I deploy to Wildfly, deployment successful, hit the home page with 'localhost:8080/myapp' and I get Internal Server Error:
2016-03-11 01:48:58,844 ERROR [org.apache.velocity] (default task-11) ResourceManager : unable to find resource 'layout.vm' in any resource loader.
I see no mention of 'layout' anywhere in my project. Where is this coming from?
It is default behavior of VelocityLayoutViewResolver in your bean viewResolver to search for a template layout.vm.
layout.vm is expected to serve as a frame or wrapper around the views determined by your controller. That's very handy, because you don't need to bother about how a special view and your general HTML page are merged.
Please see this for example this tutorial (start at 'Creating templates') and this question for details.
