Subject Re: Tomcat 8.5.13 - random issue with HTTPS (blank page) - working good with HTTP
Date Wed, 06 Mar 2019 12:43:35 GMT
Check your log4j configuration .. make sure it's got a console
appender configured (based on the log file names, it would seem like a
console logger will be required).  If you can, try to post up your
log4j configuration .. there will be key classes for logging within
tomcat that must be enabled.
