Java EE (Java Enterprise Edition) General Discussion

When I built my Java application that uses JAXB in it, javax.xml.bind.JAXBException: "com.xxx.model.configuration" doesnt contain ObjectFactory.class or jaxb.index occurs.
The source code runs well in eclipse or netbeans, but when I build a setup file by using BuildDesk, this exception occurs. I am using the following source code to generate the JAXBContext:
Line: -----
@SuppressWarnings("unchecked")
public static <T> T unmarshal(String packageInfo, InputStream is) {
try {
JAXBContext jc = JAXBContext.newInstance(packageInfo);
Unmarshaller unmarshaller = jc.createUnmarshaller();

JAXBElement<T> je = (JAXBElement<T>) unmarshaller.unmarshal(is);
return je.getValue();
} catch (JAXBException e) {
e.printStackTrace();
}
return null;
}
Line: -----
Exceptions are as follows:
