Trying send object in a network!!!

I've trying to develop a chat application.And trying to send an object through the network but the server is not receiving it..

Code:

---

  public Boolean sendMessage(Command cmd, String msg)
    {
        try {
           
            DataObject obj = new DataObject();
            obj.setCommand(cmd);
            obj.setMessage(msg);
            obj.setUserName(myName);
            out = new ObjectOutputStream(socket.getOutputStream());
            out.writeObject(obj);
            out.flush();
            System.out.println("Sending Message "+obj.getCommand());
            return true;
        } catch (Exception ex) {
            System.out.println("Error sending message " +cmd.name());
            errMsg = ex.getMessage();
            return false;
        }
    }

---

the data object's(server Side) code is

Code:

---

ublic class DataObject implements java.io.Serializable {
    private Command command;
    private String message;
    private int userID;
    private int toUserID=0;

    public DataObject() {
    }

    public DataObject(Command command, String message,int userID) {
        this.command = command;
        this.message = message;
        this.userID=userID;
    }

    public Command getCommand() {
        return command;
    }

    public void setCommand(Command command) {
        this.command = command;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
   
    public int getUserID() {
        return userID;
    }

    public void setUserID(int userID) {
        this.userID = userID;
    }
   
    public int getToUserID() {
        return toUserID;
    }

    public void setToUserID(int toUserID) {
        this.toUserID = toUserID;
    }

 
}

There is like difference in data object of client its something like this

Code:

---

public class DataObject implements java.io.Serializable {
    private Command command;
    private String message;
    private int userID;
    private int toUserID;
    public DataObject()
    {}

    public DataObject(Command command, String message,String userName) {
        this.command = command;
        this.message = message;
        this.userID=Integer.parseInt(userName);
    }

    public Command getCommand() {
        return command;
    }

    public void setCommand(Command command) {
        this.command = command;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getUserName() {
        return Integer.toString(userID);
    }

    public void setUserName(String userName) {
        this.userID = Integer.parseInt(userName);
    }

    public String getTouser() {
        return Integer.toString(toUserID);
    }

    public void setTouser(String touser) {
        this.toUserID = Integer.parseInt(touser);
    }

   
}

I've converted the int to string in userID and toUser is this might be the problem??
Plz help..

You cannot serialise one class and expect to deserialise it into another class.
Doesn't matter if the names are the same...they have to be the same class, and the same version, etc etc.

I'm surprised you're not getting an exception when it's attempting to deserialise it.

It receives the connection.. Connects to the socket. When i try to send object it doesn't receives. When i connect and type through Telnet it receives the object received message.
BTW i've recoded the server dataobject same to as client dataobject..

What do you mean by recoded?
Are they no referencing the exact same class?

Not it different.. in client i've converted the int value of user and to user to string.. And i've change the of user and touser to string..

You're going to have to give us a better idea what's actually happening.
Is this code doing anything?

Code:

---

            out = new ObjectOutputStream(socket.getOutputStream());
            out.writeObject(obj);
            out.flush();

There an object called DataObject it stores username, command(an another type of user which has sets of enum commands),message(what other side receives) when you called sendMessage() which is in client calls the method and set the username(Id in above case) , command, and message. then it send that dataobject through the socket the

Quote:

---

out = new ObjectOutputStream(socket.getOutputStream());
out.writeObject(obj);
out.flush()

the socket here is the socket of the server..which i predefined it..
