yes possible. see in console should automatically logged in catalina.out
file. file should located under : $catalina_home/logs/
. notice multiple files like: catalina.yyyy-mm-dd.log
. that's because tomcat uses apache commons logging dailyrollingfileappender.
from tomcat official website:
when running tomcat on unixes, console output redirected file named catalina.out. name configurable using environment variable. (see startup scripts). whatever written system.err/out caught file. may include: uncaught exceptions printed java.lang.threadgroup.uncaughtexception(..) thread dumps, if requested them via scheme signal
when running service on windows, console output caught , redirected, file names different.
