Hi Bogdan, It's easy to filter a collection, though you need to write your own collection load/store methods to do it. Easiest is to define an Iterator for going through the items of the collection, returning only those which match your criteria. This means the hasNext() method of the Iterator has to check if the current match has been read yet (using next()), and if so check to see if there's another match in the collection. Then use the <collection> iter-method attribute in the binding to specify the method returning the Iterator, and an add-method for adding items to the collection (if you're unmarshalling as well as marshalling). So basically you're hiding the actual Collection object, and instead using the method pair for all access to the collection.
