Passing info over a socket

Question

lets say I read in a vector from a file on a server, and I want to read the vector into another vector on the client side. I know the clients objectinputstream is the servers objectoutputstream, but how to I send objects over a socket connection.
Thanks.

Answer 1

client:
public class Client implements Serializable
Socket socket;
// PrintWriter out;
Vector userPass, guestBooks;
BufferedReader inp;
public Client()
try
socket = new Socket("13", 60);
// out = new PrintWriter(socket.getOutputStream(), true);
        ObjectInputStream in = new ObjectInputStream(socket.getInputStream());
        Object o1 = in.read();
        Object o2 = in.read();
        in.close();
catch(IOException e)
e.printStackTrace();
Server:
public class Server implements Serializable
ServerSocket sock;
Socket clnt;
File file1, file2, file3;
FileInputStream fis1, fis2, fis3;
Vector userspass, guestbooks;
public Server()
try
sock = new ServerSocket(60);
System.out.println("Listening on: Port 60");
clnt = sock.accept();
file1 = new File("user.txt");
file2 = new File("guestb.txt");
fis1 = new FileInputStream(file1);
fis2 = new FileInputStream(file2);
ObjectInputStream in1 = new ObjectInputStream(fis1);
ObjectInputStream in2 = new ObjectInputStream(fis2);
userspass = new Vector();
guestbooks = new Vector();
try //read in the object from the file to the vectors
while(in1.readObject()!= null)
userspass.add(in1.readObject());
while(in2.readObject()!= null)
guestbooks.add(in2.readObject());
          // here you want to send the vectors to the client?
          ObjectOutputStream out = new ObjectOutputStream(clnt.getOutputStream());
          out.write(userspass);
          out.write(guestbooks);
          out.close();
catch(Exception ex)
ex.printStackTrace();
sock.close();
sock.close();
catch(IOException e)
e.printStackTrace();
}Something like that. I have never used Object streams myself, so there's probably more to it (like making sure that vectors are serializable, and/or the contents in them). Also I'm not sure if closing the Object stream will close the socket's I/O stream also.... something for you to test and see.
