I'm trying to containerize a couple of applications using a Tomcat Docker container, but for some reason Tomcat isn't able to start one of the applications.

It's supposed to deploy and run two different WARs, a dashboard app and a service app which powers the dashboard. Other developers and I have both applications working in our local environments with Netbeans as well as on a Tomcat instance on a server. After building and running the container I'm able to get to the Tomcat default page and I'm able to access the service app, however the dashboard app doesn't start. The DOCKERFILE is very simple it's basically just:

FROM tomcat:8.0-jre8



COPY ./*.war /usr/local/tomcat/webapps/

COPY tomcat-users.xml /usr/local/tomcat/conf/

EXPOSE 8080

After running "docker run" for the first time the catalina log gives the message:

org.apache.catalina.core.StandardContext.startInternal One or more Filters failed to start. Full details will be found in the appropriate container log file

The localhost log file where it seems to put the details has the following message:

When I go to the Tomcat Web Application Manager page it recognizes the dashboard application, however when I try to start it using the provided start button it gives the same message in the catalina log and a bit of a different localhost log message as follows:

The kicker is that I know that it was working several months ago when I set this project aside. I don't remember a problem like this when I first set it up and after coming back to this project I haven't changed anything so I'm not sure what could be going wrong.

I've also tried putting the two apps in different containers (which is probably the architecture I should strive for anyways), and the results are the same.
