Hi Martin and Jody,
I'm now using your suggestion to make the transformation, but this operatio in
too slow.
This is my source code:
CoordinateOperationFactory coFactory =
FactoryFinder.getCoordinateOperationFactory(null);
CoordinateOperation co = coFactory.createOperation(CRS.decode("EPSG:4326"),
CRS.decode("EPSG:3003"));
MathTransform trans = co.getMathTransform();
Whatching the debug console I've seen two error messages:
1 - Bursa Wolf Parameter Required
2 -
AVVERTENZA: Can't load a service for category DataSource.

In my application's classpath there's the gt2-epsg-wkt.
There's some method to make the transformation quick.

Hi Martin:
I slurped up your reply onto this page:
- http://docs.codehaus.org/display/GEOTDOC/01+Helper+Classes
Going to try and capture at least examples by trolling the user list.
