Hi there,

it seems icedtea does not include the JPEGCodec or Java beans
implementations used by EvA2. If using the Sun SDK, which is available
for Gentoo, I think, is not an option, this can not be easily solved.
The JPEG encoding is of course not vital (and can easily be replaced by
other implementations), but changing the GUI Bean usage is not as easy.
If you can make suggestions on alternative Bean implementations, please
let us know.
However, it should still be possible to use the EvA2 API for
optimization without the GUI, since the core optimization classes do not
depend on Java beans. So you should still be able to run the API example
from the short documentation, for instance.

Best wishes,
