Thanks a lot Andrea, it works.
It took me one week ton figure out that the tomcat version shipped with fedora was not able to work with another java version 
I had to install tomcat version from apache website.
Thanks again.

Thanks Andrea for your answer,
Yes i have an ecore-2.2.2.jar in geoserver/web-inf/lib. No other ecore jar.
My jdk comes from sun. I have also tried with jre1.5.Question : could it be relative to the fact that i’m running my linux in
headless mode (with -Djava.awt.headless=true)?
Nope, look here:
I alse see an other error with demo data when deploying :
java.lang.UnsupportedOperationException: Cette transformation affine
n’est pas modifiable.

org.geotools.referencing.operation.transform.AffineTransform2D.checkPermission(AffineTransform2D.java:80)

org.geotools.referencing.operation.matrix.XAffineTransform.setTransform(XAffineTransform.java:167)
at java.awt.geom.AffineTransform.(libgcj.so.7rh)
Uagh, libgcj!!! GeoServer works only on fully compliant
java runtimes, gcj is still not up to snuff (and it would be very
very slow anyways).
I suggest you grab jdk 6 from Sun and retry, things should work
better 
Cheers
Andrea
