Hi,
I already answer to similar question last week and I also updated the
provided org.ops4j.pax.logging.cfg file.
You are not so far but you have a mistake in your config.
Can you try the following:
log4j2.logger.myClass.name = com.myproject.mypackage
log4j2.logger.myClass.level = INFO
log4j2.logger.myClass.additivity = false
log4j2.logger.myClass.appenderRef.MyClassAppender.ref = MyClassAppender
log4j2.appender.MyClassAppender.type = RollingRandomAccessFile
log4j2.appender.MyClassAppender.name = MyClassAppender
log4j2.appender.MyClassAppender.fileName = ${karaf.log}/myclass.log
log4j2.appender.MyClassAppender.filePattern = ${karaf.log}/myclass-%i.log
log4j2.appender.MyClassAppender.append = true
log4j2.appender.MyClassAppender.layout.type = PatternLayout
log4j2.appender.MyClassAppender.layout.pattern = ${log4j2.pattern}
log4j2.appender.MyClassAppender.policies.type = Policies
log4j2.appender.MyClassAppender.policies.size.type =
SizeBasedTriggeringPolicy
log4j2.appender.MyClassAppender.policies.size.size = 8MB
Regards
