OK Rainer i moved log4j-core-2.6.2.jar, log4j-api-2.6.2.jar,
log4j-jul-2.6.2.jar and log4j2.xml to $CATALINA_HOME/bin
Then changed
set
JAVA_OPTS=-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
set LOGGING_CONFIG=-DnoOpp
set
LOGGING_MANAGER=-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
set
"CLASSPATH=.;%CATALINA_BASE%\bin;%CATALINA_BASE%\bin\log4j-core-2.6.2.jar;%CATALINA_BASE%\bin\log4j-api-2.6.2.jar;%CATALINA_BASE%\bin\log4j-jul-2.6.2.jar"
then all woked fine THX frank

Currently you need to put three log4j2 jar files into the CLASSPATH (not the
lib directory):
- core
- api
- jul bridge
Next put your log4j2.xml in some special directory and add that directory to
the CLASSPATH as well.
Since in 8.5 Log4J integration is via its jul bridge it must be loadable by
jul, that's why CLASSPATH and not just the lib directory.
Finally add the following system property to inform jul that it should log via
log4j2:
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
for instance by setting LOGGING_MANAGER to that value. To reduce confusion I
suggest to also set LOGGING_CONFIG to some dummy value, e.g.
-Dnop.
See:
http://logging.apache.org/log4j/2.x/log4j-jul/index.html
There is a (minor) flaw currently in this integration: the location info (class
name, method name, line number) will be wrong and always point to a fixed
position in Tomcat Juli instead of the "real" class calling the log method.
