The point is that I can have only objects namely order and customer. The
order object is being loaded through hibernate and the customer object is
being loaded through lazy loading while loading the order object. So I will
only have the order object with a reference to the customer object and this
is what I can pass to the marshaller.
Is there not any way to create the xml of the parent while creating the
child xml ? that will be the ideal solution to my case.
I want the xml equivalent of something like (other details not show in the
xml below) -
<orderTb>
<customer>
<order.getCustomer().getCustomerId()/>
<order.getCustomer().getCustomerName()/>
</customer>
</orderTb>
