Question: I am converting an existing POJO to be an JAXB compliant. Everything works fine except for one of the getter method of the pojo where I need an additional logic specific to rendering XML. However, this getter is already called somewhere within the application and I cannot modify this method's behavior.
How do I normally deal with such method name collisions? Is there a way I create a separate method just for JAXB purpose adn mark the currentmethod as XMlTransient?

Thanks
