I would do it like this:
Have a class something like:
public class Message {
private MyEvent myEvent;
//getters and seters for myEvent
}
Then, define a jibx binding like:
<mapping
class="xxx.MyEvent"
abstract="true" />
<mapping name="message">
<structure field="myEvent" type="xxx.MyEvent" />
</mapping>
<mapping name="createMyEvent"
class="xxx.CreateMyEvent"
extends="xxx.MyEvent">
<structure map-as="xxx.MyEvent" />
<!-- other fields -->
</mapping>
<mapping name="deleteMyEvent"
class="xxx.DeleteMyEvent"
extends="xxx.MyEvent">
<structure map-as="xxx.MyEvent" />
<!-- other fields -->
</mapping>
By having the above, depending on whether the message contains create or
delete event elements, the correct object will be populated in to the
field 'myEvent' in the Message object.

Hi All,
I am sure this problem has come up before, but I
can't find any examples or any help.
I have an interface:
public interface MyEvent
{
public void process () throws Exception ;
}
with several implementations in the form of:
public class CreateMyEvent implements MyEvent
{
public void process () throws Exception
{
// do something
}
}
public class DeleteMyEvent implements MyEvent
{
public void process () throws Exception
{
// do something
}
}
I am placing them in a JMS queue and would like them to be
remapped back to objects when they come out, so that I can
do something like:
while (mess = read from queue)
{
mess.process();
}
I have created a mapping binding for each MyEvent implementation
but have found that I can only use one de-serialiser at the
other end.
Please can someone help me with what the "right" way of achieving this
is.
Regards,
David
