Simone, I am currently working with GeoTools 2.2.1 ... I've been sticking to it because it is advertised as "the stable release". It didn't even occur to me to investigate the later releases. I'll have to do so later on.
Again, this behavior isn't a bug so much as a feature. The documentation for the GeoTiffReader class specifically states that the read operation will throw an exception for an unimplemented projection as a way of documenting its existence... the code correctly realizes that it does not support the Lambert projection and informs the calling application of the condition. I believe that the problem-tracking database identifies GEOT-671 as a bug because the author felt that the unsupported projections were really common enough that addressing them needed to be a priority. I'll have a look at the more recent releases and see if they support the Lambert. And I'll also try to find you an example file on the web (since I can't send you mine). Gary --- Gary W.

In addition a sample file would be great in order to test on GeoTools 2.3.x. Thx a lot, Simone.
