I respond to myself and others who may come across in the future :)
By using the following JAXB customization, you can get past the data types
issue (and also the problem with JAXB generating List types for 'unbounded' xml
elements - which seem to be a problem with Axis2 since it looks for setter
methods while deserializing)

Subject: Issue with BeanUtil.deserialize()
Hello,
BeanUtil.deserialize() throws a java.lang.InstantiationException when trying to
deserialize an xml fragment. The java classes were generated using wsdl2java
and jaxbri binding. One of the xml elements is 'notificationInterval' with data
type 'xs:duration' which gets mapped to javax.xml.datatype.Duration by JAXB.
When an xml fragment containing this type is being unmarshalled, BeanUtil fails
because it is trying to instantiate an abstract class (since Duration is
abstract).
Is there a way to get past this problem?
Attached are the generated classes and the xml fragment.
Thanks,
Murali
Note: I was able to get past a similar problem with XMLGregorianCalendar by
using jaxb customization (to create java.util.Calendar)
