How to redirect tomcat logs TO console?
There is Tomcat configuration file for the logging: TOMCAT_HOME/conf/logging.properties.
Edit the file and remove all the handlers except the console handler:

.handlers = java.util.logging.ConsoleHandler


This will direct all logging to the console, except for access logs (localhost_access_log.XXXX.txt). It is always written to file by the AccessLogValve, configured in 'server.xml'. To redirect that one you need to configure own implementation of the AbstractAccessLogValve... which requires coding.
