There are may ways to do this but I drop the following into the 
solr.war/web-inf/classes/logging.properties files:

handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

############################################################
# Handler specific properties.
# Describes specific configuration info for Handlers.
############################################################

org.apache.juli.FileHandler.level = FINE
org.apache.juli.FileHandler.directory = ${catalina.base}/logs/solr
org.apache.juli.FileHandler.prefix = solr.

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

Thanks for those informations !
I'm using tomcat 6, does somebody has a snippet of conf file
to set up the log level for all org.apache.solr.* classes ?
