Making classes serializable

Making schema-derived classes serializable

According to the Java Persistence API specification, section 2.1, entities must implement the serializable interface:

If an entity instance is to be passed by value as a detached object (e.g., through a remote interface), the entity class must implement the Serializable interface.

Hyperjaxb2 itself does not enforce serializable classes generation, you should use the jaxb:serializable global bindings customization element to make your model serializable:

bindings.xjb

<jaxb:bindings version="1.0"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    
    <jaxb:bindings schemaLocation="schema.xsd" node="/xsd:schema">
        <jaxb:globalBindings localScoping="toplevel">
            <jaxb:serializable/>
        </jaxb:globalBindings>
    </jaxb:bindings>
</jaxb:bindings>
