> If you let axis convert POJOs to a webservice which contain HashSet objects you will run into the problem that you get the HashSet as a list via SOAP but you are not able to sent this list back. You will face an "argument type mismatch" error.
> This happens because inside the source code there is a check if the class of the property is a subclass or implementor of Collection which is the case for HashSet. But if this check is true, an ArrayList is build up every time, but ArrayList is not the only class which implements Collection, so this will lead to errors for each class implementing the Collection interface beside the ArrayList class.
