It seems i found the major problem of this weird behavior. I exposed my WebService through an interface annotated with @WebService, then my ServiceBean implemented this interface which not worked at all. Later on i tried to annotate my ServiceBean directly which seems to work fine... Is this a known issue or did i still miss something?
