Well, I've found out that JAXB is able to do it, anyway. The error message reminded me that in the past there had been problems with serialization of interfaces. So, in desperation, I changed the Map<,> to HashMap<,> and afterwards the error message changed to class java.util.ArrayList nor any of its super class is known to this context. So, I changed the List<> to ArrayList<> in the signature of the web service method and now the web service works again. Of course, this "solution" is extremely ugly, so if somebody has some suggestions on how to fix the problem without resorting to signatures with concrete classes, please share your insights. Thanks!
