I have a Grails application that I would like to deploy to a tomcat instance. Relevant versions of the libraries used:
Grails Version: 3.2.0
Groovy Version: 2.4.7
JVM Version: 1.7.0_79
Tomcat Version: 7.0.39
I built the WAR file (using grails war), uploaded it to the server, placed it in the webapp directory and restarted tomcat. The WAR file was unpacked as usual, but when I try to access the webapp index page, it simply returns a 404 error. If I manually placed a file called "ndex.html" in the webapp directory, then this file will be serviced. Therefore, I came to the conclusion that tomcat did not run the application at all.
I tried to check the logs for errors, but catalina.out is almost empty. Redeploying my webapp gives the following log output:
