Hi,i solved the problem without knowing the cause of the probleme.i started by 
downloading all the geotools in my project (11.2 version) and removing some of 
the jars as explained in the tutorial.i am sur i had the "gt-epsh-hsql.jar" in 
te project buildPath too.
in a second time i used maven command line to create java project and using it 
to download the required jars to my local repository, then used eclipse to 
import the project. that works fine and can continue with the feature tutorial.
i will repeat later the first step and see what goes wrong with it (eclipse 
luna + java 7+ geotools 11.2)
Thanks

 I have not had any trouble on this one, did you set up via eclipse or via 
download? What version of geotools are you using etc...
The module we are looking for is gt-epsh-hsql which uses the hsql database to 
"unpack" a copy of the EPSG database into a tmp directory.

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize
