Hello there, I've realized that if I make a typo in my <filter-class> declaration I get something in the catalina.out like:
Apr 03, 2018 2:27:01 PM org.apache.catalina.core.StandardContext startInternal SEVERE: One or more Filters failed to start. Full details will be found in the appropriate container log file Apr 03, 2018 2:27:01 PM org.apache.catalina.core.StandardContext startInternal SEVERE: Context [/examples] startup failed due to previous errors The catalina.log gives me the same information :( I have also tried increasing the logging level of org.apache.catalina.core adding org.apache.catalina.core.level = ALL org.apache.catalina.startup.level = ALL into my ${CATALINA_HOME}/conf/logging.properties I did not get any useful information neither. Is there a way of debugging these kind of issues? Thanks in advance, Luis Server version: Apache Tomcat/9.0.5 Server built: Feb 6 2018 21:42:23 UTC Server number: 9.0.5.0 OS Name: Linux OS Version: 4.4.0-116-generic Architecture: amd64 JVM Version: 1.8.0_151-b12 JVM Vendor: Oracle Corporation Tomcat running on docker FROM tomcat:9.0.5-jre8-alpine Alpine release 3.7.0 Linux d799b4063c4c 4.4.0-116-generic -- "Ever tried.
