[FIXED] Tomcat cannot start after bad war file

Issue

I deployed a war file to my Apache Tomcat 9 server using the tomcat web manager, the application was having issues so I restarted the server. I noticed that the server does not boot due to some errors for the war file.

I deleted the project folder and the war file under /var/lib/tomcat9/webapps

But when I try to start Tomcat, it still tries to find the project I have deleted.

What can I do to fully get rid of the project in Tomcat so I can make it boot up again?

Solution

The issue was that I had a virtual host pointing to the application. I commented it and tomcat booted up
