The import javax.swing.JOptionPane cannot be resolved

[foggy swallow]

For some reason, it can't resolve JOptionPane. Running Eclipse 2022-09. Anyone got any idea what might be going wrong here?

int response = JOptionPane.showConfirmDialog(null,responseMsg, "Confirmation de reservation", JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE);
``` Here's where I'm calling it

import javax.swing.AbstractListModel;
import javax.swing.DefaultComboBoxModel;
import javax.swing.GroupLayout;
import javax.swing.GroupLayout.Alignment;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JList;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.LayoutStyle.ComponentPlacement;
import javax.swing.SwingConstants;
import javax.swing.border.EmptyBorder;
import javax.swing.border.LineBorder;
import javax.swing.event.ListSelectionEvent;
import javax.swing.event.ListSelectionListener;

Here's all my imports, everything is working perfectly fine, except for JOptionPane

Huh, that's very strange

Doesnt work for me either

In java 8, works perfectly, upgrade to 17: breaks

[foggy swallow]

Yeah, same thing im facing

Really weird

But i need it in java 17 💀

Apparently, JOptionPane is deprecated starting from java 17

Starting from Java 17, the JOptionPane class has been marked as deprecated, which means that it is no longer recommended for use in new code. Instead, you should use alternative classes from the javax.swing package or other libraries.

@foggy swallow in your module-info.java, add requires java.desktop;

that fixed it for me

[foggy swallow]

public void handleValidateEvent() {
        //Display confirmation window using JOptionPane
}
``` I love university

It's already in there

module tpcommunpartieihmdonnee {
    requires java.desktop;
    requires com.github.lgooddatepicker;
}

[restive cairn]

you saved the file?

[foggy swallow]

It's been in there since the start

[restive cairn]

oh

You can try adding the Java 8 library into your project

that also might work

[foggy swallow]

I'll see if that helps

Thanks!
