Hello
Is there any way to bind two XML elements (Bbb and Ccc) to the same java
field...???
I'm trying to obtain a polymorphic data structure using castor XML
Mapping....
The example below fails, but illustrates what I'm attempting to do......
Any assistance or pointers greatly appreciated...
Cheers
Mark
