Re: problem: security using IDE's appletviewer

Yes. You can specify many .jar files in the ARCHIVE parameter of the
APPLET tag. Just separate them with commas.

The HTML above loads both the test1.jar and test2.jar and runs the class
test2. The code for test2.java is almost the same as test1.java.
import java.applet.*;
import java.awt.*;
public class test2 extends Applet {
Image image;
public void init() {
image = getImage(getClass().getResource("kittens.jpg"));
}
public void paint(Graphics g) {
g.setColor(Color.BLUE);
if (!g.drawImage(image,0,0,this))
g.drawString("Loading Image",10,20);
}
}

Hi Knute,
Sorry but I cannot put this away because I cannot understand
something.
You have the image in a ("kittens.jpg") in a jar that has the name
"KnutesTest1.jar" (I made that name up here for the discussion).
I am now going to run your "test2" and I use your program above that
is supposed to access "KnutesTest1.jar" to grab the image
"kittens.jpg".
Yet in "test2" there is no clue that I can see where it is find the
image
you referred in test2:
"image = getImage(getClass().getResource("kittens.jpg"));"
It can't grab resources that, I don't think, that
are not stated.
Can you please clarify?
TIA,
bH
The answer is in the HTML file. Note that both test1.jar and test2.jar
are listed in the ARCHIVE element of the APPLET tag. The browser or
appletviewer will load all .jar files listed there. All classes and
files in both .jar files are available to the applet. In the HTML above
I tell it to run the test2.class. Does that explain it for you?
