QUESTION
I am not sure what is missing from this jar file but when I try to run the jar from the command line, it cannot load the main entry point:
This is the directory that contains the classes and the resources for my application.
ANSWER
Answered 2020-Sep-05 at 06:03I discovered something interesting in respect to the HelloWorld.java that I mentioned in my last comment. I abandoned using the "jar cvfe" and instead created a file name mymanifest.txt and placed the name of the class with the main entry as "Main-Class: org.me.HelloWorld" followed by two blank lines (per specification). I packaged the jar using the "jar cvmf" instead of "jar cvfe" and it WORKED FINE. I then applied the same method to my application jar creation, and now I am getting a Linkage Error instead of ClassNotFoundException. Perhaps, it has something to do with the JavaFX library that I have to investigate deeper. In summary, I suspect that the "jar cvfe" switch might not be working as described in the Java tutorial. I have had found errors in the tutorial in the past and this MIGHT be another one.
Anyway, thank you all for your comments.

QUESTION
I can't manage to get a simple REST service working. As far as I can tell by the numerous examples I've read, I only need to return a POJO while having the jackson dependencies fulfilled in order to get a json response in the client.
I'm using IntelliJ Idea (EE) as my IDE and tomcat7 as the web server. Tomcat logs register the deployment and the facets configuration within the IDE is identical to other non-rest working examples I've done. Tomcat access log gives me this error when calling the /index mapping from my browser:
127.0.0.1 - - [21/Mar/2017:13:10:45 +0100] "GET /index HTTP/1.1" 404 949
This is the code of the REST controller (it's logged as an error so I don't miss it):
...ANSWER
Answered 2017-Mar-21 at 14:20You have an annotation on controller class level and method level, so your url must be /index/index
