Raj Anand commented on CXF-4849:
--------------------------------
Sergey,
I tried this feature with CXF 2.7.4-SNAPSHOT version and got the following
exception when trying to fetch the payload(generic type) from the
response(which is a parameterized class , ServiceResponse<T>).
java.lang.ClassCastException:
com.sun.org.apache.xerces.internal.dom.ElementNSImpl cannot be cast to
examples.service.Book.
Here Book is the payload class(Generic Type).
Following is the snippet of the code I am using,
GenericType<ServiceResponse<Book>> genericResponseType = new
GenericType<ServiceResponse<Book>>() {};
ServiceResponse<Book> res = webclient.get(genericResponseType);
...
assertFalse(!res.getPayload()); //throws ClassCastException as, res.getPayload
is of type Book, but at runtime its replaced by ElementNSImpl
ServiceResponse is the parameterized class with Book as payload.
Let me know if something is missing or erroneous here.
