getResourceAsStream() just gets you the image data in a stream as
opposed to the URL. That won't help you with your question.

Yes. You can specify many .jar files in the ARCHIVE parameter of the
APPLET tag. Just separate them with commas.
<html>
<head>
</head>
<body>
<applet archive="test1.jar,test2.jar" code="test2.class"
width="640" height="480">
</applet>
</body>
</html>
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.
im****t java.applet.*;
im****t 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);
}
}
