HELP with jPanels

[maverik_vz]

Using netbeans I've created new JFrame object with JPanel inside. Now I want to add new Jpanel object and add it to a previous JPanel.
Something like this:

package p;
public class mainFrame extends javax.swing.JFrame {
     public mainFrame() {
         super("New Frame");
         JPanel panel1 = new JPanel();
         add(panel1);
         panel2 p2=new panel2();
         panel1.add(p2);
         pack();
}}

public class panel2 extends javax.swing.JPanel {
     public panel2() {
        jLabel2 = new javax.swing.JLabel();
        jLabel1 = new javax.swing.JLabel();
        add(jLabel1);add(jLabel2);
}}

public class Main  {

    public static void main(String[] args) {
           mainFrame M = new mainFrame();
           M.setVisible(true);
}}

Of course, the new panel2 won't show in the mainFrame...please help...

The problem is with your use of layout manager. You should read the Sun Swing tutorial on this subject which you can find here: Lesson: Laying Out Components Within a Container (The Java™ Tutorials > Creating a GUI with JFC/Swing)
