Error as described here,

http://www.java.com/en/download/help/redximage.xml


most or nearly all applets from other pages display well in browser

this applet works with the appletviewer.


I got no help on the IRC channel  irc.freenode.net  #java  as they have
the policy  no applets.


I type this in a file

im****t javax.swing.*;

public class PreviewApplet2 extends JApplet
{

    static final long serialVersionUID = -3850477712741615045L;

    public void init()
    {
        JLabel niceLabel = new JLabel("Java is fun!");
        ImageIcon dukeIcon = new ImageIcon("duke_waving.gif");
        niceLabel.setIcon(dukeIcon);
        getContentPane().add(niceLabel);
    }
}


and compiles to a class


 javac  -Xlint  PreviewApplet2.java


I have the examples from here

http://www-cse.ucsd.edu/users/savitch/
 # my book is not listed,

Java:An Introduction to Computer Science and Programming, 2nd Edition

some other examples runs fine, from the command line, on windows
in the appletviewer and in the browser.

But this one gets
Red X image displayed where the applet should be, applets won't run



I use  appletviewer PreviewApplet2.html

and that works  fine.

permissions for the image is

-rwxrwxrwx    duke_waving.gif

a change in permissions to

-rw-r--r--   did not help.


on the  Tools Java  console I can se

in the error console I can see the above msg.

I did google for
java.io.FilePermission   duke_waving.gif

and found this explanation



How are you running the applet from the command line? In a browser? In
the appletviewer? Or as an application?

Security settings are different for all three. When applets run in a web
browser, access to the file system is, by default, not permitted. That
is normal.


End of explanation

I look it up from sun

http://java.sun.com/docs/books/tutorial/uiswing/components/icon.html#applet


Loading Images Into Applets

    Applets generally load image data from the computer that served up
the applet.


For me it looks like a contradiction.

If I include this line of code in the java file

  ImageIcon dukeIcon = new ImageIcon("duke_waving.gif");
        niceLabel.setIcon(dukeIcon);

I do expect java to do so and not additionally
append an <IMG SRC="filewithpicture.gif">   to the HTML code.


best regards

Morten
