Hi Mark,

I would guess that that's an internal Sun class not distributed with every JDK version. Googling for JPEGImageDecoderImpl shows a few hits, mostly on Linux JDKs.

Are you running your JVM in headless mode? Otherwise AWT won't work.

Start your JVM with -Djava.*awt*.*headless*=true, and it should work.

Hi,

When I try to use the ImageReader, I get

java.lang.NoClassDefFoundError
at sun.awt.image.codec.JPEGImageDecoderImpl.getDecodedColorModel(JPEGImageD ecoderImpl.java:293)


I'm running under OS X... the application runs fine on my PowerBook, but when I try to run it on the server I get this error. It's JDK 1.4.2 on my lappy, 1.4.1 on the server.

Any ideas?

Thanks,
Mark
