Hello, I've been trying for days to run a Jax-RS application in the following environment : - Tomcat 10.0.16 - Windows 11 - Eclipse 2021-12 and I finally found something weird.
I tried with two different implementations (RESTeasy and Jersey) and I get the same behavior each time : - when my implementation of jakarta.ws.rs.core.Application (say MyApp) is inside war classes (WEB-INF/classes), my application isn't loaded. - when my implementation of jakarta.ws.rs.core.Application (MyApp) is inside a dependency (WEB-INF/lib), my application is properly loaded. I used debug with RESTeasy and Jersey implementation : each time, their implementation of jakarta.servlet.ServletContainerInitializer (respectively org.jboss.resteasy.plugins.servlet.ResteasyServletInitializer and org.glassfish.jersey.servlet.init.JerseyServletContainerInitializer) received MyApp in the 'classes' set of 'onStartup' method only when MyApp is bundled into a dependency. So far, the problem seems to relate to the jakarta.servlet.ServletContainerInitializer implementation. It is a change since servlet 3.0 spec. Is it intended by servlet 5.0 spec or is it a bug in Tomcat 10.0.16 implementation ?
