@XmlRootElement not working in jersey rest

Question

ERROR:

MessageBodyWriter not found for media type=application/xml, type=class com.example.DemoRest2.Employee, genericType=class com.example.DemoRest2.Employee.

I want to return the object of Employee.class in xml format but getting above error. I am using @XmlRootElement annotation. However, it works fine when I return it in string format.

EmployeeRsource.java

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

@Path("employee")
public class EmployeeResource {

@GET
@Produces(MediaType.APPLICATION_XML)
public Employee getEmp() {
    
    Employee e1 = new Employee();
    e1.setName("Tom");
    e1.setAge(25);
    System.out.println(e1);
    
    return e1;
}
}

Employee.java

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Employee {

private String name;
private int age;
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public int getAge() {
    return age;
}
public void setAge(int age) {
    this.age = age;
}
@Override
public String toString() {
    return "Employee [name=" + name + ", age=" + age + "]";
}   

}

Getting "INTERNAL SERVER ERROR 500" on user interface

The Jakarta EE Working Group has announced that javax is now officially and finally renamed as jakarta with the release of the Jakarta EE 9 Platform and Web Profile specifications and related TCKs.

To use that @XmlRootElement, import jakarta.xml.bind.annotation.XmlRootElement, after adding following,

<dependency>
        <groupId>jakarta.xml.bind</groupId>
        <artifactId>jakarta.xml.bind-api</artifactId>
        <version>3.0.1</version>
    </dependency>

    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-jaxb</artifactId>
        <version>2.33</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-osgi</artifactId>
        <version>3.0.2</version>
    </dependency>
