Make a List from a DB varchar data - NetBeans + Derby

Question

my problems is that i dont know how to make a list (Jlist from NetBeans) with some data from my derby db

EX:

I have a form that saves the id,name,phone and email from a "client", and i want to show all the names from my previously registered clients in a list, the problem is that i need to convert the varchar data into a listmodel. How can i do that? I tried this, but didn't work:

    while (rs.next()){
        int id_col = rs.getInt("clientID");
        String name = rs.getString("clientName");

        client_listClients.setText(name);       
    }

It says that "couldn't find symbol" for .setText

EDIT using DefaultListModel

WORKING RESULT!

public void DoConnect( ) {

    DefaultListModel model = new DefaultListModel();
    client_listClients.setModel(model);

    try {
        String host = "jdbc:derby://localhost:1527/ANAIA_DB";
        String uName = "*****";    
        String uPass = "*****";
        con = DriverManager.getConnection(host, uName, uPass);

        stmt = con.createStatement();
        String sql = "SELECT * FROM APP.CLIENT";
        rs = stmt.executeQuery(sql);


        while (rs.next()){

            int id_col = rs.getInt("clientID");       
            String name = rs.getString("clientName");
            model.addElement(name);
        }
    } catch (SQLException err) {
        JOptionPane.showMessageDialog(main.this, err.getMessage());
    }
}

Thx aloooot @peeskillet

"It says that "couldant find symbol" for .setText"

JList has no method setText() . When in doubt, read the docs

Instead, you'll want to use a ListModel . If you don't want to create your own, you can use the provided DefaultListModel implementation. There you have the method addElement .

You first need to declare your your list with the model.

DefaultListModel model = new DefaultListModel();
JList client_listClients = new JList(model);

Then you can use the method addElement , which will automatically update the UI after all additions are made. No need to do anything with the list.

while (rs.next()){

    String name = rs.getString("clientName");
    model.addElement(name);

}
