Java :: Flex - BlazeDS Not Handling Inner Class DTO?

I've noticed BlazeDS has certain things it does not support and it is often difficult to find this out. Ex: polymorphism is not.One must create methods with different names as methods with the same name with different parameters create a conflict.I'm trying to find out if BlazeDS does not support Java static and non-static inner classes.

public class UserDTO {
private String name;
private AddressDTO adddress;
private PhoneDTO phone;

[code]...

The example code above will compile and the getUser method will work. A call to the updateUser or updatePhone methods on the other hand results in a BlazeDS error. Is there a special way to use inner classes in Flex or are inner classes not supported?

Here is an example of the error messages produced:

[BlazeDS]Cannot create class of type 'com.test.dto.UserDTO.PhoneDTO'.
flex.messaging.MessageException: Cannot create class of type 'com.test.dto.UserDTO.PhoneDTO'. Type 'com.test.dto.UserDTO.PhoneDTO' not found.

Example Flex code:

var thisPhone:PhoneDTO = new PhoneDTO();
thisPhone.phoneNumber = "8885551212";
updateTagsResult.token = userService.updatePhone(thisPhone);
