getObject() throws IOException
Hi,
I have a simple MDB that send ObjectMessage. In the object message
I have an instance of "Order", Order has a Address. And Address is an abstract
class with two concrete implementations, AddressInfo and Airport
When my client which instantiates Order and assign an instance of AddressInfo to
the Order instance and the create an object message via TopicSession and send it
to MDB running in JBoss 2.4.4 (over RH Linux 7.2), I got an
IOException with the following:

My question is, can object message contains object with abstract class field? If not, what is the alternative?
If so, please enlighten me where I did something wrong. Thanks in advance.
