Hi,
Following is my deployment env:
tomcat7
|- lib/sharedLib12.jar // shared lib used by webapp1 and webapp2
|- lib/slf4j-api-1.7.7.jar, log4j-api-2.3.jar, log4j-core-2.3.jar,
log4j-slf4j-impl-2.3.jar
|
|- webapps
|-webapp1/WEB-INF/classes/log4j2.xml
| lib/log4j-web-2.3.jar
|-webapp2/WEB-INF/classes/log4j2.xml
| lib/log4j-web-2.3.jar
With servlet 3.0+ and default ClassLoaderContextSelector, it was
quite simple (awesome!) to config so that log output from each webapp
will be sent to it's own log file (webapp1.log, webapp2.log)
But the problem is that log output from the sharedLib jar will always
goto to the first loaded webapp, because:
----------> Parent Classloader:
org.apache.catalina.loader.StandardClassLoader@59717824
the parent classloader (the one sharedLib is loaded) will be assigned
to the loggerContext of the first loaded webapp (which kinda makes
sense).
Question:
is there a way to config so that jars inside the tomcat/lib can be
logged to a common/separate logger context (or log file) that is
independent of the loaded webapp? (without configure tomcat to use
log4j2 as internal logger?)
Thanks!
Bill
