Am I Using ListSelectionListener Right?

Question

It keeps saying "Cannot resolve symbol: symbol class ListSelectionListener". I am doing this just like the examples I've seen, and I've included event package.... Am I doing the syntax wrong?
import java.awt.event.*;
import java.awt.*;     
import javax.swing.*;
public class InsFrame extends JInternalFrame
    static final int xOffset = 40, yOffset = 40;   
    private JList nameList;
    private String stNames[];
public InsFrame() {       
     super(" Insert New Grades ",
              true, //resizable
              true, //closable
              true, //maximizable
              true);//iconifiable
        //...Create the GUI and put it in the window...
        //...Then set the window size or call pack...
        setSize(300,300);        //Set the window's location.
        setLocation(xOffset, yOffset);
        Container content = getContentPane();
        setBackground(Color.white);
        content.setBackground(Color.white);
        content.setLayout(new FlowLayout());       
        stNames = Recieve.sendNames();             
        nameList = new JList (stNames);
        nameList.setVisibleRowCount( 6 );
        nameList.setSelectionMode(
          ListSelectionModel.SINGLE_INTERVAL_SELECTION );
        content.add( new JScrollPane( nameList ) );
        nameList.addListSelectionListener(
            new ListSelectionListener()     // <<< Cannot resolve symbol here
        { //Open Selection Listener
                public void valueChanged( ListSelectionEvent e)
                    // Do stuff here
        } // Close Selection Listener
        ); // End addListSelectionListener

add this to your imports
import javax.swing.event.*;
