Hi,
It seems to me that you have to go one level deep. See whether there
is a getAddress method in the Address class.
XMLBeans generates a lot of classes and things are a bit confusing
specially when types and elements have similar names. AFAIK XMLBeans
generates a class per type and element. So there would be a class
generated for the address type and also for the address element. My
guess is you have to check the address type object instead of the
address element object.

Thanks Ajith. Could you be more specific on how to figure out the right type
of the instance? Here is the code snippet and the output on the service
side.
The getAddressArray indeed returns Address[] which is good. But the
instanceof always returns Address even for USAddress instance. The
interesting thing is the toString output of the addr variable. It includes
the correct xsi-type for each instance. So how can I do the correct
instanceof to figure the right type to cast in this case?
Thanks,
-Bo
----Code snippet----
public void
updateAddresses(samples.quickstart.service.xmlbeans.xsd.UpdateAddressesDocument
param3)
{
//Todo fill this with the necessary business logic
String symbol = param3.getUpdateAddresses().getSymbol();
System.err.println(getCurrentTime()+"- Update Symbol:" + symbol);
Address[] addrs = param3.getUpdateAddresses ().getAddressesArray();
for (int i = 0; i < addrs.length; i++) {
Address addr = addrs[i];
if(addr instanceof USAddress) System.err.println("USAddress
instance");
if(addr instanceof Address) System.err.println("Address
instance");
System.err.println(addr.getClass().getName()+":"+addr);
}
...}
----Output from the code ----
