Hello Andrea,
that was the reason why i was setting up my project as maven project recently.
But the strange thing is: maven didn't recognize epsg-hsql as necessary
dependency. Only when I put the dependency by hand in the pom file maven
downloaded the dependency:
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-epsg-hsql</artifactId>
<version>${geotools.version}</version>
</dependency>
But now it works fine for me too. Thanks for helping.
Cheers
Albrecht

Hi all,
a class which formerly worked well for me now throws an exception when moving
my project to geotools-api 9 snapshot:
org.opengis.referencing.crs.CoordinateReferenceSystem cors =
org.geotools.referencing.CRS.decode("EPSG:25832");
throws the exception:
org.opengis.referencing.NoSuchAuthorityCodeException: No authority was defined
for code "25832". Did you forget "AUTHORITY:NUMBER"?
Is it a bug? I found some bugtracking to geotiff reader when prompting the
message to the search engine.
If yes, does anyone know a proper workaround?
Just tried out against 9.x, the following:
import org.geotools.referencing.CRS;
public class Decode {
public static void main(String[] args) throws Exception {
System.out.println(CRS.decode("EPSG:25832"));
}
}
prints out:

GEOGCS["ETRS89",
DATUM["European Terrestrial Reference System 1989",
SPHEROID["GRS 1980", 6378137.0, 298.257222101, AUTHORITY["EPSG","7019"]],

Normally that error happens if:
* you don't have a EPSG database in your classpath (either epsg-hsql or
epsg-wtk, I've tried
with the former)
* you have two or more of them, eventually with different version numbers
(happens a lot
to people not using maven to manage dependencies)
Cheers
Andrea
