Unable to understand JAXB Unmarshalling behaviour

Question

Reference to my previous post. I have following code which is reading XML from the file.

logger.log(Level.INFO, \"testSchemaChange\");
JAXBContext jaxbContext =          


        

Answer 1

The problem you are seeing is because the JAXBContext isn't aware of your ObjectFactory class that contains the @XmlElementDecl annotation for the book element.

When you create a JAXBContext on a package name, the it will automatically pull in the ObjectFactory class. If you create a JAXContext on classes you need to explicitly include the class with the @XmlRegistry annotation (ObjectFactory in this case).
