Witam. Mam taki kod serwera:
@Override
public void run() {
try {
serverSocket = new ServerSocket(9998);
while (true) {
Socket socket = serverSocket.accept();
System.out.println("connected");
input = new ObjectInputStream(socket.getInputStream());
Message ping = (Message) input.readObject();
System.out.println(ping.getMessage());
}
} catch (IOException | ClassNotFoundException e) {
e.printStackTrace();
}
}
I klienta:
@Override
public void start(Stage primaryStage) throws Exception {
socket = new Socket("localhost", 9998);
System.out.println("connected");
output = new ObjectOutputStream(socket.getOutputStream());
output.writeObject(new Message(CONFIG, "ping"));
FXMLLoader loader = new FXMLLoader(this.getClass().getResource("/window/fxmls/window.fxml"));
loader.setController(this);
AnchorPane anchorPane = loader.load();
Scene scene = new Scene(anchorPane);
primaryStage.setScene(scene);
primaryStage.show();
}
Gdy odpalam serwer, a następnie klienta, dostaję błąd w kliencie:

Jak można to naprawić? Wcześniej mi działało przesyłanie klasy Message.
A i klasa Message (ta które jest przesyłana):
package logic.message;
public class Message {
private Header header;
private String message;
private String recipient;
private String author;
public Message(Header header, String message) {
this.header = header;
this.message = message;
}
public Message(Header header, String message, String author) {
this.header = header;
this.message = message;
this.author = author;
}
public Message(Header header, String message, String recipient, String author) {
this.header = header;
this.message = message;
this.recipient = recipient;
this.author = author;
}
public Header getHeader() {
return header;
}
public String getMessage() {
return message;
}
public String getRecipient() {
return recipient;
}
public String getAuthor() {
return author;
}
}
Z góry dzięki za pomoc ;)
