Unable to import javax.jws.webservice for @WebService annotation

I am working on Eclipse IDE and creating a web-service program. IDE gives an error while importing import javax.jws.WebService; import javax.jws.WebMethod; error shows the import javax.jws can not be resolved

import javax.jws.WebService;
import javax.jws.WebMethod;

@WebService
public class Hello {
    private final String message = "Hello, ";

    public Hello() {
    }

    @WebMethod
    public String sayHello(String name) {
        return message + name + ".";
    }
}
