Hi
My server application which receives XML-Messages must treat 2 different
specification versions of the XML-File. Most of the types, attributes and
elements stay the same between the versions (98%) but some are different
(mandatory/optional, existing/not existing, renamed elements).
I thought of resolving this problem like this:
- having 2 different schemas which include a third schema where the
unchanged items are declared
- let castor build the classes in two different subpackages
- creating wrapper classes for each castor generated class which implements
an interface
- working only with the interface
The problem is now, that there are really a lot of elements and types. I
have to create for each castor generated class one interface and two
wrappers (one for each version. Maybe I must support three or even more
versions in future) -> much boring error-prone work.
Is there annother way of addressing such an issue? I particular the common
unchanged types and elements should be wrapped into the same class (not
different classes with the same name in different sub packages).
Heri
BTW: Castor 9.5.2, java 1.4.2
