passing Serialized objects to Servlets

  Asked By: Rani    Date: Sep 29    Category: Java    Views: 3643
  

I need to pass a serialiazed object and some parameters to my servlet. I
can pass a serialized object to my servlet, and I can pass parameters to
my servlet.
But when I try to pass both, I only get my serialized object. The other
parameter is null.
Here is the code used to pass these kind of parameters to my servlet


URL url = new
URL("http://192.168.61.77:8080/urlservlet/servlet/UrlServlet");
URLConnection connection;
connection = url.openConnection();

connection.setDoOutput(true);
// UrlSerializable is my class that implemenst Serializable
UrlSerializable urs = new UrlSerializable();
urs.setTestando("Servlet Recebendo = Objeto Serializ√°vel!!!");
// Serializing the object to the output stream that the conection
has.
OutputStream out1 = connection.getOutputStream();
ObjectOutputStream s = new ObjectOutputStream(out1);
s.writeObject(urs);

s.close();
s.flush();
// Passing paramters to the servlet. These parameters are
supossed to be fetch with the request.getParameter() method
PrintWriter outq = new PrintWriter(connection.getOutputStream());
outq.println("string=Param");
outq.close();
outq.flush();

My servlet code is:

public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
try
{
Unserializing the object
ObjectInputStream s = new ObjectInputStream(in1);
UrlInterface dados = (UrlInterface) s.readObject();
dados.checaVersao();

System.out.println("***** SERIALIZABLE ****");
System.out.println("Serialized Content: "+dados.getTestando());
// here my parameter string is null. And there is content in it.
System.out.println("Param :"+req.getParameter("string"));


Any ideas ?
