This means that the specific JPEG format you are trying is not supported. The JPEG decoder in Classpath is very incomplete and doesn't support the mainstream JPEG formats. Your options are: 1. try to use the OpenJDK JPEG decoder in Classpath somehow (should be possible because it is designed as a plugin for IIO) 2. try to implement the missing JPEG formats ;-) Roman -- http://kennke.org/blog/
