Witam,
Mój problem jest następujący:
Mam funkcję, która zwraca ArrayListe obiektów typu jTable, których klasa wygląda tak:
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import java.util.ArrayList;
import javax.swing.ImageIcon;
public class jTable extends javax.swing.JFrame {
int TableSize;
int TableID;
int PlayerCount = 0;
int Seats = 0;
Image tlo;
String TableName;
Player [] PlayersOnTableList = new Player[100];
public jTable(int TableID) {
this.TableID = TableID;
this.setVisible(true);
setPreferredSize(new Dimension(794,547));
initComponents();
setTitle("JavPox - tableID: "+TableID);
tlo = new ImageIcon(this.getClass().getResource("table.jpg")).getImage();
repaint();
}
public void AddPlayer(int PlayerID){
System.out.println("PlayerID = " + PlayerID);
switch(Seats){
case 0: this.label1.setText(PlayersOnTableList[PlayerID].Nick); Seats++; break;
case 1: this.label2.setText(PlayersOnTableList[PlayerID].Nick); Seats++; break;
case 2: this.label3.setText(PlayersOnTableList[PlayerID].Nick); Seats++; break;
case 3: this.label4.setText(PlayersOnTableList[PlayerID].Nick); Seats++; break;
case 4: this.label5.setText(PlayersOnTableList[PlayerID].Nick); Seats++; break;
case 5: this.label6.setText(PlayersOnTableList[PlayerID].Nick); Seats++; break;
case 6: break;
}
}
public void paint(Graphics g)
{
Graphics2D g2 = (Graphics2D)g;
g2.drawImage(tlo,0, 0, null);
repaint();
}
@SuppressWarnings("unchecked")
private void initComponents() {
label1 = new java.awt.Label();
label2 = new java.awt.Label();
label3 = new java.awt.Label();
label4 = new java.awt.Label();
label5 = new java.awt.Label();
label6 = new java.awt.Label();
label7 = new java.awt.Label();
label8 = new java.awt.Label();
label9 = new java.awt.Label();
label10 = new java.awt.Label();
setDefaultCloseOperation(javax.swing.WindowConstants.DISPOSE_ON_CLOSE);
setResizable(false);
getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());
label1.setAlignment(java.awt.Label.CENTER);
label1.setText("Empty Seat");
getContentPane().add(label1, new org.netbeans.lib.awtextra.AbsoluteConstraints(380, 390, -1, -1));
label2.setAlignment(java.awt.Label.CENTER);
label2.setText("Empty Seat");
getContentPane().add(label2, new org.netbeans.lib.awtextra.AbsoluteConstraints(46, 302, -1, -1));
label3.setAlignment(java.awt.Label.CENTER);
label3.setText("Empty Seat");
getContentPane().add(label3, new org.netbeans.lib.awtextra.AbsoluteConstraints(46, 106, -1, -1));
label4.setAlignment(java.awt.Label.CENTER);
label4.setText("Empty Seat");
getContentPane().add(label4, new org.netbeans.lib.awtextra.AbsoluteConstraints(380, 50, -1, -1));
label5.setAlignment(java.awt.Label.CENTER);
label5.setText("Empty Seat");
getContentPane().add(label5, new org.netbeans.lib.awtextra.AbsoluteConstraints(690, 110, -1, -1));
label6.setAlignment(java.awt.Label.CENTER);
label6.setText("Empty Seat");
getContentPane().add(label6, new org.netbeans.lib.awtextra.AbsoluteConstraints(690, 300, -1, -1));
label7.setAlignment(java.awt.Label.CENTER);
label7.setText("Empty Seat");
getContentPane().add(label7, new org.netbeans.lib.awtextra.AbsoluteConstraints(190, 390, -1, -1));
label8.setAlignment(java.awt.Label.CENTER);
label8.setText("Empty Seat");
getContentPane().add(label8, new org.netbeans.lib.awtextra.AbsoluteConstraints(190, 50, -1, -1));
label9.setAlignment(java.awt.Label.CENTER);
label9.setText("Empty Seat");
getContentPane().add(label9, new org.netbeans.lib.awtextra.AbsoluteConstraints(570, 50, -1, -1));
label10.setAlignment(java.awt.Label.CENTER);
label10.setText("Empty Seat");
getContentPane().add(label10, new org.netbeans.lib.awtextra.AbsoluteConstraints(560, 390, -1, -1));
pack();
}
private java.awt.Label label1;
private java.awt.Label label10;
private java.awt.Label label2;
private java.awt.Label label3;
private java.awt.Label label4;
private java.awt.Label label5;
private java.awt.Label label6;
private java.awt.Label label7;
private java.awt.Label label8;
private java.awt.Label label9;
}
Funkcja na serwerze wygląda następująco:
public ArrayList RefreshTableList() throws RemoteException {
return TableList;
}
Przy czym TableList to ArrayLista obiektów typu jTable.
Funkcja, która wywołuje zdalnie powyższą metodę:
public void RefreshTableList(){
ArrayList<jTable> TableListToList = new ArrayList<jTable>();
try{
PokerInterface Server = (PokerInterface)Naming.lookup("Server");
TableListToList = Server.RefreshTableList();
} catch (NotBoundException ex) {
Logger.getLogger(MainLobby.class.getName()).log(Level.SEVERE, null, ex);
} catch (MalformedURLException ex) {
Logger.getLogger(MainLobby.class.getName()).log(Level.SEVERE, null, ex);
} catch (RemoteException ex) {
Logger.getLogger(MainLobby.class.getName()).log(Level.SEVERE, null, ex);
}
}
Jeśli TableList jest pusty, funkcja działa, tj. zwraca faktycznie pusty ArrayTable. Jeśli jednak znajdują się w niej jakieś elementy, otrzymuję wyjątek:

Dodam, że mam drugą funkcję, zwracająca ArrayTable Stringów, i ona działa poprawnie.
Z góry dziękuję za jakiekolwiek wskazówki.
