Tomcat8 error

[Ramaiah, Vanna G.]

I am installing v2.4.4 in Ubuntu /tomcat8 in  a new server - trying to replicate the production. I completed my installation, made the apache webapps changes, changed login page and restarted tomcat8. It worked fine. I was able to get the version by running http://localhost:8080/shibboleth-idp/status.
And there is no error in catalina.out. Then I started moving the config file one by one and inbetween did tomcat8 restart. As soon as I moved the relying-party.xml, tomcat8 restart starting throwing error. I moved all the following files but tomcat8 is throwing error. What am I missing?
- All 7 files in conf directory one by one.
- Metadata file in metadata directory
- entire Credentials directory

SEVERE: One or more listeners failed to start. Full details will be found in the appropriate container log file
