I followed the steps for WAR deployment to a Tomcat server. I have Tomcat 9 installed and running, and the 2 WARs are in the webapps directory. When trying to load the app, I just get a blank screen with “Unexpected error - please contact system administrator” and a Retry button.
Looking into the app.log reveals the following chain of errors:
