deserialization error: no deserializer is registered

 Hello All,
I am getting the following error :
deserialization error: no deserializer is registered for (null, 
{http://com.test/types/HelloWebservice}HelloBean 
<http://com.test/types/HelloWebservice%7DHelloBean>)

at DIIHelloTest.main(Unknown Source)

In the above example, the webservice is returning a vector of HelloBean 
objects (with HelloBean being a regular Java Bean and implements 
serializable).
I am encountering this problem when I use DII to invoke the service. It 
works fine if I were to use stubs directly.
Thanks
