Hi,

In one of the projects that I am working on, have been sending xml
messages back n forth btw the client(swing) and the corba server. The
serialized objects(in xml representation) are rich complex types (with
nested objects within).Currently am using a homegrown java xml
serialization mechanism which I plan to replace with a databinding
framework like JAXB.
The server typically deserializes this xml to a java object and
applies some basic business validation and performs CRUD operations
via DAO layer.

I am finding that there is significant amt of overhead in sending
these complete xmlized object for insert and every subsequent update.
Question is how would one end up sending just xml delta(only the data
that has changed) on UPDATEs, instead of sending the complete
serialized object(xml).

This question was asked way back in 2002, suggestions were made to use
xpath, but wanted to followup and get more pointers.

Please also take a look at the original thread:

Any inputs will be very helpful.

Thanks,
