Answer 1

You can implement your own Appender and copy all logs on it using the normal config:

log4j.rootLogger=WARN, file, other

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=${catalina.home}/logs/log.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ISO8601} %p %t %c - %m%n

log4j.appender.other=class.path.of.your.Appender
