      I'm building a custom Wildfly 34.0.0.Final using Galleon 6.0.4.Final for use in a container image. I'm using the mvc-krazo layer which provides support for Jakarta MVC at preview level.

      I wanted to build an application using Apache Velocity and Jakarta MVC. Apache Velocity is not supported by Eclipse Krazo out-of-the-box. Therefore I needed to add a dependency for the custom engine: org.eclipse.krazo.ext:krazo-velocity:3.0.0.

      The GUI is contained in a WAR which is contained within an EAR. When I deploy the EAR and access http://localhost:8080/jakarta-mvc-custom-viewengine-not-found/ui/gui/ , I expect to receive the HTML page rendered by Jakarta MVC. However, I receive status code 500. The wildfly log contains the message RESTEASY002010: Failed to execute: jakarta.ws.rs.ServerErrorException: Unable to find suitable view engine for 'test.vm'.

      When I deploy the GUI WAR by itself, the view engine is correctly found and used, i.e. accessing http://localhost:8080/jakarta-mvc-custom-viewengine-not-found-ui-1.0.0-SNAPSHOT/gui/ , returns the expected document.
