Trying to get xwiki up on an Amazon Linux 2 instance behind an AWS Application Load Balancer. I’m using the manual .WAR file deployment instructions.
I can access a healthcheck page I created in webapps as a sanity check, but trying to connect to the xwiki app fails with a NullPointerException.
Here’s the seemingly relevant section of /var/log/tomcat/localhost.2020-07-27.log
Configuration files attached.
hibernate.cfg.xml.txt (16.0 KB) xwiki.cfg.txt (25.5 KB) xwiki.properties.txt (51.1 KB)
