I'm trying to convert my xml file with java jabx , but in my case I don't get any error but it still returns null object, I use @XmlAccessorType(XmlAccessType.FIELD) , to get only the file I want.

ListMessageUser que = (ListMessageUser) jaxbUnmarshaller.unmarshal(file);
//[dateGen=null, listMessages=null]

exemple imput file XML

<?xml version="1.0" encoding="UTF-8"?>
<ListMessageUser xmlns="https://myapp.fr/schema">
    <DateGen>2022-06-17T11:01:43Z</DateGen>
    <ListMessages>
        <Message>
            <Name>test</Name>
            <Description>Message test</Description>
            <DateMAJ>2022-04-15T12:47:39Z</DateMAJ>
        </Message>
        ....
    </ListMessages>
<Signature xmlns="...">
    <SignedInfo></SignedInfo>
    <SignatureValue></SignatureValue>
    ...
</Signature>
</ListMessageUser>

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(namespace = "https://myapp.fr/schema", name = "ListMessageUser")
public class ListMessageUser {
    
    private String dateGen;

    @XmlElementWrapper(name="ListMessages")
    @XmlElement(name="Message")
    private List<MessageXml> listMessages;

    /// Constructor
    /// Getters and setters
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "Message")
public class MessageXml {
    
    private String name;
    private String description;
    private Date dateMAJ;
    
    /// Constructor
    /// Getters and setters
}

can someone tell me what is wrong with my code ?

or clue ?
