Yeah that was the first thing I tried but I keep getting ClassCastException
whenever I try to downcast an object from the list to either ObjectOne or
ObjectTwo.
I now also tried to use @XmlSeeAlso - had to put it in the service interface
so they would appear in my wsdl but it makes no difference
(@XmlSeeAlso(value = { ObjectOne.class, ObjectTwo.class })); still a
ClassCastException.
If I use List I also get an exception: java.lang.ClassCastException:
org.apache.xerces.dom.ElementNSImpl
Am I doing something wrong here?
