JAXB marshalling error..

Question

Hi, below codes is working properly with normal java app. ( public static void main(String[] args) { ... } )
try {
    FileOutputStream fout = new FileOutputStream(new File("C:/workspace/mysearch/data/", name));
    JAXBContext ctx = JAXBContext.newInstance(Project.class);
    Marshaller marshaller = ctx.createMarshaller();
    marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
    marshaller.marshal(project, fout);
} catch (JAXBException ex) {
      ErrorManager.getDefault().notify(ex);
} catch (Exception ex) {
      ErrorManager.getDefault().notify(ex);
}but, it is not working with the Netbeans WizardAction's performAction() method. below is error messages.

Heya,
I have no supportting evidence for this, but I'd assume if you annotate the property in the way shown in your example, the framework would then try to generate the appropriate getter() method to be used when marshalling the data. I'd guess you could annotate the property with the @XmlTransient annotation and use the default getter() method and avoid this error, no ?
Good luck,
