[Geotools-gt2-users] Problem with EPSG jars, crs not found

[<ced...@ge...>]

Hello everyone,

I'm experiencing a weird behaviour for the EPSG database management in 
Geoserver. I've compiled gt trunk (2.4 snapshot) and Geoserver trunk 
today with a jdk 1.5.0_10.

I have a coverage that is defined to use the code EPSG:41001.
In Geoserver version 1.6alpha2 (the current trunk), when I define my 
coverage, the code EPSG:41001 is found in the "SRS List" menu. So the 
SRS request and the SRS response are defined with this value.
So I send a WCS request like this : 
http://localhost:8080/geoserver1-6/wcs?bbox=-19981848.60,-13817347.59,20037508.34,13817347.59&format=jpeg&service=wcs&version=1.0.0&request=GetCoverage&coverage=geom:OA_20050518_1&crs=EPSG:41001&width=720&height=499.

But I get this error (the full stack trace in the attachement of this 
mail, I translate in english here) :
org.vfny.geoserver.wcs.WcsException: 
org.opengis.referencing.NoSuchAuthorityCodeException: No "EPSG:41001" 
code for the authority "European Petroleum Survey Group" was found for 
an object like "CoordinateReferenceSystem".

I know that the EPSG code 41001 is in the jar 
"gt2-epsg-extension-2.4-SNAPSHOT.jar" and is not present in the 
epsg-hsql jar at the same version of Geotools.
So the question I want to ask is : Is Geoserver parsing the 
epsg-extension jar when the URL request is sent, as when I define my 
coverage ?

When I use epsg-wkt it works well ...
Cheers,
Cédric B.
