Thanks Martin, I tried to construct CRS with this WKT but it raises the
following exception:
Exception in thread "main" org.opengis.referencing.NoSuchIdentifierException:
Aucune transformation de classe "Lambert Azimuthal Equal Area" n'est définie.
at
org.geotools.referencing.operation.DefaultMathTransformFactory.getProvider(DefaultMathTransformFactory.java:266)
I'm using gt-2.3.1, not 2.3.2, and I have the following libs in my classpath
(among others):
gt2-referencing-2.3.1.jar
gt2-epsg-hsql-2.3.1.jar
gt2-epsg-wkt-2.3.1.jar

I confirm that CRS.decode("EPSG:3035") work with Geotools 2.4. But if you
prefer to stay with Geotools 2.3, an alternative is to use:
CRS.parseWKT(crsDefinition);
where 'crsDefinition' is the following string:
PROJCS["ETRS89 / ETRS-LAEA",
GEOGCS["ETRS89",
DATUM["European Terrestrial Reference System 1989",
SPHEROID["GRS 1980", 6378137.0, 298.257222101, AUTHORITY["EPSG","7019"]],
TOWGS84[0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0],
AUTHORITY["EPSG","6258"]],
PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]],
UNIT["degree", 0.017453292519943295],
