In Spring OXM (object XML mapping), when converting an object to XML file, it hits following error message :

Is castor data binding framework included in Spring oxm?

Solution

The castor is an optional dependency in spring-oxm.jar, to use castor to marshaller or unmarshaller XML in Spring OXM, add this castor dependency into your Maven pom.xml file.
