Exeptions mir dem jfilechooser

[rock]

Hi, wollte einen einfachen filechooser der nur string array macht wo alle absolute pfade der Dateien drin sind die man angeklickt hat. Und das klappt auch aber er wirft die ganze Zeit IndexOutOfBoundsException
Kann mir einer helfen?

package applets;

import java.io.File;
import javax.swing.JFileChooser;


public class uploadapp extends javax.swing.JApplet {
    int returnVal=1;
    JFileChooser fc=new JFileChooser();
    
    public void init() {
        try {
            java.awt.EventQueue.invokeAndWait(new Runnable() {
                public void run() {
                    initComponents();
                }
            });
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

[Verjigorm]

Applet -> Sandbox
Darf nicht auf lokale Ressourcen zugreifen

Muss dafür signiert werden!

So generell noch:
- Klassenname groß
- Variablennamen klein

 

[rock]

Dann müsste eine andere Exception ausgeworfen werden, die auch ausgeworfen wird wenn ich es von einem html file aus lade.
Und bei Eclipse und NetBeans kann ich normal Dateien hin und her switchen und auch mehrere Dateien auswählen die dann auch ausgegeben werden aber es wird ständig die "java.lang.IndexOutOfBoundsException" ausgeworfen sonst läufts normal

[Gast]

kann viellecht jemand erklären was damit gemeint ist?

In the BasicDirectoryModel class the SwingUtilities.invokeLater(...) method should be invoked from caller thread instead of COM-thread.

ich benutze kein SwingUtilities.invokeLater

mein Programm:

// create a file chooser dialog
JFileChooser file_chooser = new JFileChooser(appletPath + searchDirectory);
file_chooser.setMultiSelectionEnabled(false);
file_chooser.setDialogType(JFileChooser.OPEN_DIALOG);

// set filter to accept .rpy files
file_chooser.setFileFilter(new FileFilter() {
public boolean accept(File f) {
return f.isDirectory() || f.getName().toLowerCase().endsWith(".rpy");
}
public String getDescription() {
return "Rhapsody Project Files (*.rpy)";
}
});

// set filter to accept XML files
file_chooser.setFileFilter(new FileFilter() {
public boolean accept(File f) {
return f.isDirectory() || f.getName().toLowerCase().endsWith(".xml");
}
public String getDescription() {
return "Model Description Files (*.xml)";
}
});

int iReturn = file_chooser.showOpenDialog(null);

if (iReturn == JFileChooser.APPROVE_OPTION) {
loadModelDesriptionFile(file_chooser.getSelectedFile().getAbsolutePath());
}
