Unable to launch WSO2EI with log4j slf4j appender Kafka

问题

I've updated my WSO2 EI from 6.2.0 to 6.3.0 and now i can't launch my WSO2 with a log4j appender for Kafka.

Before, i've put this in my log4j.properties

log4j.rootLogger=ERROR, CARBON_CONSOLE, CARBON_LOGFILE, CARBON_MEMORY,CARBON_SYS_LOG, ERROR_LOGFILE, KAFKA
log4j.logger.AUDIT_LOG=INFO, AUDIT_LOGFILE


log4j.logger.KAFKA=INFO
log4j.logger.org.apache.KAFKA=INFO
log4j.logger.KAFKA=DEBUG
log4j.logger.org.apache.KAFKA=DEBUG
log4j.logger.KAFKA=FATAL
log4j.logger.org.apache.KAFKA=FATAL
log4j.logger.KAFKA=WARN
log4j.logger.org.apache.KAFKA=WARN
log4j.logger.KAFKA=ERROR
log4j.logger.org.apache.KAFKA=ERROR

# Appender config to send KAFKA
log4j.appender.KAFKA=org.apache.kafka.log4jappender.KafkaLog4jAppender
log4j.appender.KAFKA.brokerList=myKafkaQueue:9092
log4j.appender.KAFKA.topic=log_raw
log4j.appender.KAFKA.layout=org.apache.log4j.PatternLayout
log4j.appender.KAFKA.layout.ConversionPattern=DATE:%d{yyyy-MM-dd HH:mm:ss.SSS};; HOST:HOSTNAME;; SEVERITY:%p;; MSG:%c{1}:%L - %m;;

and then i've got this error when i launch ./integrator.sh

No org.slf4j.impl.StaticLoggerBinder found in ClassPath, trying with log4j...

For Kafka, i'm using this 3 libraries inside my "lib" folder : - kafka-clients-1.1.0.jar - kafka-clients-1.1.1.jar - kafka-log4j-appender-1.1.1.jar

This is what i already did : - I updated my kafka-clients and kafka-log4j-appender - I've tried with WSO2 6.5.0 and 6.6.0 but it didn't works - I've tried to recompile WSO2 EI 6.3 - 6.6 with the older version of log4j and slf4j (i changed version inside pom.xml)

I've compared 6.2.0 with newer version and i found that WSO2 doesn't not use slf4j but slf4j.wso2 since 6.3.0.

Do you have any idea ? Thank you.
