Issue on running a JAVA 13 JAX-RS project in Tomcat 9

I'm working on this simple project and have this problem:

HTTP Status 404 – Not Found
Type Status Report

Message /RestTestThree/myService/Calculator/

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Apache Tomcat/9.0.30

I use this setting: JDK 13, Eclipse 2019-12, Tomcat 9.

I tried different URLs and I hope this one is the correct one: 

http://localhost:8080/RestTestThree/myService/Calculator/

I tried both model 3 and 4. Tried different dependencies and versions.

When trying to run this project, at some point the Tomcat even won't start, giving the error

Server Tomcat v9.0 Server at localhost failed to start.

My files are as follows.
