Multiple Components in a JFrame (simple question)

Question

Hello everyone, I need to put two components in my JFrame, and I have been expieriencing some odd problems. I use this to add my components...
MyComponent mc=new MyComponent();
MyOtherComponent me = new MyOtherComponent();
When I try to access methods they work fine. I can use repaint() in a method and it works. BUT when I try to draw on the component using anything besides paintComponent() It gives me a java.lang.NullPointerException
here is what I tried.....
me.draw(getGraphics());
//later on in the component def..
draw(Graphics g) {
} // I get a java.lang.NullPointerException in main
whenever i use getGraphics() it does'nt work what am I doing wrong?

Answer 1

Yup I did that and repaint does jack all. When I run the code all I see the contents of the first component. I know that the methods of the second component are being executed, but the paintComponent method is simply not running. I put a System.out.println("hi"); in and it never showed in the console..
Anyone who can help me gets a duke, here's my second component code..
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
class MyOtherComponent extends JComponent {
public void paintComponent(Graphics gg) {
System.out.println("paintComponent executed!!!");
Graphics2D g2D = (Graphics2D)gg;
ImageIcon icon = null;
try {icon = new ImageIcon(new URL("http://images.neopets.com/m.gif")); }
catch(MalformedURLException e) {
System.out.println("no"); return;
resize(icon.getIconWidth(),icon.getIconHeight());
Image mark = icon.getImage();
g2D.drawImage(mark,0,0,this);
g2D.drawString("hello folk",40,40);
drawe(g2D);
public void drawe(Graphics2D g2D) {
g2D.drawLine(50,50,500,500);
g2D.fillRect(20,20,20,20);
repaint();
public void line() {
System.out.println("Hello, from MyOtherComponent");
public void re() {
repaint();
System.out.println("re");
