Actually, I don't think XMLBeans classes work that well as value objects
(I assume that's what you mean by VO). I tried converting a web services
test program I'd written to Axis2 using XMLBeans classes for the data,
and was stunned to see the performance drop by a factor of up to 10
compared to other implementations. The reason turned out to be that
accessing data from XMLBeans generated classes is much slower than
accessing the data from ordinary classes. Once I replaced the XMLBeans
classes with ordinary Java classes for use by the program logic, and
only used the XMLBeans classes for reading and writing XML, the
performance increased dramatically. This was an unusual case, in that
the processing made a lot of accesses to the data values in the objects,
but does demonstrate a real issue.
