https://www.tutorialspoint.com/restful/restful_first_application.htm

when i added project to tomcat 8.5 in eclipse and trying to start tomcat i am getting below error

Server Tomcat v8.5 Server at localhost failed to start.
are these below 3 same jar or different jars?

\jaxrs-ri-2.17\jaxrs-ri\api
\jaxrs-ri-2.17\jaxrs-ri\ext
\jaxrs-ri-2.17\jaxrs-ri\lib
jaxrs-ri seems jar right which has api and ext and lib within that?
