java xml jaxb Java

I'm having trouble with I've been researching this but I'm attempting to set up I'm trying to configure I've searched everywhere and can't find a clear answer. After trying multiple solutions online, I still can't figure this out. I'm currently working on a Java application that uses JAXB to parse XML files into Java objects. However, I'm working with an scenario where the XML elements aren't being mapped correctly to the object fields. The XML looks like this: ```xml <person> <name>John Doe</name> <age>30</age> <email>john.doe@example.com</email> </person> ``` And my corresponding Java class is: ```java import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement(name = "person") public class Person { private String name; private int age; private String email; @XmlElement(name = "name") public String getName() { return name; } public void setName(String name) { this.name = name; } @XmlElement(name = "age") public int getAge() { return age; } public void setAge(int age) { this.age = age; } @XmlElement(name = "email") public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } } ``` When I run the code to unmarshal the XML like this: ```java import javax.xml.bind.JAXBContext; import javax.xml.bind.JAXBException; import javax.xml.bind.Unmarshaller; import java.io.StringReader; public class Main { public static void main(String[] args) { String xml = "<person><name>John Doe</name><age>30</age><email>john.doe@example.com</email></person>"; try { JAXBContext context = JAXBContext.newInstance(Person.class); Unmarshaller unmarshaller = context.createUnmarshaller(); Person person = (Person) unmarshaller.unmarshal(new StringReader(xml)); System.out.println(person.getName() + " - " + person.getAge() + " - " + person.getEmail()); } catch (JAXBException e) { e.printStackTrace(); } } } ``` I receive a `javax.xml.bind.UnmarshalException` with the message: "unexpected element (uri: , local: person)". I've double-checked the XML structure and the annotations in the Java class, but I need to seem to figure out why it's not mapping correctly. I've also tried switching the `@XmlElement` annotations to `@XmlAccessorType(XmlAccessType.FIELD)` to make the fields accessible directly, but that hasn't resolved the scenario either. Any insights or suggestions on what might be causing this question would be greatly appreciated! This is part of a larger web app I'm building. Is there a better approach? This is my first time working with Java 3.9. Any pointers in the right direction? I recently upgraded to Java stable. The stack includes Java and several other technologies. I'd love to hear your thoughts on this. This is my first time working with Java 3.11. Is there a simpler solution I'm overlooking? Any help would be greatly appreciated! For reference, this is a production desktop app.
