Applet problem
Posted by Jay on October 22, 2001 at 7:34 PM
When I run this code with appletviewer, import java.awt.*;
import java.net.*;
import java.applet.*; /**
Trying to display an image in the applet.
*/
public class ImageApplet extends Applet
{
Image pic; public void init()
{
URL url=null;
try
{
url = new URL("http://www.google.com/images/logo.gif");
pic = getImage(url);
}
catch(Exception e){}
System.out.println(url);
}
public void paint(Graphics g)
{
g.drawImage(pic, 0, 0, this);
}
}
I get the following exception: Exception occurred during event dispatching:
java.lang.NullPointerException

at java.awt.EventDispatchThread.run(EventDispatchThread.java:85)
I think this is some sort of AccessControl Exception. But I do not know how to get around this. Any help is sincerely appreciated.
Thanks,
Jay.
P.S: I am using JDK1.3 on Win2000.
