Cocoon error when generating graphics in PDFs

[Stephan Kassanke <ka...@gmx.de>]

Hi all,

I would like to include graphics in PDF documents rendered by Cocoon. The
problem we have is, that it simply does not work. Cocoon throws an exception
about a method not defined in the AWT. We are running Cocoon 1.8.2 and JVM
1.1.8. The stylesheets are checked and validated by a manual FOP conversion,
we are using full classified URLs, so can't be the reason neither. i read
about X-references recently. is that a clue?

Thanks,
Stephan

The error is
      Cocoon 1.8.2




      Error found handling the request.
java.lang.NoSuchMethodError: java.awt.image.ColorModel: method hasAlpha()Z
