Applet security?

Question

Hello all,
I need some help about publishing my application as an applet from my PC. As an application my program works fine.
1) I have developed an application (which extends JApplet class). I am using some jar files (which have been written by other people) in my application too (by defining paths of those jar files with classpath).
2) What I did is I put all my class files and the jar files that I use into a new jar file
3) I created an html file (a.html) which takes my jar file and I used Java HTML Converter to convert it to a suitable format.
4) I used keytool -genkey to create my key and I signed my applet.
5) When I open the a.html file I see that my user interface appears. But there are some problems:
a) I can't see my images that should be on the buttons.
b) My application does not work.
What is wrong in my process? My HTML files and the jar file I created are all in my working directory.
Thanks for any help

Answer 1

(1) Did you put the images in the Jar along with your class files?
(2) What code are you using to create the image? In Applets you need to use Applet method getImage(), otherwise it will look for the images on the local machine, which will of course result in a security exception.
Image im = getImage(getCodebase, "imagename");
ImageIcon ic = new ImageIcon(im);
