConnection = url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
urlConnection.setUseCaches(false);
urlConnection.connect();
Object obj=urlConnection.getContent()
// cleanup
objOut.close();
everything works fine.
Is it possible to transmit a serliazed object via an URLConnection and
transmit also the UrlQueryString (e.g. the parameters
addrType=15&parentFolder=17) ???
Any help is appreciated.
Thanks in advance, Martin Pfeifer
