Hi Felix,
I too tried to use the CRS class on the server side of a GWT application
running inside Jetty and wrote the list about it.
I also tried with epsg-wkt as Jody mentioned, but didn't succeed either.
I was using GeoTools to convert from UTM to WGS84, and vice-versa, from an
application which ran stand alone. When I had to migrate it to Jetty, it
would fail with the error you stated.
The solution for me was to drop GeoTools from the project and go with JCoord
and that worked really well.
Regards,
Alexandre Pretyman
