Log4j problems after replacing tomcat7 to tomcat8

[Hani Nabwani]

Tomcat version 8.0.28.
Os: linux.3.14.44-32.39.

I am running tomcat8, before that i ran tomcat7 with no problems.
After new tomcat8 release i uninstalled tomcat7 and installed tomcat8.
Then the log file of my app is never created, i tried to search (find
command) i get nothing, also i tried to find log4j.properties  file,
also i cant find it.
Where tomcat8 save the log file?
Where tomcat8 save the log4j.properties file.

My log4j. properties file is:
log4j.rootLogger=ERROR, CA, FA
log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.Target=System.out
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%d{-MM-dd HH:mm:ss}
%-5p %c:%L - %m%n
log4j.appender.FA=org.apache.log4j.RollingFileAppender
log4j.appender.FA.File=${catalina.base}/logs/D12.log
log4j.appender.FA.MaxFileSize=5MB
log4j.appender.FA.MaxBackupIndex=10
log4j.appender.FA.layout=org.apache.log4j.PatternLayout
log4j.appender.FA.layout.ConversionPattern=[%d{-MM-dd HH:mm:ss}]
[%-5p] [%c:%L]: %m%n
log4j.logger.com.datastax.driver.core=ERROR

There is no such file in default Tomcat configuration (as distributed
by tomcat.apache.org).

Tomcat by default uses java.util.logging.   It is possible to
reconfigure it to use Log4J 1.x  (and some 3-rd party distributions
provided such configuration), but that is not the default
configuration.
