I developed simple REST API - https://github.com/pavelpetrcz/MandaysFigu - and my problem is that at localhost WildFly 16 server is app working properly. But I get error 404 at Tomcat 8.5.
This is my console when I ran app at Tomcat at localhost:

My colleague helped me and explained me that I have to add to my POM file dependency at some implementation for JAX RS which was initially missing. So I added:
<dependency>
<groupId>org.glassfish.jersey.bundles</groupId>
<artifactId>jaxrs-ri</artifactId>
<version>2.29</version>
<scope>provided</scope>
</dependency>
Afterwards it still works at WildFly but does not work at Tomcat. I think I should maybe add some other implementation of other JEE standards.
I expect, that I can run my app at Tomcat 8.5 as well as at WildFly and could publish that app at Heroku.
Could anybody help me to figure out what I should do next?
Tomcat is java web server (Servlet/JSP container). Is not a JEE server with all the complete functionalities like WildFly, WAS Liberty, Glassfish,...
The dependency org.glassfish.jersey.bundles:jaxrs-ri is marked as provided. This means that maven asumes that the dependency is already in your runtime environment and is not added to the package. This is true in WildFly that contains JAX-RS implementation but Tomcat misses it and is required to be added as a dependency, removing the scope provided uses the default scope and is added to the package, but this could make conflicts with the WildFly implementation (check it).
Other option is add the dependency in Tomcat as server library in the endorsed libraries to stay available on any time.
