Hi,

In my applet jar, I have added the images that I want to show on the toolbar. In the init() function of the applet, I create the button and set the image, however, in the Java Console of the browser I get the following error message :

ava.lang.ExceptionInInitializerError

Can anyone please help me out ?
What all I need to do in order to access the images that are in the applet jar.

Thanks

The image is in the applet jar file. correct? If so, you can't access it using the file.io package - you need to treat them as resources and access it through the classloader. Some hints on how to do this can be found here.
 
It is sorta covered in the JavaRanch Style Guide.
