Could it be my appender/logger configuration then? The situation is, under normal configuration [tomcat's juli logging], my my webapps writes separately to catalina.log and localhost.log. But when I configure logback, the catalina.log only has tomcat logging and all my webapps loggings ends up in localhost.log. Below is my logback.xml:
<?xml version="1.0" encoding="UTF-8"?>
