Por que meu log4j.properties não filtra as mensagens do JSF?

Assuntos Gerais
#1

Olá, estou tentando usar o log4j para mostrar apenas mensagens do nível de Warning pra cima, mas não consigo filtrar as mensagens que vêm do JSF, como a abaixo: INFO: Initializing Sun’s JavaServer Faces implementation (1.2_05-b06-FCS) for context ‘/…-…’. Eu percebi que quando removo o log4j.properties as mensagens continuam aparecendo (só muda que aparece a mensagem de erro por não encontrar o log4j.properties). Se eu remover algumas linhas de filtragem, nada muda. Não sei mais o que fazer.
Estou enviando abaixo como está meu configurador.

# ***** Set root logger level to WARN and its only appender to A.
log4j.rootLogger=WARN, A

# ***** A is set to be a ConsoleAppender.
log4j.appender.A=org.apache.log4j.ConsoleAppender
# ***** A uses PatternLayout.
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.logger.org.apache.catalina=WARN
log4j.logger.org.hibernate.cfg=WARN
log4j.logger.com.sun.faces=WARN
log4j.logger.com.sun.faces.config.ConfigureListener=WARN

O log segue abaixo:

Valeu…

Bom, depois de várias pesquisas, cheguei à solução. É preciso fazer alguns filtros no arquivo de logging também.
