I'm trying to deploy a web application on Glassfish, and it's failing with the error "One or more web fragments define the same Servlet in a conflicting way, and the Servlet is not defined in web.xml", which is strange, given that the application deploys perfectly on Tomcat.
That's the message that appears in the log

I have looked at the log from top to bottom, and there's no indication on what is causing the conflict.
Is there any way of finding out what exactly is causing the alleged conflict?
