I keep my images in a jarfile and load them as followes:

Image image = null;
try
{
image = Toolkit.getDefaultToolkit().getImage( url );
}
catch ( Exception e )
{
// inform user.
}

This works fine, but when i accidently misspell the image name I get:

java.lang.IllegalStateException: zip file closed

at java.util.zip.ZipFile.getEntry(Unknown Source)

Why isn't the exception caught?

Because the operation is not executed on the same thread, and therefore the exception isn't, either. AFAIK, this is to prevent clogging up the EDT.

If you wish to load images in the same thread, consider using ClassLoader or the javax.imageio package.

Hi Vinoth!

thnx for spending your time to me...

I noticed later that class ImageIcon indeed waits for that thread to finish using MediaTracker.

But shouldn't method getImage() not FIRST check the presence of the image BEFORE starting the thread to load it? And the problem does not only occur with images, any file in the jar has the same problem.

And why is there no problem when the URL is referring to an image folder at the host? The unknown image simply isn't loaded then, but the program continues normally.
