You need to downgrade Jersey to version 2.x.

<jersey.version>2.31</jersey.version>

The tomcat 9 and older version does not support Jakarta EE for support Jakarta EE you must use tomcat 10 which is NOT supported in eclipse yet.

Once you have done the above change. You need to change the imports from jakarta to javax in MyResources.java. as shown below.

import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;

change to

import javax.ws.rs.GET; 
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

Hope it helps.
