XML databinding in Java using Castor

Often in my applications, I needed to persist some Java data objects as XML. For this I used to use JDOM which was quite cool to use bcoz of its Java-like API.
But there is one more XML data binding framework known as "Castor" which can handle all the marshalling and unmarshalling of object to XML for you automatically or with the help of a mapping file. Castor is indeed a cool XML data binding framework.
