Does anyone know if it is possible to set a default value for an element or attribute when we use Castor to marshal an object to XML? The objects that are marshalled to XMLs are fetched from a database. Some of the fields of these objects maybe NULL and hence their coresponding XML field/attribute is not printed in the XML. Is there a way to give a default value to such fields so that even if the database value is NULL it will display the default value in the XML (other than using a null check for all such fields in Java code)?
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
