Tomcat: SEVERE: Error listenerStart

Bonjour à tous !
Voilà j'essaye en peu vainement d'installer Alembik sous Debian-Lenny-apache2-tomcat5.5...
Cela se présente en 2 webapps : Alembic-web qui démare bien et Alembik-tout-court qui elle, refuse de démarer.
( TOMCAT : FAIL - Application at context path /alembik could not be started )

j'ai ceci dans le catalina du jour :
