Hi, I had a case that resembles this one and I found a workaround without using a custom marshaller/unmarshaller. My case had some 'lucky' conditions but maybe they will also apply to you.
I created an abstract mapping which reads the 'type' tag value into a field. The extending mappings are as usual and matched this same xml structure. (This means that only the first type of concrete class will ever get created but it will hold its correct type String in the 'type' field.). In the class containing these polymorphic objects (hopefully you have one since this is the trick here) I created a post-set method. This method iterates over the polymorphic objects, checks their 'type' string field and creates a different Instance according to that type (if it differs from instanceof what I expect). Perhaps I didn't explain this too well, but I hope you get the general idea.

The only way I can suggest to handle that is by using a custom marshaller/unmarshaller for this structure. It'd need to parse past the <object> start tag and get the <type> element contents in order to know what type of object to create for the value. You can find out the basics of custom marshaller/unmarshallers at http://jibx.sourceforge.net/tutorial/binding-custom.html#marunmar - Dennis Dennis M.
