Hi All,

Viewing an image, this applet, which compiles and shows an
image in the browser page IE with no error.

The image is located >outside< of the program folder.

I am having the problem with the IDE's appletviewer that
will not allow a image file to be read. The error
message on the AppletViewer's message bar at run time is:

exception:java.security.AccessControlException:Access
denied(java.io.FilePermission \C:\JBsm.jpg
read)

That said, I have looked at Canadian Mind Products
> P words > policy

The instructions say to use:

grant {
permission java.security.AllPermission;
};

I have added these lines above but now there is an error at
compile time for this applet:
<identifier> expected (obviously after the word "grant")

Something is missing but I have no idea. I am using
jdk1.5.0_12 and jre1.5.0_12
and stored in that same folder is there jre1.6.0_03 and
jre1.6.0_05

Thanks in advance for your help.

Here is the applet code:

import java.awt.*;
import java.applet.Applet;
import java.awt.Image;

public class ImageApplet extends Applet
  {
  private Image ioStream;
  private String errorMessage = null;

  public void init() {
    try
      {
      //ioStream = getImage(getCodeBase(),
      // "image/JBsm.JPG" );
      //above line works with both the IE browser page
      // and applet viewer
      ioStream = getImage(getCodeBase(),
"file:/C:/JBsm.JPG" );
      //above line works with the Browser page but fails
      //using the applet viewer

      //Insure image is downloaded before showing it
      MediaTracker tracker = new MediaTracker( this );
      tracker.addImage( ioStream, 0 );
      tracker.waitForID( 0 );
      repaint();
      }
    catch (InterruptedException netProblem )
      {
      errorMessage = "Could not reach image";
      }
    }

  public void paint( Graphics display)
    {
    if ( errorMessage == null )
      display.drawImage( ioStream, 0, 0, this );
    else
      display.drawString( errorMessage, 10, 10 );
    }
  }
