URLClassLoader loader = new URLClassLoader(new URL[] { file.toURL() }); Class clazz = loader.loadClass("Main"); Applet applet = (Applet) clazz.newInstance();

If I load a class that way, is it possible to replace (override) methods in the created object?

int width = (int) getPreferredSize().getWidth(); //... boxes[i][j].setBounds(width + boxSize * j,height + boxSize * i ,boxSize, boxSize);

Looks like you're putting the boxes too much to the right.

The methods should be inside the class.

public class converter { JPanel mainPane; } //End of class

You can define a custom pattern in SimpleDateFormat. It inherits a method String format(Date date)

There are detailed instructions for many routers at http://www.portforward.com/routers.htm how to forward a port.

component.setBorder(BorderFactory.createLineBorder(Color.BLACK, 6));

Can you use that?

Override JPanel's paintComponent(Graphics g) method:

protected void paintComponent(Graphics g1) { Graphics2D g = (Graphics2D) g1; super.paintComponent(g); g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, alpha)); g.drawImage(image1, 0, 0, null); g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 1.0f - alpha)); g.drawImage(image2, 0, 0, null); }

Then use a thread to increase or decrease the alpha value.

JApplet's content pane is painted on the JApplet. http://java.sun.com/docs/books/tutorial/uiswing/14painting/index.html

I have a server application and a client applet and I want to know what the best way to communicate between them is. I have thought of two possibilities.
The first one is a text-based protocol where messages are sent by using DataOutputStream.writeUTF(String str).
In the other a code (byte) describing the message is sent first, and then data in various formats (byte, long, String). Less data (in bytes) would be needed to sent but the problem is that if the receiver didn't read the right number of bytes, the next messages would be screwed up.
Which method would you recommend or is there an article I should read?

Edit: It is a multiplayer game. If a player's status changes (which happens often), the new status needs to be sent to other players.

myFrame.setAlwaysOnTop(true);

Inherited from Window.

Or JComponent. Canvas is a heavy-weight (AWT) component and the classes which start with J are light-weight components (Swing). You shouldn't usually mix AWT and Swing in your program because it can cause problems like the one you experienced.

The JPanel will be added with the JScrollPane.

Here's an example:

JFrame frame = new JFrame(); JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.PAGE_AXIS)); for(int i = 0; i < 20; i++) { panel.add(new JButton("Button " + i)); } frame.add(new JScrollPane(panel)); frame.setSize(200,200); frame.setVisible(true);

Put static modifier back to the main-method. What kind of compilation errors did it give when you removed the statics?

You add a component to a JScrollPane, not vice versa. Make sure it is m_scrollpane you added to the container (JFrame) and not m_itempanel.
