Hallo,

ich habe eine @post methode für einen Restful geschrieben, der einen per xml übermitteleten String in ein Objekt umwandeln soll. Hierzu verwende ich den Unmarshaller und bekomme den folgenden Fehler nicht behoben:

Der XML String sieht wie folgt aus:
XML: 
<dEmails>
<dEmail>
<email_text>test 1</email_text>
<email_type>Studiengangsinformation</email_type>
<toRecipients>andy@web.de</toRecipients>
<ccRecipients>andy@web.de</ccRecipients>
<bccRecipients>andy@web.de</bccRecipients>
<headline>test 1</headline>
<selfCopy>true</selfCopy>
<creator>Andy</creator>
<creation_date>null</creation_date>
</dEmail>
</dEmails>

die @POST Methode sieht wie folgt aus:
Java: 
 @POST
    @Path( "create/email" )
    @Consumes(MediaType.APPLICATION_XML)
    @Produces( MediaType.APPLICATION_XML )
    public DEmail createEmail(String xml)
    {
        System.out.println("XML: " + xml);
        
        JAXBContext jaxbContext = null;
        DEmail email = null;
        
        try
        {

            jaxbContext = JAXBContext.newInstance(DEmail.class);
            Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
            email = (DEmail) unmarshaller.unmarshal(new StringReader(xml));

        }
        catch ( JAXBException e )
        {
            e.printStackTrace();
            SC.say( String.valueOf( e ));
        }
        return email;
    }

Meine Entety Klasse so:

Ok habe die Lösung gefunden. Ich musste nur das <DEmails> weglassen, weil ich damit auf eine Liste verweise, in wirklichkeit mich aber nur auf ein Objekt beziehe Wenn ich den String wie folgt anpasse funktioniert es:

XML: 
<?xml version="1.0" encoding="UTF-8"?>
<dEmail>
<email_text>test 1</email_text>
<email_type>Studiengangsinformation</email_type>
<toRecipients>andy@web.de</toRecipients>
<ccRecipients>andy@web.de</ccRecipients>
<bccRecipients>andy@web.de</bccRecipients>
<headline>test 1</headline>
<selfCopy>true</selfCopy>
<creator>Andy</creator>
<creation_date>null</creation_date>
</dEmail>
