The ALE middleware doesn't seem to pick the InputGenerators.properties  file. I've tried messing around with it, but I'm not very experienced with Java.
I followed the documentation and placed both files in the designated directory (/usr/local/tomcat/webapps/fc-server-1.2.0/WEB-INF/classes).
I'm doing my master thesis and the objective right now was to get the EPCIS server & repository, middleware and capture application working, publishing EPCIS events of a physical Impinj Speedway reader.
I'm orchestrating everything with docker, using tomcat 7 (above versions generate errors, didn't look deep in to that) and openjdk version "1.8.0_252" .

I've put the log level to ERROR and this is what I get:

Missed some lines in the log:
