Dan Diephouse closed CXF-759.
-----------------------------

    Resolution: Cannot Reproduce

Chunking should be enabled by default, so I don't know why it would hang. If you send along a WSDL (in a new JIRA issue), we'll take a look though.

> I am currently in the process of selecting a mechanism for building a java client for a SOAP Web Services API developed in .NET.  This API is fairly simple, except for a point: some data structures returned are relatively complex and involve inheritance.
> In this case, these object structures don't seem to be correctly deserialized.
> A detailed description follows: if anyone could help me either
> - improving the deserialization process in Cxf, or
> - obtaining a way to access the raw XML data (or the corresponding parsed object structure) returned, so that the client application can complete the deserialization process itself in an "ad hoc" way,
> I would very much appreciate it.
> Here is a very simple example after reducing the problem to its simplest form.
> /**
>  * Web service code
>  * C#
>  */
> [WebMethod]
> [XmlInclude(typeof(Dog))]
> [SoapInclude(typeof(Dog))]
> public Animal getAnimal()
> {
>     return new Dog("brown");
> }
> public class Animal // ...
> public class Dog : Animal // ...
> Here is the XML contained in the response to the invocation of getAnimal(): the xsi:type="Dog" indicates that an instance of the daughter class is returned:
> <?xml version="1.0" encoding="utf-8"?>
> <Animal xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:type="Dog" xmlns="http://tempuri.org/">
>   <species>Dog</species>
>   <color>brown</color>
> </Animal>
> And here is the client code, added to the auto-generated file obtained from 'wsdl2java -client':
> /**
>  * Client code
>  * Java
>  */
> org.tempuri.Dog dog = null;
> System.out.println("Invoking getAnimal...");
> org.tempuri.Animal animal = port.getAnimal();
> try {
>     dog = (Dog)animal;
> }
> catch (java.lang.ClassCastException e1) {
>     e1.printStackTrace();
> }
> if (dog != null) {
>     System.out.println("Color of dog: " + dog.color);
> }
> The trouble is that the cast from Animal (parent class) to Dog (daughter class) fails: a ClassCastException is thrown.
> Many thanks for any help on this issue,
