I am trying to display a JPEG image and a moving dot on a Java applet which I am using on a web based application. However, when I run the applet it works fine, but when I display the applet from the JSP page, I get the moving dot but not the JPEG image.
Is there a specific folder where the JPEG needs to be?
These are the 2 methods i use for drawing the
picture and the moving dot on the screen.
public class mapplet extends Applet implements Runnable {
int x_pos = 10;
int y_pos = 100;
int radius = 20;
Image img, img2;
Graphics gr;
URL base;
MediaTracker m;
@Override
public void init() {
mt = new MediaTracker(this);
try {
//getDocumentbase gets the applet path.
base = getCodeBase();
img = getImage(base, "
picture.jpg");
m.addImage(img, 1);
m.waitForAll();
} catch (InterruptedException ex) {
Logger.getLogger(movement.class.getName()).log(Level.SEVERE, null, ex);
}
public void paint (Graphics g) {
g.drawImage(img, 0, 0, this);
// set color
g.setColor (Color.red);
// paint a filled colored circle
g.fillOval (x_pos - radius, y_pos - radius, 2 * radius, 2 * radius);
}
The code one below is the call from the jsp page
<applet archive="mapplet.jar" code="myapplets/mapplet.class" width=350 height=200>
</applet>
The jar file and the
picture are in the same folder as the jsp page, and there is also a folder containing the contents of the class and image of the applet in the web section of the application. The applet loads fine however the
picture doesn't display. I think it's not the code but the location of the
picture that is causing a problem.
Thanks
