Hi Govind,
Ah ok, I see the problem now...
If you're just trying to marshal, and not unmarshal, you can disable the
constructor check as such:
<class name="MasterData" verify-constructable="false">
I need to update the code to handle classes with factory methods.
Currently the only factory method supported is a String based factory
method for Type-safe enums such as:
public static Object getValue(String);
In any case, the above should work for you.
